cto.new is an AI-driven development platform that acts like an intelligent coding teammate, helping developers and teams plan, generate, test, and ship production-ready code with minimal setup. The tool uses cutting-edge large language models — including GPT-series, Claude, and others — and integrates deeply with existing workflows and tools like GitHub, GitLab, Jira, Linear, and Slack. Developers can start a chat session to discuss tasks or issues and spin up dedicated agents that plan work, write and refactor code, run tests, and open pull requests ready for review.

One of cto.new’s biggest selling points is accessibility — it offers completely free access to these powerful AI capabilities without requiring an API key or credit card, lowering barriers for students, solo builders, and small teams. The platform maintains context across an entire codebase and connected tools so the AI can intelligently handle complex engineering tasks, accelerate feature development, and streamline repetitive coding work.
