In their own words
Mira
Mira is a free, open-source AI code reviewer for pull and merge requests. It indexes repositories, using project context beyond the changed diff when assessing changes. Review results include inline comments with severity and confidence, plus a pull-request walkthrough and summary. GitHub users can apply one-click suggestions. Security analysis combines model-based review with secret scanning and OSV checks for packages added or upgraded in a request. Mira can learn custom review rules from rejected comments and recurring feedback on merged requests. It supports GitHub, GitLab, Forgejo, and Codeberg; Bitbucket support is planned. Operators deploy Mira themselves as a Docker image, storing indexes in SQLite or Postgres. Requests are routed through OpenRouter, with provider choices including Anthropic, OpenAI, Google, and DeepSeek. The maker says self-hosted deployments send no data or telemetry to its infrastructure. The source is available under Apache 2.0. The free plan includes all features; users pay model-provider costs directly.
