The same autonomous engineer across desktop, cloud, and terminal.

Start in the Cosine app

A richer workspace for active engineering: multi-window workflows, visible agent state, reviewable changes, and a clean bridge into cloud execution.

Collaborate in the cloud

Run work in parallel, keep long-running tasks moving, and give engineers, PMs, and stakeholders one shared place to plan, review, and ship.

Keep going in the terminal

Stay in a terminal-native workflow with local-to-remote execution, MCP tool access, project context, and multi-agent orchestration from the command line.

Unlock value at every stage of the SDLC
