cto.new

cto.new is an enterprise-grade autonomous AI software engineer developed by Engine Labs, built to solve developers' subscription fatigue. It is more than a chat assistant: it is a full-fledged AI development team that executes tasks directly in your workflow. Through an innovative freemium model, developers can call frontier top-tier large models for free without attaching a credit card.

Core Capabilities

• Autonomous end-to-end workflow: Handles the full pipeline from reading Jira/Linear tickets and planning requirements to writing code, running tests, and automatically submitting Pull Requests.
• Marketplace of ready-made AI teams: Offers a preset agent marketplace covering roles from frontend development and SRE operations to marketing, delivering plug-and-play virtual teams.
• Isolated cloud sandboxes: Assigns each agent a remote dedicated virtual machine (Task Runner) that completes isolated builds and thorough self-testing before code is submitted, keeping your local environment clean.
• Deep ecosystem integration: Natively supports the MCP protocol and connects seamlessly to enterprise development and collaboration platforms such as GitHub, GitLab, Slack, Sentry, and Notion.
• Aggregation of frontier models: With no complex API key configuration, it natively supports the latest top-tier large language models such as GPT-5, Claude 4.5, and Gemini 2.5 Pro.

Use Cases A great fit for independent developers on a budget, full-stack startup teams, and technical teams that collaborate asynchronously through GitHub pull requests and ticketing systems, efficiently clearing backlogged bugs or scaffolding tasks.

Unique Advantages Unlike Cursor, which focuses on high-frequency interactive local coding, cto.new specializes in asynchronous, fully handled service away from your local environment. Its data-for-free model breaks AI coding's high subscription barrier and enters the value market with outstanding cost performance, making it a true asynchronous AI teammate that can independently complete work.

Editor's Review cto.new's product philosophy of weaving AI seamlessly into modern ticketing and PR workflows is highly advanced, and its zero-cost access to frontier large models is extremely attractive for independent developers. Although the free tier's data privacy policy may give enterprises handling sensitive code pause, for teams that want to automate tedious tasks it is an indispensable, best-in-class productivity choice.
