What are the best Rust AI agents?

By maintained adoption — GitHub stars plus recent commit activity — Zed, openinterpreter and goose lead the Rust AI agents in this index of 14. The full ranking is below; it reflects what is genuinely used and still maintained, not what pays.

Are these Rust AI agents open source and free?

Yes — every project on this page is open source and written primarily in Rust. Apache-2.0 is the most common licence here, on 4 of 14, across 6 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 Rust AI agents specifically?

Staying in your team's primary language — Rust — 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: 13 of these 14 shipped in the last 90 days, and reading a quiet project's source is how you tell finished from abandoned.

Best Rust AI agents

The 14 open-source AI agents written in Rust in this index, ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. Zed leads the set at 90,999 GitHub stars, and 13 of the 14 have shipped a commit in the last 90 days. Every project here is Rust-first, self-hostable, and free to run; the trade-off is you host and maintain it yourself. Right now it's led by Zed (91k stars), with openinterpreter and goose close behind. Rankings shift as projects gain stars and ship commits.
