Detailed Introduction
cto.new provides a browser-first, free AI code agent that helps users generate code snippets, diagnose issues, and offer implementation suggestions. The service integrates frontier models such as Anthropic and OpenAI to power its capabilities, and it requires no credit card or API keys to start. The product focuses on natural-language driven coding tasks and lowers the friction for engineers to experiment and prototype.
Main Features
- Completely free: no credit card or API key required to use the service.
- Multi-model access: leverage different models for broader capability and comparative results.
- Browser-ready: no client installation needed — interact with the agent directly in the web UI.
- Code-focused UX: optimized flows for generation, completion, explanation and debugging tasks.
Use Cases
cto.new is useful for rapid prototyping, generating example code, preliminary code review assistance, and exploratory Q&A for engineering problems. CTOs and engineers can use it to validate implementation ideas, produce sample code, or help triage common issues to improve development efficiency.
Technical Features
- Multi-model routing and result comparison to balance accuracy and cost.
- No exposure of user API keys: simplifies onboarding and reduces configuration effort.
- Built with modern front-end stack (Next.js / Vercel) for responsive interface and scalable backend connections.
- Emphasis on pragmatic, low-friction experience for day-to-day developer assistance.
