Missed the latest GitHub check; these facts may be older.

Overview

Probot-based GitHub app that reviews pull requests with OpenAI-compatible models and posts comments in the PR timeline and file changes. It re-reviews changed files after each push. It runs as a GitHub Action, a self-hosted Node app under pm2, or a Docker container, and supports OpenAI, Azure deployments and GitHub Models.

Who it is for: Teams on GitHub wanting automated LLM review comments on pull requests

Strengths

  • Runs as a GitHub Action with a short workflow file, or as a self-hosted Probot app
  • Supports OpenAI endpoints, Azure deployments and GitHub Models
  • Filters files with IGNORE_PATTERNS and INCLUDE_PATTERNS; skips diffs over MAX_PATCH_LENGTH
  • Review language, prompt, temperature and max_tokens set through environment variables

Weaknesses

  • Hosted bot is test-only and rate-limited on AWS Lambda; README advises self-deploying
  • Sends diffs to an external LLM API, so an API key and usage cost are required
  • GitHub only; no GitLab or other platform support mentioned
  • Docker section lists no exposed port or full env list; relies on .env.example

What it needs

  • no GPU
  • Docker
  • Needs GitHub App or GitHub Actions, OpenAI-compatible API, Azure OpenAI or GitHub Models, Node.js, pm2 (self-hosting)
  • Models: OpenAI GPT models, Azure OpenAI deployments, GitHub Models
