# 🧠 PR Agent LEGACY STATUS (open source)
Originally created and open-sourced by Qodo - the team behind next-generation AI Code Review.
<div align="center">
## 🚀 About
PR Agent was the first AI assistant for pull requests, built by Qodo, and contributed to the open-source community.
It represents the first generation of intelligent code review - the project that started Qodo’s journey toward fully AI-driven development, Code Review.
If you enjoy this project, you’ll love the next-level PR Agent - Qodo free tier version, which is faster, smarter, and built for today’s workflows.

## Open-Source AI-Powered Code Review Tool
**PR-Agent** is an open-source, AI-powered code review agent. It is the legacy project from which Qodo Merge 💎, a separate commercial product, originated. PR-Agent is maintained by the community as a gift to the community. We are looking for additional maintainers to help shape its future; please contact us if you are interested.
**[Qodo Merge](https://qodo-merge-docs.qodo.ai/overview/pr_agent_pro/) 💎** is a separate, enterprise-grade product with its own distinct features, zero-setup, and priority support.
If you have an open-source project, you can get the Qodo paid version for free for your project, powered by Google Gemini 2.5 Pro – [https://www.qodo.ai/solutions/open-source/](https://www.qodo.ai/solutions/open-source/)

### 💬 PR Chat Interface
Lets you converse with your PR to explain, summarize, or suggest improvements instantly.
## PR-Agent vs Qodo Merge
PR-Agent and Qodo Merge are now two completely different products that share a common history. PR-Agent is the original, legacy open-source project. Qodo Merge was initially built upon PR-Agent but has since evolved into a distinct product with a different feature set.
### PR-Agent (This Repository) - Open Source
✅ **What you get:**
- Complete source code access and customization
- Self-hosted deployment options
- Core AI review tools (`/describe`, `/review`, `/improve`, `/ask`)
- Support for GitHub, GitLab, BitBucket, Azure DevOps
- CLI usage for local development
- Free forever
⚙️ **What you need to manage:**
- Your own API keys (OpenAI, Claude, etc.)
- Infrastructure and hosting
- Updates and maintenance
- Configuration management
### Qodo Merge - A Separate Product
✅ **What you get (everything above plus):**
- Zero-setup installation (2-minute GitHub app install)
- Managed infrastructure and automatic updates
- Advanced features: CI feedback, code suggestions tracking, compliance (rules), custom prompts, and more
- Priority support and feature requests
- Enhanced privacy with zero data retention
- Free tier: 75 PR reviews/month per organization
💰 **Pricing:**
- Free tier available
- Paid plans for unlimited usage
- [View pricing details](https://www.qodo.ai/pricing/)
**👨‍💻 Developer Recommendation:** Start with PR-Agent if you want to experiment, customize heavily, or have specific self-hosting requirements. Choose Qodo Merge if you want to focus on coding rather than tool maintenance.

## Try It Now
Try the GPT-5 powered PR-Agent instantly on _your public GitHub repository_. Just mention `@CodiumAI-Agent` and add the desired command in any PR comment. The agent will generate a response based on your command.
For example, add a comment to any pull request with the following text:
```
@CodiumAI-Agent /review
```
and the agent will respond with a review of your PR.
Note that this is a promotional bot, suitable only for initial experimentation.
It does not have 'edit' access to your repo, for example, so it cannot update the PR description or add labels (`@CodiumAI-Agent /describe` will publish PR description as a comment). In addition, the bot cannot be used on private repositories, as it does not have access to the files there.

## Qodo Merge 💎

**Enhanced Privacy:**
- Zero data retention policy
- No data used for model training
- Enterprise-grade security
**Additional Features:**
- Advanced code suggestions with tracking
- CI feedback analysis
- Custom prompts and labels
- Static code analysis integration
- Priority support
**Pricing:**
- Free tier: 75 PR reviews/month per organization
- Paid plans for unlimited usage
- Free for open source projects
See [complete feature comparison](https://qodo-merge-docs.qodo.ai/overview/pr_agent_pro/) for detailed differences.
## How It Works
The following diagram illustrates PR-Agent tools and their flow:
![PR-Agent Tools](https://www.qodo.ai/images/pr_agent/diagram-v0.9.png)
Check out the [PR Compression strategy](https://qodo-merge-docs.qodo.ai/core-abilities/#pr-compression-strategy) page for more details on how we convert a code diff to a manageable LLM prompt
## 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
### Qodo-hosted Qodo Merge 💎
- When using Qodo Merge 💎, hosted by Qodo, we will not store any of your data, nor will we use it for training. You will also benefit from an OpenAI account with zero data retention.
- For certain clients, Qodo-hosted Qodo Merge will use Qodo’s proprietary models — if this is the case, you will be notified.
- No passive collection of Code and Pull Requests’ data — Qodo Merge will be active only when you invoke it, and it will then extract and analyze only data relevant to the executed command and queried pull request.
### Qodo Merge Chrome extension
- The [Qodo Merge Chrome extension](https://chromewebstore.google.com/detail/qodo-merge-ai-powered-cod/ephlnjeghhogofkifjloamocljapahnl) serves solely to modify the visual appearance of a GitHub PR screen. It does not transmit any user's repo or pull request code. Code is only sent for processing when a user submits a GitHub comment that activates a PR-Agent tool, in accordance with the standard privacy policy of Qodo-Merge.
