JavaScript and TypeScript agencies in Poland, ranked for 2027

Best JavaScript, TypeScript, React and Node.js companies in Poland

Przemysław Zalewski·Data verified: ·33 min read

The signal here is what agencies pay for, not what they claim: a company qualifies when its open roles on JustJoin.it require TypeScript, JavaScript, React, Node.js or Next.js. That is the one stack I work in every day, so this list is also where I compare myself most directly. I checked 125 JavaScript and TypeScript companies in the National Court Register, their latest financial statements and the job boards. 67 meet the criteria, and the 10 highest scores are ranked below. The top 10 sit in Wrocław (6), Warsaw (2), Kraków (2). I sell the alternative: one senior engineer working with AI agents.

In short: The highest-scoring JavaScript and TypeScript companies in Poland for 2027 are Itransition (score 87), Zaven (score 87) and Intellias (score 85). The 0 to 100 score combines court register data, the latest financial statement, Clutch client reviews, GoWork employee reviews and open roles on the job boards. Paid Clutch positions do not count.

The ranking

The order below is the score from five axes: transparency, client reputation, stability, specialization and activity. For this list, specialization measures the fit to the topic. Weights and the full method are on the guide page.

Financial figures come from the latest filing of the Polish company. For subsidiaries of foreign groups they can be far from the size of the real business. Read the pros and cons, then open the sources under each entry.

Itransition

Large global IT services group with a Warsaw entity, working in ERP, CRM, Microsoft Dynamics, Salesforce and data.

Clutch: 4.9 (42 reviews)Rate: 25–49 USD/hMin. project: 25,000 USDPremier Verified

Best for: Mid-size and large companies rolling out Microsoft Dynamics, Salesforce or an ERP that want a global vendor with a Polish invoice.

Pros

  • The Polish company reported 83.4M PLN of revenue and a profit of 3.6M PLN in its 2025 filing.
  • Clutch shows 4.9 from 42 reviews and a Premier Verified badge.
  • Itransition has been a Microsoft partner since 2008. The site also lists Odoo Silver, Salesforce and AWS partnerships.
  • The job boards showed 27 open roles, 24 of them remote.

Cons

  • The Polish company belongs to Itransition Holdco Limited, and Clutch puts the group headquarters in Decatur, GA.
  • The declared rate of 25 to 49 USD is the offshore band, so ask where your team will sit.
  • GoWork shows few employee reviews, all negative (0 positive, 4 negative), and 2 of them mention layoffs.

From their website and Clutch profile

  • The homepage claims 3,000+ engineers, 800+ clients and over 25 years in business. The Polish company in KRS dates from 2017 (source).
  • The homepage names only two clients, and most case studies describe an unnamed retailer, pharma company or manufacturer (source).
  • Clutch lists 12 offices, with headquarters in Decatur, GA, and Warsaw among them. The site shows no office list we could open (source).
  • The site lists a Microsoft partnership since 2008, plus Odoo Silver, Salesforce and AWS partnerships (source).

Clients they name: The Economist, OPED Digital Health Solutions

ERP and Microsoft Dynamics 365CRM and SalesforceCustom software developmentData and BIAI and generative AIManaged IT servicesPythonJavaDockerJavaScript

Verdict. Pick Itransition for Dynamics, Salesforce or ERP rollouts at company scale. For a small custom product, the 25,000 USD minimum and the global delivery model are a poor fit.

Zaven

Process-driven software house building web and mobile apps for construction, real estate and utilities companies, mainly Nordic.

Clutch: 5.0 (15 reviews)Rate: 25–49 USD/hMin. project: 10,000 USD

Best for: A web or mobile product for a construction, real-estate or utilities company that wants a small, steady team in Wrocław and does not need a brand name.

Pros

  • Profitable every year in the filings we checked, with the latest statement showing a profit of 1.1M PLN on 12.7M PLN of revenue.
  • Employee reviews on GoWork are positive (6 positive, 1 negative), the rarest thing on this list.
  • Twenty named case studies, most of them Norwegian construction and marine clients, so you can check the work.
  • Publishes its own scale on the about page: roughly ten projects a year. Few agencies admit how small they are.
  • Still hiring on the job boards (2 open roles on October 27, 2026).

Cons

  • Since September 2026 fully owned by Multishoring Holdings, a Warsaw data and integration consultancy, so strategy is decided outside Wrocław.
  • Fifteen Clutch reviews only, and the declared rate band of 25 to 49 USD is the offshore band, which raises the question of who writes the code.
  • A team of 10 to 49 cannot staff several roles at once; expect a queue for bigger projects.
  • Founding year differs between the site, Clutch and the court register.

From their website and Clutch profile

  • The site publishes its scale, with roughly 10 projects per year and about EUR 3M turnover in 2025 (source).
  • The site lists twenty named case studies, most of them Norwegian construction and marine clients such as Fonn, Grasp and Safran (source).
  • Age claims do not line up. The site says 15 years in business, Clutch says founded 2011, and the KRS entry in our file dates from 2014 (source).
  • The site shows no certifications, awards or partner badges (source).

Clients they name: Volve, Fonn, Grasp, Safran, Dionach, Bonduelle

Custom softwareMobile appsGenerative AICustom MCP developmentProduct UX/UI designStaff augmentationReactVueAngular.NET

Verdict. The most transparent small software house in Wrocław. It is profitable, its own people rate it well, and it publishes its size. Hire it for one well-defined product, not for a platform that needs five roles.

Intellias

Ukrainian-founded product engineering company with a Kraków entity, working on mobility, navigation, fintech and retail platforms.

Clutch: 4.9 (30 reviews)Rate: 50–99 USD/hMin. project: 50,000 USD

Best for: Automotive, navigation and fintech companies that need a large engineering team with domain experience and a budget above 50,000 USD.

Pros

  • The Kraków company reported 152.3M PLN of revenue and a profit of 8.4M PLN in its 2025 filing.
  • The site names domain clients such as HERE, TomTom and HelloFresh.
  • Clutch shows 4.9 from 30 reviews, and Intellias has held ISO 27001 since 2017.
  • The job boards showed 13 open roles, all remote.

Cons

  • The Polish company belongs to Iteality Limited, and the group was founded in Ukraine in 2002.
  • Employee reviews are negative on balance (26 positive, 28 negative), with 4 mentions of layoffs.
  • Three of the four Polish offices are coworking spaces, and all 13 open roles are remote.

From their website and Clutch profile

  • Intellias was founded in 2002. The about page says its first office outside Ukraine opened in Zurich in 2010 and does not mention Poland (source).
  • The site lists four Polish offices in Kraków, Warsaw, Łódź and Wrocław, and the last three are in coworking spaces (source).
  • Named clients include HERE, TomTom, HelloFresh and Zooplus (source).
  • Horizon Capital invested in 2018 (source).

Clients they name: HERE, TomTom, HelloFresh, Zooplus, Syngenta, Omio

Product engineeringAI and generative AIData engineeringCloud and application modernizationQuality engineeringManaged supportPythonAIAWSAzure

Verdict. Pick Intellias for mobility and fintech engineering, where HERE and TomTom are checkable references. The Polish entity delivers for a foreign group, so agree in writing who leads your project.

Blurify

Wrocław software house building custom web and mobile apps on AWS for education, industry and, on its English site, iGaming.

Clutch: 5.0 (26 reviews)Rate: 50–99 USD/hMin. project: 25,000 USD

Best for: Polish education, industry and public-sector clients who want a 50+ team with a Wrocław office, and iGaming companies through its English brand.

Pros

  • A 5.0 rating on Clutch from 26 reviews with named Polish clients such as Fundacja Orange and WSiP.
  • Profitable in 2025 (309K PLN on 9.3M PLN of revenue), two private individuals as owners (KRS), hiring on the boards (3 open roles).
  • Publishes a three-month warranty on critical bugs after launch and offers a free estimate, which few agencies put in writing.

Cons

  • Two brands, one company: blurify.pl is a general software house, blurify.com sells casino and sportsbook products. Ask which team you get and whether the iGaming side matters to your compliance.
  • The legal entity is Studio Software Sp. z o.o., so search KRS by that name, not “Blurify”.
  • Thin margin: the 2025 profit is a few percent of revenue. Too few employee reviews on GoWork to read the mood.
  • The AWS claim is three individual certifications, not a partner tier.

From their website and Clutch profile

  • blurify.pl presents a general software house for Polish education and industry. blurify.com positions the company as an iGaming developer with casino and sportsbook products (source).
  • The site lists fifteen case studies, several with named Polish clients such as Fundacja Orange, WSiP and WAGO (source).
  • The legal entity is Studio Software Sp. z o.o., which matters when you check the KRS (source).
  • The AWS claim rests on three individual certifications rather than a partner tier (source).

Clients they name: Fundacja Orange (MegaMisja), WSiP, WKS Śląsk Wrocław, WAGO, Vemcon, LifeTraq

Custom softwareWeb appsMobile appsMVPAI solutionsAWS and cloudReactNext.jsNode.jsPostgreSQL

Verdict. Good client reviews and clear written terms, with one question to ask before signing: which of the two businesses would build your product.

iTeamly

Kraków engineering partner offering product delivery, team augmentation and technology consulting to international product companies.

Clutch: 5.0 (7 reviews)Rate: 50–99 USD/hMin. project: 50,000 USD

Best for: Product companies that want Java, React or .NET engineers to join their own team under their own lead.

Pros

  • iTeamly reported a profit of 337K PLN on 11.7M PLN of revenue in 2025.
  • JustJoin lists 8 open iTeamly offers for Java, React and .NET roles, 7 of them remote.
  • All seven Clutch reviews give the top score.
  • The homepage shows logos of international product companies such as Roche, Lokalise and FLYR.

Cons

  • Clutch puts IT staff augmentation at 40% of the work, so many engagements place people rather than deliver products.
  • The site shows no case studies, no team size and no named leaders, so the logos are hard to check.
  • The company in the registry dates from 2022.

From their website and Clutch profile

  • The site has no case studies. Its 'Trusted by' logo strip (Roche, Uber, Lokalise, FLYR) uses image files labeled as partners (source).
  • The about page names no founders, team size or founding year (source).
  • The contact page gives KRS 0000965872 and an office at Armii Krajowej 18 in Kraków (source).
  • Clutch lists 7 reviews and founding in 2021, and puts IT staff augmentation at 40% of the work (source).

Clients they name: Roche, Lokalise, WGSN, FLYR, ArisGlobal, Uber

Product deliveryIT team augmentationTechnology consultingAI/ML and data engineeringFrontend and backend developmentQA and testingAIPythonReactAWS

Verdict. Take iTeamly to add Java, React or .NET seniors to your own team. Look elsewhere if you need a documented product track record.

4Soft

Wrocław blockchain and machine learning software house for crypto compliance, analytics and DeFi, with a second office in Dubai.

Clutch: 5.0 (59 reviews)Rate: 50–99 USD/hMin. project: 5,000 USDPremier Verified

Best for: Crypto, DeFi and blockchain compliance products that need smart contracts or analytics from a team that has shipped both for named crypto firms.

Pros

  • 4Soft reported a profit of 501K PLN on 12.2M PLN of revenue in 2024, its latest filing we have.
  • Clutch shows a 5.0 rating from 59 reviews and a Premier Verified badge.
  • The site lists twenty-five case studies, many with named crypto clients such as Elliptic and Cryptio.
  • The site shows ISO 9001 and ISO 27001, which helps buyers with compliance checklists.

Cons

  • Blockchain makes up 90% of the declared work, and the site shows little experience outside crypto.
  • GoWork got 8 positive reviews within 14 days from August 14, 2026, so the employee picture (8 positive, 3 negative) is hard to read.
  • The latest filing we have is for 2024. The site dates the story to 2013, while the S.A. in KRS dates from 2020 after a rebrand.

From their website and Clutch profile

  • The about page dates the story to 2013, while KRS 0000831231 in our data and Clutch's legal formation date point to 2020 for the current entity (source: https://4soft.co/about-us and https://clutch.co/profile/4soft).
  • The home page claims a top 3 position among blockchain companies worldwide without citing a source (source).
  • The home page claims 50+ people, while the 2021 timeline entry mentions 70 experts (source: https://4soft.co/ and https://4soft.co/about-us).
  • Both ISO certificates are downloadable PDFs, which most peers do not offer, but the page names no certifying body (source).
  • The Get an estimate button on the home page links to an empty anchor (source).
  • Clutch lists 59 reviews at 5.0, a $5,000 minimum project and blockchain packages from $4,500 (source).

Clients they name: Elliptic, Cryptio, Colony, Paribus, Gigaset, Artclear

Blockchain development and smart contractsBlockchain analytics and forensicsCrypto compliance (AML screening, KYC flows)Machine learning and AITeam extensionProduct developmentNode.jsPythonBlockchainMachine learning

Verdict. Pick 4Soft for crypto and blockchain compliance work, where its case studies and Clutch reviews can be checked. For a general web product, pick a generalist.

BlueSoft

Warsaw enterprise integrator owned by Orange Polska, focused on data, integration, cloud and AI for banks, telecom and retail.

Clutch: 4.8 (13 reviews)Rate: 50–99 USD/hMin. project: 50,000 USD

Best for: Banks, telecoms and large retailers that need integration, data platforms or managed services from a vendor with a corporate owner.

Pros

  • BlueSoft reported 300.9M PLN of revenue and a profit of 43.8M PLN in 2025.
  • Orange Polska has owned BlueSoft since 2019, which helps with procurement and continuity.
  • Named case studies cover Canal+, Biedronka, GATX and Hellenic Cables. Clutch shows 4.8 from 13 reviews.
  • The job boards showed 72 open roles at the last snapshot.

Cons

  • GoWork employee reviews are negative (13 positive, 39 negative), with 2 mentions of layoffs.
  • The minimum project is 50,000 USD and the processes are enterprise-grade, so an MVP is a poor fit.
  • Many case studies are for Orange companies, the owner, so outside references are fewer than they look.

From their website and Clutch profile

  • BlueSoft has belonged to the Orange Polska group since 2019, together with Craftware and Essembli (source).
  • Several case studies are for Orange companies, the owner, next to clients such as Canal+, Biedronka and GATX (source).
  • The site claims 1000+ experts and 200+ active clients and says it is hiring 118 people (source).
  • The site shows partner logos for AWS, Microsoft, Google, MuleSoft, Salesforce and Databricks (source).

Clients they name: Orange Polska, Canal+, Biedronka, GATX, Hellenic Cables, Raiffeisen Bank

Custom software developmentData platforms and BISystem integration (MuleSoft)Cloud migrationAI agents and document processingManaged servicesJavaPythonTerraformPostgreSQL

Verdict. Pick BlueSoft for corporate integration, data and managed services backed by a telecom group. For a startup or a single small product, it is too heavy.

Droptica

Drupal agency that audits, takes over, migrates and supports mission-critical Drupal platforms for enterprises and public institutions.

Clutch: 5.0 (9 reviews)Rate: 50–99 USD/hMin. project: 5,000 USD

Best for: Organizations with a large Drupal site that need an audit, a Drupal 7 migration or a long-term support team.

Pros

  • Droptica reported a profit of 543K PLN on 12.6M PLN of revenue in 2025.
  • Droptica is a Gold Drupal Certified Partner with 80+ Acquia certifications and its own Drupal distributions.
  • The site has twenty-five named case studies, from PZPN and NATO to Henry Schein.
  • Clutch shows a 5.0 rating from 9 reviews, and the site shows ISO 27001.

Cons

  • Droptica works only on Drupal, so any other stack is a mismatch.
  • Employee reviews lean negative (4 positive, 7 negative), with 2 mentions of layoffs.
  • Clutch shows only 9 reviews, and the job boards had 1 open role at the last snapshot.

From their website and Clutch profile

  • Droptica has 44 people on Drupal.org and 24 maintained projects. It builds the Droopler, Open Intranet and Campus distributions and co-organizes DrupalCamp Poland (source).
  • The partner tier is inconsistent, with Gold Drupal Certified Partner on the homepage and English site and 'Silver' in the agency page text (source).
  • Droptica is one of only two companies in this group with ISO 27001 on the site. Its founding year, 2013, matches the KRS entry (source).
  • The YouTube channel 'Nowoczesny Drupal' posts Polish tutorials and weekly Drupal news. We found no showreel or about-us video (source).
  • Clutch shows 5.0 from 9 reviews, a $5,000 minimum project, $50 to $99 per hour and three Polish locations (source).

Clients they name: PZPN, BOSSA, Exide Group, HERE.com, Henry Schein, Better Regulation

Drupal code auditDrupal support and Care & Growth plansDrupal 7 migration and upgrades to Drupal 11Headless Drupal with React or Next.jsAI features for DrupalMultisite DrupalJavaScriptReactNext.jsPHP

Verdict. Call Droptica first if your platform runs on Drupal, since its client work is public. If it does not, skip it.

Tooploox

AI-first software company (owned by Solvd Inc.) building custom AI, mobile and web products for startups and research-heavy clients.

Clutch: 4.8 (35 reviews)Rate: 50–99 USD/hMin. project: 25,000 USD

Best for: Products where machine learning or generative AI is the core, with a team that publishes research and builds the app around it.

Pros

  • Lists peer-reviewed papers, patents and conference talks on its site, more AI research than any other Wrocław agency.
  • Revenue of 63.8M PLN with a profit of 1.6M PLN in 2025, and named clients such as eBay and ETH Zurich.
  • 4.8 on Clutch from 35 reviews and still hiring AI engineers on the boards (2 open roles).

Cons

  • Owned by Solvd Inc. (USA) since the acquisition, so it is no longer an independent Wrocław company and decisions are made abroad.
  • Employee reviews are negative (13 positive, 22 negative) and 8 of them mention layoffs or cuts; expect rotation on your project.
  • The site gives only an R&D headcount of 40+; the total team size is not stated.

From their website and Clutch profile

  • Tooploox lists 30+ peer-reviewed papers, patents and contributions to NeurIPS, ICML and ECCV, the longest research record in the set (source).
  • Tooploox is now a Solvd Inc. company and no longer an independent Wrocław firm (source).
  • The site gives only an R&D headcount of 40+ engineers and researchers and no total team size (source).
  • No certifications, awards or partner badges are shown on the site (source).

Clients they name: eBay, ETH Zurich, Spire Health, StateSpace, PhotoAid, Ashoka

AI developmentGenerative AIAI discoveryProduct designMobile appsWeb developmentReactNode.jsPythonAI

Verdict. The place in Wrocław for hard AI problems. For a plain web product the research premium buys you little, and the employee reviews are a real warning about continuity.

Synergy Codes

Data visualization and diagramming software agency building custom editors, graph tools and workflow builders for SaaS vendors and enterprises.

Clutch: 4.9 (15 reviews)Rate: 100–149 USD/hMin. project: 5,000 USD

Pros

  • Owned by private individuals (KRS)

Cons

  • Mostly negative employee reviews on GoWork (2 positive, 6 negative)

  • The YouTube channel carries developer tutorials on React Flow and Angular, without a showreel or an about-us video (source).

Clients they name: AMBOSS, peoplefone, Zeenea, Kuberno, Druid, OPAL-RT

Product discovery and product designDiagram and data visualization development (GoJS, React Flow, Yjs, tldraw)UX, performance and code audits for diagram toolsAI proof of concept to productionDesign systems for diagramming productsKnowledge graph and graph editor solutionsTypeScriptReactAIMachine learning

All companies in the data set, with the same score. Companies without a confirmed office, sole traders, body-leasing firms and product companies are listed but not ranked.

Who is not in the top 10, and why

Paid placements and “serves the city” without an office

On the Clutch city list the first positions are bought with ads (links through ppc.clutch.co) or a “serves” entry. These companies have no office in the city according to KRS or their own site, so they are not ranked here.

None in this city.

Struck off the register or in liquidation

They still show up on other people’s “best of” lists. Here they appear only in the full table.

  • Altimi · Wrocław

Body leasing, product companies and other services

Renting people into someone else’s team is a different service from delivering a project. A product company, a marketing agency or an SAP partner does not sell software projects either. They are in the full table with a label.

Too little client evidence, under 10 people, sole traders

Without 5 Clutch reviews or 2M PLN of revenue in a filing there is no fair way to compare a company with the rest. That is a data gap, not a verdict.

What they charge

On Clutch, the JavaScript and TypeScript companies in this data set most often declare 50 to 99 USD an hour. Paid placements and “serves Poland” entries from abroad usually declare 25 to 49 USD. The rate is what the agency bills; the developer on your project is paid less than half of it.

For comparison, my own rate is 36 to 54 USD an hour (45 USD base, pricing). The cost estimator shows what a project like yours costs with and without coding agents.

Rates declared on Clutch, 100 companies with an office in the city. In brackets: companies “serving” the city without an office.

Check any agency yourself in 10 minutes

  1. Find the legal entity in the National Court Register: the seat, the share capital and the shareholders. An office here with a seat in another city is a sales office, not a team.
  2. Read the last financial statement on rejestr.io: revenue, profit or loss, and whether it was filed on time.
  3. Check the VAT white list: active, and the name matches the contract.
  4. On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
  5. On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
  6. Ask who exactly will work on your project, and check those people on LinkedIn.

By clicking Send you agree that I store your request and reply by email; no newsletter. I reply within 24 hours on working days, personally. If I am late, the first hour of work is free.

How this works: I write back with my own offer and forward your brief to the agencies that fit, after you agree. As of October 28, 2026 no agency pays me for leads and this page has no affiliate links. If that changes, it will say so here.

Questions

What are the best JavaScript and TypeScript companies in Poland in 2027?

By the score on this page: 1. Itransition (87), 2. Zaven (87), 3. Intellias (85), 4. Blurify (85), 5. iTeamly (85). The score adds up transparency in the court register, client reviews on Clutch, profit and stability in the latest filing, specialization and current hiring. The full table shows every company checked.

How much do JavaScript and TypeScript companies in Poland charge?

Most declare 50 to 99 USD an hour on Clutch, with minimum projects from 5,000 to 25,000 USD. My own rate as a senior engineer working with AI agents is 36 to 54 USD an hour.

Why is a well-known company not in the ranking?

The full table shows every company with its score. Known names drop when the last filing shows a loss, when Clutch reviews are few, when the Polish entity is too small for the team it claims, or when the company rents people instead of delivering projects.

Did any company pay to be on this list?

No. There are no paid placements and no affiliate links. The only business interest is mine: I sell senior engineering as the alternative to an agency.

How often is the data updated?

Every entry shows the date each source was checked. The plan is a full refresh every quarter.

Can I get my company added or corrected?

Yes. Write to ciunkos@gmail.com with the KRS number and the correction.

How this ranking was made

  • 1,485companies in the data set
  • 709checked in the National Court Register
  • 454with a financial statement
  • 7,436Clutch listing positions read, paid ones marked
  • 451employee review profiles on GoWork
  • 2+months of data collection, since September 2026

The company list comes from a full read of the Clutch city listing (every page, with paid positions marked by their ppc.clutch.co links), the ITCORNER cluster, Google results and job ads. Every company was checked in the National Court Register (KRS) for its seat, legal form, capital and shareholders, in rejestr.io for revenue and profit from the latest filing, on GoWork for employee sentiment, layoff mentions and review clusters, and on the JustJoin.it and No Fluff Jobs boards for open roles and the stack they actually pay for. The 0 to 100 score is five axes with published weights: transparency, client reputation, stability, specialization, activity. A paid Clutch placement does not raise the score.

Disclosures

  • I worked at Sanddev (Wrocław) as the founding engineer of its Sandtime product until November 2026. Sanddev appears in the full table with the same score as everyone else and no editorial favor.
  • As a contractor I have talked with, or applied to, some of the agencies on these lists. None of them knew about this ranking and none of it changed a score.
  • No agency pays for a position, there are no affiliate links, and no company has seen its entry before publication. If any of that changes, the disclosure changes first.
  • My business interest is on every page: I sell senior engineering with AI agents as the alternative to hiring an agency.
  • Written with AI (Claude) from the data set. Every number in the editorial text is checked automatically against the company record or the research notes, and every top entry was read against the company’s own website. Sources and check dates are under each entry.
