By GitHub stars it is Grok Build, with 27,764 stars and a commit on 29 Sep. Choose Grok Build when you want a terminal coding agent whose source you can read and build yourself under Apache 2.0, on xAI's Grok models. Next come Mistral Vibe CLI (5,385 stars).

Yes. The code of all 2 is public under Apache 2.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.

1 of the 2 we track had a commit in the last 30 days, among them Mistral Vibe CLI. The quietest is Grok Build, last changed on 29 Sep. A recent commit shows the project is kept up, not that it will stay that way.

Apache 2.0 (2). MIT, BSD and Apache let you change and reuse the code freely.

The hosting. Muse Code's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
