Best TypeScript AI agents
The 121 open-source AI agents written in TypeScript in this index, ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. n8n leads the set at 206,196 GitHub stars, and 97 of the 121 have shipped a commit in the last 90 days. Every project here is TypeScript-first, self-hostable, and free to run; the trade-off is you host and maintain it yourself. Right now it's led by n8n (206k stars), with firecrawl and dify close behind. Rankings shift as projects gain stars and ship commits.

Frequently asked
- What are the best TypeScript AI agents?
- By maintained adoption — GitHub stars plus recent commit activity — n8n, firecrawl and dify lead the TypeScript AI agents in this index of 121. The full ranking is below; it reflects what is genuinely used and still maintained, not what pays.
- Are these TypeScript AI agents open source and free?
- Yes — every project on this page is open source and written primarily in TypeScript. MIT is the most common licence here, on 69 of 121, across 8 licences in total. The software is free to run and self-host; you still pay for the infrastructure you run it on and any model or API usage it makes.
- Why choose TypeScript AI agents specifically?
- Staying in your team's primary language — TypeScript — makes self-hosting, extending, and debugging far easier, because you can read and modify the source directly instead of treating it as a black box. It also makes upstream activity something you can judge: 97 of these 121 shipped in the last 90 days, and reading a quiet project's source is how you tell finished from abandoned.
