---

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)

Add automated PR reviews to your repository with a simple workflow file:

# .github/workflows/pr-agent.yml
name: PR Agent
on:
  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 GitHub Action setup guide

2. CLI Usage (Local Development)

Run PR-Agent locally on your repository:

pip install "pr-agent[github]"
export OPENAI_KEY=your_key_here
pr-agent --pr_url https://github.com/owner/repo/pull/123 review

Git provider SDKs are optional extras: install the one for your provider (list), or pr-agent[all] for every integration. Complete CLI setup guide

3. Other Platforms

• GitLab webhook setup
• BitBucket app installation
• Azure DevOps setup

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

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
/review
/improve
/ask "What does this PR change?" # free-text Q&A about the PR

# Issue-scoped commands run on an issue instead of a PR:
/similar_issue # find similar issues in the repository

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

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

Data Privacy

Self-hosted PR-Agent

• If you host PR-Agent with your OpenAI API key, it is between you and OpenAI. You can read their API data privacy policy here: https://openai.com/enterprise-privacy

Contributing

To contribute to the project, get started by reading our Contributing Guide.

For local verification, run PYTHONPATH=. uv run pytest from the repository root; it discovers the unit-test suite under tests/unittest by default. End-to-end tests under tests/e2e_tests require provider credentials and should be invoked explicitly, for example PYTHONPATH=. uv run pytest tests/e2e_tests/test_github_app.py.

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.
