Cosine CLI brings our AI coding agent to your terminal. It writes/refactors/tests code, runs shell, understands your repo, and continues browser tasks. Autonomous or interactive. Full access to familiar local tools. Meeting developers where they work.
I’m Yang, co-founder of Cosine (cosine.sh) along with @alistair_pullen. We’re excited to be back on Product Hunt for our Cosine CLI release!
We originally launched Cosine here in October 2023, and in May 2025, we released our fully autonomous software engineering agent.
💡 What is Cosine CLI?
Cosine CLI brings our agentic software engineer right into your native developer environment: the terminal. Powered by Genie 2, our proprietary model built specifically for complex coding tasks, Cosine is designed to complete tasks end-to-end without human supervision.
Now in the terminal, Cosine is ready to code alongside you in real-time. Cosine CLI is like pairing with a senior engineer who can chat, plan, code, test, and refactor directly inside your projects.
Unique to our CLI is cross-environment integration. Start a task in our browser platform and then pick up the task seamlessly in your terminal. With full access to your local files, run builds, execute tests, and interact with project-specific tools.
📈 Designed for real teams at scale
I’m incredibly proud of our team for this release. It’s exciting to see what developers are able to accomplish with tools like Cosine directly in their native environments.
We’re looking for feedback from devs who maintain large codebases, ship often, pair program, or just those who prefer native workflows.
