The Original Open-Source PR Reviewer

This repository contains the open-source PR Agent Project. It is not the Qodo offering for open-source projects.

PR-Agent is an open-source, AI-powered code review agent and a community-maintained legacy project of Qodo. It is distinct from Qodo's primary AI code review offering, which provides a feature-rich, context-aware experience. Qodo offers a free version for open-source projects and integrates seamlessly with GitHub, GitLab, Bitbucket, and Azure DevOps for high-quality automated reviews.

Sponsors

PR-Agent is a community-maintained open-source project, with its ongoing development supported by our sponsors. If you'd like to support the project, consider becoming a sponsor.

Getting Started

[!NOTE] Docker Hub namespace migration. Releases 0.34.2 and later are published under pragent/pr-agent. Older releases (up to and including v0.31) remain available at the legacy codiumai/pr-agent namespace as a frozen archive — no new images are pushed there. Update any pinned image: / docker pull / uses: docker:// references when upgrading to 0.34.2+.

🚀 Quick Start for PR-Agent

1. GitHub Action (Recommended)

name: PR Agent

  pull_request:
    types: [opened, synchronize]
jobs:
  pr_agent_job:
    runs-on: ubuntu-latest
    steps:
    - name: PR Agent action step
      uses: the-pr-agent/pr-agent@main
      env:
        OPENAI_KEY: ${{ secrets.OPENAI_KEY }}
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Full notes for every release are on the Releases page.

Jul 26, 2026 — v0.41.0

Claude Opus 5 support, and docker/mosaico became a self-contained deployment bundle.

Jul 25, 2026 — v0.40.0

Default model moved to GPT-5.6, Gemini 3.6 support, persistent inline comments (no more duplicate suggestions across runs), an OpenRouter provider-routing/reasoning config, a tokenless plain-diff provider, and CI artifact context injection.

Jul 5, 2026 — v0.39.0

AGENTS.md and friends are now fed to /review, /describe and /improve by default, so the model picks up your project's conventions out of the box. Also: Agent Skills (SKILL.md), organization-level settings, restricted mode for reduced GitHub permissions, GitHub Checks as an output target, and Claude Sonnet 5 support.

Why Use PR-Agent?

🎯 Built for Real Development Teams

Fast & Affordable: Each tool (/review, /improve, /ask) uses a single LLM call (~30 seconds, low cost)

Handles Any PR Size: Our PR Compression strategy effectively processes both small and large PRs

Highly Customizable: JSON-based prompting allows easy customization of review categories and behavior via configuration files

Platform Agnostic:

• Git Providers: GitHub, GitLab, BitBucket, Azure DevOps, Gitea
• Deployment: CLI, GitHub Actions, Docker, self-hosted, webhooks
• AI Models: OpenAI GPT, Anthropic Claude, Google Gemini, DeepSeek, Mistral, and any other model reachable through LiteLLM (Azure OpenAI, AWS Bedrock, Vertex AI, Databricks, OpenRouter, Ollama, and more) — see Changing a model

Open Source Benefits:

• Full control over your data and infrastructure
• Customize prompts and behavior for your team's needs
• No vendor lock-in
• Community-driven development

Features

/describe

/review

/improve

Usage Examples

PR-Agent tools run as a comment on a PR or from the CLI. A few common ones:

# Comment on a PR (GitHub/GitLab/Bitbucket/…):
/describe                        # generate title, summary, walkthrough and labels
/review                          # findings, security, review effort and tests
/improve                         # actionable code-improvement suggestions
/ask "What does this PR change?" # free-text Q&A about the PR

# Or locally via the CLI:
pr-agent --pr_url <PR_URL> review

See the Tools docs for the full list of tools with example commands, and each tool's page for screenshots and options.

Big News for PR-Agent

PR-Agent has a new home!

After years of building this tool alongside the community, Qodo has donated PR-Agent to the open-source community - and we couldn't be more excited about what comes next.

The project now lives in the PR-Agent org on GitHub, is fully community-owned, and is open for contributions and additional maintainers.

What else changed:

• Docs moved to - docs.pr-agent.ai
• Qodo Merge (Qodo 1.0), the hosted URL, which was the enterprise version of PR-Agent, has been rebranded and evolved into Qodo (Qodo 2.0), a full AI code review platform.

❤️ Community

This open-source release remains here as a community contribution from Qodo — the origin of modern AI-powered code collaboration. We’re proud to share it and inspire developers worldwide.

The project now has its first external maintainer, Naor (@naorpeled), and is currently in the process of being donated to an open-source foundation.
