cto.new

cto.new is a completely free AI code agent that helps developers plan and ship code using multiple AI models. It works seamlessly with the developer tools you already use, requiring no credit card or API key to get started. The tool is designed to handle various coding tasks, from planning new features to finding and fixing bugs, making it a practical assistant for everyday development work.

What makes cto.new stand out is its ability to leverage multiple AI models (including Claude Sonnet 4.5) and its deep integration with popular developer platforms like GitHub, GitLab, Linear, and Google. Unlike many AI coding tools that focus solely on code generation, cto.new takes a more comprehensive approach by handling the entire workflow from planning to execution. The platform is completely free, which is particularly notable given that it recently secured $5.7 million in seed funding.

This tool is most beneficial for software developers and development teams looking to accelerate their workflow without adding complexity or cost. Real-world use cases include working through development tickets, planning new features, debugging existing code, and managing coding tasks across multiple projects. The seamless integration with existing tools means teams can incorporate cto.new into their current workflows without significant changes to their development process.
