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.

I'll be in the thread all day answering questions!
Interesting! I'm gonna have to check it out. Would you say that the main differentiator is the ability to switch from CLI to browser? Are you planning also to have a VSCode extension or some other tighter IDE integration?
Best of luck to the whole team!
Congrats on the successful launch of Cosine!
A game-changer for anyone working with complex codebases. Wishing you massive adoption ahead!
I did a vibe test, gave Cosine this simple prompt:
Create a landing page for a telegram bot that help create reminding using natural language
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.
I do like terminal coding and AI in it is a good thought.
The IDEs give a lot more functionality than just writing code, will those also be provided? Building from scratch vs debugging legacy code, the indexing, the highlighting etc. I hope you understand my point.
I see more infrastructure engineers use this, may be wrong, all the best.
Big win for dev productivity 👏 Most of us live in the terminal anyway, so this feels very natural. How fast is the cross-environment switch?
The fact that it integrates into the workflow rather than requiring adaptation is what I find to be particularly helpful. Connecting to the flow that developers currently use on a regular basis—such as repos, PR systems, and terminals—makes adoption much simpler. This appears to be intended to minimize context switching and keep things in familiar locations, but occasionally AI technologies cause more problems than they solve.
This is interesting because it goes beyond just code suggestions. Most tools stop at autocomplete or small snippets, but this is tackling end-to-end tasks. The ability to understand the repo, make changes, and even open PRs makes it feel more like an actual teammate than just a tool. I can see this helping smaller teams ship faster without needing to scale headcount right away.
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!
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.
@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.
No way, AI pair programming right in the terminal is exactly what I’ve been missing—juggling between browser tools and the CLI is such a flow killer. Super curious how it handles complex repo structures!
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.
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!
I want to ask resolution to 2 queries:
1). As a sole user for free plan, i can ask approx 80 queries a month form AI coding agent while building one project (May a person allowed to use application to build project or it gets initiated from other two plans only) ?
2). Seat refers to giving the login access to multiple users for editing purposes?
