Cto.new - Build anything with AI, free forever.

What it does

Cto.new is a free, ad-supported platform that lets users build apps, agents, and startups using top AI models from Anthropic, OpenAI, and others. It requires no credit card or API key, and limits reset daily. The platform also includes a marketplace for hiring or listing ready-made AI teams (e.g., engineering, marketing, content).

Who it is for

Cto.new is designed for developers, entrepreneurs, and creators who want to experiment with AI without upfront costs or complex setup. It's also for AI teams looking to offer their services in the marketplace.

Why it matters

By removing financial and technical barriers (no card, no API key), Cto.new lowers the entry point for AI-powered development. The daily reset limits and optional premium upgrade offer flexibility, while the marketplace connects builders with specialized AI teams.

Launch signal

Cto.new launched with $5.7M in seed funding, as announced in a blog post titled "We Raised $5.7M to Launch Cto.new Completely for Free." The platform is currently free and ad-supported.

Brand and naming

The name "Cto.new" suggests a fresh start for building technology (CTO as Chief Technology Officer). The .new domain hints at novelty and creation. The tagline "Build anything with AI. Free forever." positions it as a generous, accessible tool.
