Robin Review review
A free self-hosted GitHub reviewer with flexible LLM options and a narrow scope.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Robin Review is an open-source AI code review tool for GitHub pull requests. It runs as a GitHub Actions workflow inside the repository and posts pull-request summaries, severity tiers and inline comments on changed lines. Developers, open-source maintainers and teams can use it with public or private repositories when they want repository-local review automation rather than a vendor-hosted review service or per-seat subscription. Its self-hosted model also suits teams that want to provide their own LLM API key.
The published Free plan costs 0 USD as a one-time price and is MIT-licensed, with no per-seat pricing and no review quota. Bring-your-own-key support works with OpenAI-compatible endpoints, including OpenAI, Azure OpenAI, Groq, OpenRouter and Ollama. The product can review automatically when a pull request opens, run an on-demand re-review through the /robin comment command, and produce a short summary through /summary. LLM provider usage may incur separate token costs, so the overall expense depends partly on the selected provider and endpoint.
GitHub Actions installation, fork pull-request support and maintainer-triggered reviews give Robin Review a focused fit for GitHub-centered workflows. Its scope is narrower than code review products that include verified custom rules, security analysis or analytics, and it supports GitHub rather than multiple code hosts. Teams seeking a free, open-source reviewer with provider choice and repository-local execution should consider it. Teams needing broader platform coverage, deeper security analysis, analytics or verified rule customization should choose an alternative.
