The top Node.js development companies in 2026 fall into three groups: ecosystem specialists whose engineers help maintain Node.js and its key frameworks, such as NearForm and Platformatic; official OpenJS Foundation partners for end-of-life support and upgrades, HeroDevs, NodeSource and Codemod; and consulting and product development firms that build Node.js backends day to day. Whichever you hire, ask which Node.js version they will use: Node.js 20 reached end of life on April 30, 2026, and Node.js 26 became an LTS release on October 28, 2026.
Key Takeaways
- Node.js 20 stopped receiving security fixes on April 30, 2026. Node.js 24 moved to Maintenance LTS on October 20, 2026, and Node.js 26 entered Active LTS on October 28, 2026.
- The Node.js project names HeroDevs and NodeSource as its commercial partners for security fixes on end-of-life versions, and NodeSource is the first partner in OpenJS’s Node.js LTS Upgrade and Modernization program.
- OpenJS data shows roughly two-thirds of Node.js users run unsupported or outdated versions.
- NearForm and Platformatic are closely linked to the people who maintain Node.js, Fastify and Pino, which matters for performance and architecture work.
- Most “Node.js companies” sell full-stack software generally. Test backend depth with four specific questions before you shortlist.
- Every Node.js codebase needs a major upgrade roughly every one to two years; price that into the contract, not after the fact.

Why Choosing a Node.js Company Is a Maintenance Decision
Node.js runs on a fixed release schedule, and each version stops receiving security fixes on a published date. Any competent firm can build an API in Node.js; the difference between firms shows up over the following years, when the runtime version under that API reaches end of life.
The scale of the problem is large. NodeSource’s download analysis reports that Node.js 20 still accounted for more than 103 million downloads in 2026 despite reaching end of life on April 30, 2026, with Node.js 18 having reached end of life a year earlier. When OpenJS launched its upgrade program in March 2026, it cited its own data showing that roughly two-thirds of Node.js users run unsupported or outdated versions. A good Node.js partner tells you which version it will build on, when that version expires and what the upgrade will cost.
Which Node.js Versions Matter in Late October 2026?
Node.js versions move through three phases: Current, Active LTS and Maintenance LTS. The official Node.js releases page now lists Node.js 26, 24 and 22 as LTS, Node.js 20 as end of life, and Node.js 27 as an alpha release first published on October 29, 2026. The Node.js release blog shows Node.js 26.13.0 published as an LTS release on October 28, 2026.
| Release line | Status on October 30, 2026 | End of life |
| Node.js 26 | Active LTS since October 28, 2026 | April 30, 2029 |
| Node.js 24 (Krypton) | Maintenance LTS since October 20, 2026 | April 30, 2028 |
| Node.js 22 (Jod) | Maintenance LTS | April 30, 2027 |
| Node.js 20 (Iron) | End of life | April 30, 2026 |
Sources: Node.js releases page, Node.js release blog and the Node.js release schedule. For a new production build, Node.js 26 or 24 is the sensible target; Node.js 22 suits existing codebases only until April 2027.
The release model is also changing. The Node.js project announced that from October 2026 it moves to one major release a year, released in April and promoted to LTS in October, and that every release will become LTS. Node.js 26 is the last line under the old model and reaches end of life in April 2029; Node.js 27 enters LTS in October 2027 and reaches end of life in April 2030.
How We Chose These Companies
Most “top Node.js companies” lists sort agencies by review-site ratings, which barely differ between established firms. We used evidence tied to the Node.js project itself:
Official recognition by the Node.js project or OpenJS Foundation, such as the commercial partners named on nodejs.org, partners in OpenJS programs, or OpenJS membership for consulting firms.
Documented links to Node.js core or its major frameworks, such as Technical Steering Committee membership or maintainer roles on Fastify.
Companies are grouped by what they do best and listed alphabetically within each group.
About the publisher: AB Ark Solutions publishes this article and also builds Node.js backends. We have included AB Ark in its own section, clearly marked, so readers can assess it with the same questions as every other firm.

Node.js Ecosystem Specialists
NearForm: best for hard backend engineering and performance
NearForm is a professional services firm with deep roots in the Node.js community. Its staff have included core contributors to Fastify, one of the main Node.js web frameworks: the authors of Packt’s Fastify book include a NearForm senior backend developer who is a core Fastify maintainer. Earlier Node.js books describe NearForm as a consultancy specialising in enterprise digital transformation on Node.js. NearForm also represented Silver members on the OpenJS Foundation board in 2023. It suits performance-critical systems, complex architecture and teams that need senior Node.js expertise.
Platformatic: best for Node.js platform engineering
Platformatic was co-founded by Matteo Collina, who is listed as a member of the Node.js Technical Steering Committee and lead maintainer of Fastify, and who previously served as Chief Software Architect at NearForm. Platformatic builds tooling to remove friction from Node.js backend development. It suits organisations running Node.js at scale that need deep runtime and architecture expertise rather than general feature delivery.
Official End-of-Life Support Partners
The Node.js end-of-life page states that, through the OpenJS Foundation’s Ecosystem Sustainability Program, Node.js is supported by HeroDevs and NodeSource to provide commercial security fixes. The OpenJS Foundation launched the program so that partners would share revenue with OpenJS projects in return for supporting archived and end-of-life versions.
HeroDevs: best for security fixes on end-of-life Node.js
HeroDevs was the first partner in the program and offers Node.js Never-Ending Support for versions past their official end of life. It is a Gold member of the OpenJS Foundation. The Node.js project’s own announcement on Node.js 18 points teams that cannot upgrade to this service.
NodeSource: best for upgrading off end-of-life Node.js
NodeSource was added to nodejs.org as a second ESP partner alongside HeroDevs, providing commercial support for end-of-life Node.js versions. In March 2026, OpenJS launched its Node.js LTS Upgrade and Modernization program with NodeSource as the first partner. Approved partners assess versions and dependencies, manage phased upgrades to supported LTS releases and offer temporary security support when an immediate upgrade is not possible. OpenJS requires program partners to be Gold members and to demonstrate Node.js modernization expertise. NodeSource says its upgrade assessment is free and its Expert Strategy Blueprint starts at $2,499.
Codemod: best for automating code changes during upgrades
The OpenJS Foundation announced that Codemod became an OpenJS partner to simplify Node.js migrations. Codemod is a tooling company rather than a development agency, so it fits teams whose own engineers or development partner will run the upgrade with automated code transformations.
Extended support is a bridge, not a destination. Use it to stay secure while a development partner upgrades your application to a supported line.
Consulting and Delivery Firms
Greyshore Associates: best for consulting and delivery on JavaScript projects
The OpenJS Foundation welcomed Greyshore Associates as a member in February 2024, describing it as a network of experienced technologists providing consulting and delivery services. Membership signals investment in the JavaScript ecosystem; ask for Node.js-specific case studies before shortlisting.
Also Consider: AB Ark Solutions (Publisher of This Article)
AB Ark Solutions offers dedicated Node.js developers and builds backends and APIs for web and SaaS products, often alongside AI agent development. It has offices in Dubai, UAE; Lewes, Delaware, US; and Lahore, Pakistan. Its published case studies include AI products such as a 24/7 AI call agent platform that answers calls and manages bookings across multiple business branches, and an AI voice assistant for UCLODIA that AB Ark reports lifted visitor conversion from 2.4% to 8.1%.
AB Ark suits startups and growing companies that want Node.js delivery at offshore rates and one team responsible for both the backend and the AI layer. As with any firm, ask AB Ark which LTS line it will target and how it handles the next major upgrade.
How Do You Tell a Node.js Specialist From a Generalist?
Many firms list Node.js among dozens of technologies. Four questions reveal real backend depth:
Which LTS line will you use, and why? In late October 2026, Node.js 26 or 24 for new work, with an upgrade date written into the plan.
Which framework will you use? Express, Fastify and NestJS suit different needs; a specialist explains the trade-off.
How do you find performance problems in production? Look for real experience with profiling, diagnostics, tracing and load testing.
Who handles the next major upgrade, and how is it priced? Every Node.js codebase needs one roughly every one to two years.
What Does Node.js Development Cost in 2026?
Node.js development cost depends on region, seniority and scope. Accelerance’s 2026 survey puts senior developer partner rates at about $31 to $41 an hour in Asia, $60 to $75 in Latin America and $64 to $76 in Central and Eastern Europe, with US firms typically higher. Ecosystem specialists usually charge at the top of their regional range for senior expertise.
Two costs are often left out of quotes: the major-version upgrade, and observability tooling for production. Ask for both in writing.

Common Mistakes When Hiring a Node.js Company
Leaving the Node.js version unspecified: name the LTS line in the contract, or you inherit whatever was convenient.
Treating ratings as a ranking: most established firms score near the top of review scales.
Buying breadth when you need depth: a firm with many service lines may be excellent but not a backend specialist.
Ignoring end-of-life systems: a running app on Node.js 20 or older needs an upgrade plan or extended support now.
Forgetting the upgrade cycle: plan and budget for major upgrades from day one.
FAQs
Which are the top Node.js development companies in 2026?
For ecosystem depth, NearForm and Platformatic. For end-of-life support and upgrades, HeroDevs and NodeSource, the partners named by the Node.js project, plus Codemod for automated migrations. For general product development, choose a firm that passes the four specialist questions and names its LTS target in writing.
Which Node.js version should a new project use?
Node.js 26, which became an LTS release on October 28, 2026, or Node.js 24, supported until April 30, 2028. Avoid starting new work on Node.js 22, which reaches end of life in April 2027.
Is Node.js 20 still safe to run?
No. Node.js 20 reached end of life on April 30, 2026 and receives no security fixes. Upgrade with help from a partner such as NodeSource, or use extended support from HeroDevs or NodeSource while you migrate.
What is the OpenJS Ecosystem Sustainability Program?
An OpenJS Foundation program in which commercial partners provide security fixes for end-of-life versions of OpenJS projects such as Node.js and share revenue with those projects.
How much does it cost to hire a Node.js development company?
Senior partner rates in 2026 range from about $31 to $41 an hour in Asia to $60 to $76 in Latin America and Central and Eastern Europe, with US firms higher. Include upgrade and observability work in the estimate.
Choose a Node.js partner for the whole life of your backend, not just the first release: name the LTS line, plan the upgrades, and match the company to the job.
