Best JavaScript AI agents

The open-source AI agents written in JavaScript, from the Agent Search Engine index — ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. Every project here is JavaScript-first, self-hostable, and free to run; the trade-off is you host and maintain it yourself. Right now it's led by anything-llm (65k stars), with xiaozhi-esp32-server and evolver close behind. Rankings shift as projects gain stars and ship commits.

Frequently asked

What are the best JavaScript AI agents?
The JavaScript projects listed below, ranked by maintained adoption — GitHub stars plus recent commit activity — so you see what's genuinely used and still maintained, not abandoned.
Are these JavaScript AI agents open source and free?
Yes — every project on this page is open source and written primarily in JavaScript. 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 JavaScript AI agents specifically?
Staying in your team's primary language — JavaScript — 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.
