Cto.new

cto.new is a powerful, completely free AI code agent engineered to eliminate developer friction and context switching. It solves the critical problem of manual task planning and code generation by autonomously planning, writing, and shipping production-ready code across your entire technology stack and workflow. Designed for modern software engineers and engineering teams, cto.new leverages the best frontier LLMs to deliver completed tasks as verifiable pull requests, integrating seamlessly into the tools you already use.

Key Features

cto.new is built around a comprehensive agent system that handles context, execution, and integration, ensuring the AI is a productive member of your team from day one.

🧠 Full-Stack Contextual Planning via Chat

Start a private chat session with cto.new, which maintains context across your entire codebase and connected Multi-Context Providers (MCPs). This capability allows you to discuss tasks, plan complex features, and refine requirements, ensuring the agent generates accurate code and minimizes the need for manual revisions later.

⚙️ Asynchronous Plan and Code Agents

Once a task is defined, cto.new spins up dedicated planning and coding agents to execute the work remotely and asynchronously. These agents operate independently to generate code and documentation, allowing you to close the chat window and continue your high-priority work while the agent autonomously works toward a finished pull request.

🔗 Deep Workflow and API Integrations

Integrate the AI directly into your existing development lifecycle via supported platforms like GitHub, GitLab, Linear, and Jira. You can assign tasks, trigger actions, or start a new task by simply tagging @cto in an issue, adding a specific label, or assigning the issue to the agent, eliminating the need to adopt new project management tools.

💻 Configurable Cloud Task Runners

Tasks are completed inside a dedicated, cloud-based virtual machine called the Task Runner. You maintain control by configuring the environment for each repository, including running setup steps, installing dependencies, and defining code checks (build, test, lint, and format). This ensures that every piece of code generated by the agent is automatically tested and validated against your exact project standards before it is submitted for review.

Use Cases

cto.new integrates into your daily development cycle to manage common, time-consuming tasks, ensuring your team focuses on high-value architectural work.

1. Automated Bug Resolution and Context Gathering: Connect observability tools like Sentry or Cloudflare Observability via MCPs. When a critical bug is identified, you can assign the issue to cto.new. The agent uses the MCP context to understand the production error, plans the fix, writes the necessary code changes, and submits a tested pull request—all without manual intervention on your part.

2. Seamless Feature Implementation from Issue Tracking: Instead of manually translating a Linear or GitHub issue into a series of commits, simply assign the issue to cto.new. The agent reads the issue description, uses its codebase context to plan the steps, creates the necessary files, and executes the coding task, delivering a comprehensive PR that includes the required feature implementation.

3. Expedited Repository Setup and Environment Configuration: When connecting a new repository, the built-in setup agent can automatically configure the Task Runner environment. This capability runs system setup steps, installs dependencies, and defines initial code checks, ensuring the AI can immediately build, run, and test your project correctly, accelerating onboarding for new projects.
