OSS – AI bot that fixes code via GitHub mobile app

FixO Dev Bot is revolutionizing how developers handle code quality and maintenance. Instead of spending hours on repetitive fixes, linting, and formatting, simply mention @fixodev in any GitHub issue or PR, and watch as our AI-powered bot delivers professional-grade improvements directly as pull requests.

To eliminate the friction between identifying code issues and implementing solutions, making high-quality code accessible to every developer and project.

We believe that:

• 🔧 Code quality shouldn't be a luxury - Every project deserves clean, maintainable code
• ⚡ Automation beats manual work - Developers should focus on creativity, not repetitive tasks
• 🤝 AI should augment, not replace - Intelligent assistance that learns from your codebase
• 🌍 Open source drives innovation - Community-driven development creates better tools
