AI code review that runs inside your pull requests, follows rules you write in plain language and uses your own model keys.
Kodus puts an AI reviewer called Kody directly into the pull request, where it reviews with context, flags risks by severity and suggests concrete fixes rather than summarizing the diff. The README walks through it catching an IDOR risk where an organization id passed as an array could bypass tenant protection.
It is model agnostic. Claude, GPT-5, Gemini, Llama, GLM, Kimi or any OpenAI-compatible endpoint connects with your own provider credentials, so billing stays on your account with no markup on model costs. It works natively with GitHub, GitLab, Bitbucket and Azure Repos, and runs from a CLI locally or inside a pipeline.
Several pieces sit around the review itself.
- Kody Rules: review instructions written in plain language and scoped to an organization, repository, path or review type.
- Kody Issues: unimplemented suggestions from closed pull requests are tracked by status, severity and category, then resolved when a later PR fixes them.
- Cockpit: review effectiveness, rule health, repository health and delivery metrics in one dashboard.
- Token usage: consumption is tracked across reviews so model spend stays predictable as adoption grows.
- Privacy: source code is not used to train models, and data is encrypted in transit and at rest.
The project is AGPLv3 licensed, with documentation in six languages. Self-hosted instances send one anonymous daily heartbeat of aggregated counters, with no code, names or identifiers, and an environment variable turns it off. Self-hosted runners suit teams who cannot send source code outward, while a managed cloud covers anyone who would rather not deploy anything at all.
