ThinkReview Goes Open Source: Accelerating AI Code Review Innovation Together

ThinkReview Goes Open Source: Accelerating AI Code Review Innovation Together

Today marks a significant milestone in ThinkReview's journey. After months of development and serving 128+ developers with a 5.0★ rating, we're excited to announce that ThinkReview is now open source!

---

🎉 A New Chapter Begins

We're thrilled to announce that ThinkReview is now open source! The source code for our AI-powered code review browser extension for GitLab and Azure DevOps is now available under the AGPL-3.0 license.

This isn't just about publishing code—it's about inviting the developer community to join us in making code reviews better for everyone.

---

📊 What We've Built So Far

Since launching on the Chrome Web Store, ThinkReview has achieved:

- ⭐ 5.0/5 rating - Validated by real users
- 🏆 Featured by Chrome Web Store - Recognized for quality
- ✅ Good publisher record - Trusted by Chrome
- 📜 Follows recommended practices - Built with best standards

But numbers only tell part of the story. What matters most is that developers are using ThinkReview daily to:

- Review GitLab merge requests with AI insights
- Analyze Azure DevOps pull requests instantly
- Catch security vulnerabilities early
- Get code quality suggestions powered by frontier models
- Review code in multiple languages
- Save time with zero-setup AI reviews

---

🚀 Why We're Going Open Source

Transparency

We believe developers should know exactly how tools they use work. Open sourcing ThinkReview allows anyone to:

- Verify our security practices
- Understand data handling
- Review code quality
- Audit privacy implementations

Your code reviews deserve transparent tools.

Trust

Open source code builds confidence. When you can see exactly what a tool does, you can trust it more. This is especially important for code review tools that analyze your intellectual property.

Collaboration

The best ideas come from diverse perspectives. By open sourcing ThinkReview, we're inviting developers worldwide to:

- Suggest improvements
- Report bugs
- Contribute features
- Share expertise
- Help make code reviews better for everyone

Innovation

Open source accelerates innovation. When developers can extend and customize tools for their specific needs, everyone benefits from the improvements and learnings shared back to the community.

Education

We want ThinkReview to be a learning resource. The codebase demonstrates:

- Building Manifest V3 Chrome extensions
- Integrating with GitLab and Azure DevOps APIs
- Implementing OAuth authentication
- Creating seamless UI integrations
- Working with AI APIs (frontier models)

---

🛠️ What's Open Source

We're open sourcing the complete browser extension frontend, including:

- ✅ Full extension source code (Manifest V3)
- ✅ UI components and integrations
- ✅ GitLab & Azure DevOps API integrations
- ✅ OAuth authentication flows
- ✅ Complete documentation
- ✅ Contribution guidelines
- ✅ Version history (v1.0.0 - v1.3.8)

What Remains Proprietary

To maintain our competitive advantage and sustainability, our backend infrastructure remains proprietary:

- AI model integration and optimization
- Code review processing pipeline
- User management and subscriptions
- Hosted backend services

The extension requires our backend to function, providing natural protection while allowing complete transparency of the client-side code.

---

📜 Why AGPL-3.0?

We chose the GNU Affero General Public License v3.0 (AGPL-3.0) for specific strategic reasons:

Copyleft Protection

AGPL-3.0 ensures that any modifications to ThinkReview must also be open sourced. This prevents competitors from taking our code and creating proprietary forks.

Network Protection

The "Affero" clause is crucial—if someone hosts ThinkReview as a service, they must make their modifications available. This protects against "SaaS loopholes" in traditional GPL licenses.

Commercial Flexibility

We can still offer commercial licenses for companies that want to fork ThinkReview for internal use with proprietary modifications. This supports our business model while keeping the main project open.

Community Contribution

Contributors can trust that their work will always remain open source and won't be relicensed to proprietary later.
