I'm Jay, co-creator of Mira. An open-source, self-hosted AI code reviewer where you BYOK (bring your own key).

Local models are getting really good.

Hosted frontier models are getting really expensive.

So, we built Mira. Mira has some snazzy features too:

- It's really fast at reviewing. Average is 77s compared with Greptile's 5 minutes. Your PRs aren't going into a queue on a cloud somewhere.

- Mira performs a blast radius and see what damage will be done with code change.

- Learns your codebase's patterns from the repo itself and enforces them without a config file.

- It's self-hosted, so your code never leaves your infrastructure. Bring your own model - OpenAI, Anthropic, or a local LLM behind your firewall.

We're really active, and looking for active contributors. Come join us in our discord!
