Mira

Code review, at the speed of merge.·miracode.ai

Free plan · Open source See pricing ↓

Mira is an open-source, self-hostable AI code reviewer that watches pull and merge requests on GitHub, GitLab, or Forgejo and posts inline comments and PR walkthroughs. It indexes the whole codebase to reason about bugs, security issues, and style/convention drift, using an LLM the user brings themselves (Anthropic, OpenAI, Google, DeepSeek, or any model via OpenRouter). The full review engine, indexing, custom rules, dashboard, and learning loop are included at no cost, with no paid tier.

What it's for

Automatically review pull requests for bugs and regressionsDetect security vulnerabilities like injection and leaked secretsEnforce codebase style and conventions without a config fileGenerate human-readable PR summaries and walkthroughsAssess blast radius of changes across dependent repositoriesProvide inline one-click fix suggestions
