Cosine CLI - AI pair programming directly in your terminal
by•
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.

Hey Product Hunt! 👋
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.

I'll be in the thread all day answering questions!

There were two main things we wanted to achieve when we started work on the CLI: bring our best-in-class coding agent to people’s local devices and to give them a level of flexibility that they’ve never seen before in a CLI.
Unlike other agentic CLI products out there the Cosine CLI allows you to sync your tasks with the cloud platform, meaning if you start a task in the CLI, it can be synced to the cloud, and then you can pick up right where you left off from any other device. This works in the opposite direction too.
The workflow this enables relative to other local only one-task-at-a-time CLI products actually enables the core promise of agents: massively parallelised workflows which is something that hasn’t been easily done locally - until now.
Give the CLI a try today - the first 80 tasks are on us!
@alistair_pullen the free tier is very generous thanks you!

Whoa, running an AI coding agent straight from the terminal is wild—no more jumping between tools! I waste so much time context-switching, so this is honestly a game-changer for my workflow.

We feel you @cruise_chen. Since rolling out the intiial builds of the CLI internally, we've peaked our all time code output.
Theres so many features and bugs that we've been able to add in meer days where, a year ago It would have easily taken weeks.
@yang_cosine 1 month PRO! That's a generous offer!
Do you have user-guide/docs for it? I could see a Blog section though.
Wanted to see if Cosine CLI can help me with handling the code of static site generators.

@yang_cosine @ashok_nayak
It most certainly can!
you can get started with just a Cosine account and the install command on https://cosine.sh/cli

@yang_cosine Great! I will check it shortly. Thank you!

Our CLI release is a massive achievement for the team. Really looking forward to seeing how it transforms workflows. Being able to start tasks in our browser platform and pick them up seamlessly in the terminal is a game-changer.
Let us know how you find using it!
This is huge - having such a powerful agent directly in my existing workflow has been game changing. It doesn't get in the way as I'm writing code, I can just hand it tasks and when I'm ready to accept changes they come through into my workspace, I'm loving it.
Using the CLI tool in my editor's terminal has greatly boosted my output! I'm working on getting new features across a large monorepo, so I'll work on one service or the front end while getting the AI to build up the corresponding other end of the flows I'm working on. Super awesome stuff!
I did a vibe test, gave Cosine this simple prompt:
The generated landing page is well structured, doesn't feel "AI" at all, and the copy is quite impressive!
This is a really good launch.

@tonkinai This is really cool, glad you're enjoying it!
very cool, can stay in the terminal now 🔒
