Cosine

Surfaces

A surface is where you interact with Cosine. Cosine can be used from Cloud, CLI, Desktop, and VS Code, but these are not separate products. They are different entry points into the same agentic software engineering system.

For help choosing which surface to start with, see Ways to use Cosine.

The four surfaces

Section titled “The four surfaces”
  • Cloud — A browser-based workspace for running tasks remotely, managing projects, reviewing changes, and coordinating work with your team
  • CLI — A terminal-first interface for local development, debugging, command execution, and tool-heavy workflows
  • Desktop — A native app that combines a visual workspace with access to local files and local workflows
  • VS Code — An editor surface for working with Cosine alongside open files, selections, and code context

Many teams use more than one surface. For example, you might connect repositories and review work in Cloud, use the CLI for local implementation, and use VS Code when you want Cosine inside your editor.

Surfaces vs environments

Section titled “Surfaces vs environments”

Surfaces and environments answer different questions:

  • Surface — Where you control Cosine from
  • Environment — Where Cosine runs code, commands, tools, and tests

For example, you can interact with Cosine from Cloud while the work runs in a remote environment. You can also interact from the CLI while Cosine works directly in a local repository on your machine.
