It's so lean you can use it for free!
When your subscription runs out, or you don't have one, keep vibecoding with 3code. There are many open-weight model providers, some of them free. 3code gives you a nice, familiar interface and special tuning so you can use them for coding.

3code, the economical coding agent is as useful as any top coding agent, but also takes special care not to burn any more tokens, computer power or brain cycles than it absolutely needs to.
We eat our own dog food! 3code is to a large extent written in 3code. Right now we use GLM 5.1 on the z.ai coding plan.
Can't do anything about token burn that's needed- but a lot of it isn't needed, and 3code doesn't do that.
It's a chat program. It shouldn't use a lot of power on your computer, and it doesn't.
No one wants to save tokens by having to do everything by hand, and having ones cake and eating it too is our core value- so we're clever about still achieving convenience!
3code measured from release binary. opencode and goose from release artifacts. *claude code has no standalone binary; figure includes the Node.js runtime it requires.
Benchmarks ongoing - explorative dogfooding suggests 30-50% token savings.
