Hey HN

I built AI Review https://github.com/Nikita-Filonov/ai-review — an open-source AI-powered code review tool that runs directly inside your CI/CD and works with any LLM provider. It adds inline comments, summary reviews, and even assistant-style replies directly into your Pull/Merge Requests — and you can set it up in about 15–30 minutes.

The key idea: AI Review is not a SaaS. It doesn't send your code anywhere and isn't tied to any vendor. You can run it:

- Locally via Ollama — no tokens, no VPN, no data leaves your infra - With OpenAI, Claude, Gemini, or your own inference server - On any CI/CD (GitHub, GitLab, Bitbucket, Jenkins, etc.) - As a CLI tool, Docker image, or GitHub Action

A minimal GitLab CI job looks like this:

ai-review: image: nikitafilonov/ai-review:latest script: - ai-review run variables: LLM__PROVIDER: "OPENAI" LLM__META__MODEL: "gpt-4o-mini" VCS__PROVIDER: "GITLAB" VCS__PIPELINE__MERGE_REQUEST_ID: "$CI_MERGE_REQUEST_IID"

It supports 9 diff modes, fully customizable prompts, system-level review contracts, and artifacts for debugging. Reviews for medium-sized MRs typically complete in ~20–40s.
