Cosine has always been deeply integrated with GitHub, pulling in your existing repositories and working alongside your established workflows.

But there’s been a missing piece. What if you want to build something new fast? What if you’re just getting started, or testing an idea that doesn’t yet live in an existing repository?

Start from fresh on Cosine

You can now create blank projects directly on Cosine with no external setup required.

Just click “New Project” and start from a blank canvas. Our fully autonomous software engineer brings your ideas to life.

This shift makes Cosine more accessible to everyone, from first-time coders and domain experts to hackathon builders and product engineers. If you’ve ever hesitated because of GitHub overhead, we’ve made it so you can handle everything on Cosine.

Everything on platform

Behind the scenes, we’ve added native code hosting powered by a high-performance, self-hosted Git service. When you start a blank project, Cosine creates a private Git repository in our infrastructure. You get the full power of source control (commits, branches, diffs) with none of the friction.

It all happens on Cosine:

• Edit and manage files

• Track history and changes

• Collaborate with your team

• Build, test, and ship code

And of course, you’re still able to bring in your existing repositories. 

Integrated GitHub support

If you already use GitHub, nothing changes. You can still import your repositories, link them to Cosine, and keep your GitHub workflows intact. In fact, our new system enhances GitHub support behind the scenes by mirroring repos internally, enabling faster AI operations and eliminating GitHub rate limits.

You choose the workflow. Cosine adapts.

Import from URL live for everyone

In June, we introduced the ability to import repositories from any Git-based repository via URL, allowing users to access repositories from platforms such as GitLab and Bitbucket.

This was previously only available to select customers upon request. Now, it’s available for everyone.

We’re ensuring that developers truly own their workflows while using Cosine.

Built for the future of AI engineering

This isn’t just about convenience. Hosting code on Cosine unlocks new capabilities:

• Real-time AI editing and previews

• Integrated CI/CD, deployment, and testing workflows

• Smarter context tracking and intermediate code states

• Faster AI iteration – no more waiting on external APIs

By owning the end-to-end development experience, Cosine asserts itself as a platform – not just a tool – for building software in the AI era.

Start building instantly

If you’re already using Cosine, click “New Project” and see how fast you can get from zero to running code.

New to Cosine? Now is the best time to try. You can spin up a project, write code, and collaborate with AI on your ideas in seconds.
