AI code review that refuses to mark up your LLM bill
Kodus is an open-source AI code reviewer that plugs into PRs and lets you bring your own LLM keys, cutting out the SaaS markup.

What it does Kodus reviews pull requests on GitHub, GitLab, Bitbucket, and Azure Repos using whichever LLM you supply—Claude, GPT-5, Gemini, Llama, or any OpenAI-compatible endpoint. You pay the model provider directly; the project takes no markup. It also tracks technical debt and delivery metrics, and adapts its feedback to your codebase over time via a “Kody” learning layer.
The interesting bit Kodus treats LLM access like a utility you pay directly rather than a bundled SaaS upsell. The AGPL-licensed core can be self-hosted entirely, with encrypted data handling and an explicit promise that source code is not used to train models.
Key highlights
- Bring-your-own-key for unlimited PR reviews on the free Community tier
- Plain-language custom review rules (“Kody Rules”) and context-aware memory
- CLI and CI/CD integration for local or pipeline-based reviews
- Monorepo architecture: separate
apps/api,apps/webhooks,apps/worker, andapps/webservices - Anonymous daily heartbeat on self-hosted instances, opt-out via
KODUS_TELEMETRY_DISABLED
Caveats
- Several premium features—SSO, RBAC, audit logs, and an engineering metrics cockpit—are reserved for paid Teams and Enterprise tiers
- The README’s feature comparison table lists some items as “Not listed on card” for paid tiers, which makes the exact Community/Teams boundary slightly unclear
- Enterprise tier oddly drops BYOK support, requiring use of a “Kodus AI Tokens API key” instead
Verdict Teams that want AI review without surrendering model choice or paying a SaaS markup on tokens should look here; developers wanting a fully managed AI coding suite with no API key management may find the BYOK setup extra work.
