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.

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.
