A quick walkthrough from account creation to your first agent run.
Sign up on this site with your work email. This account lets the desktop client sync usage metadata and manage your devices.
Grab the installer for macOS, Windows or Linux from your downloads page. Sparse runs entirely on your machine.
Launch Sparse and sign in with the same email you used above. The client registers your device automatically.
Paste your Anthropic or OpenRouter API key into Sparse's settings. Keys are stored on your machine — never uploaded to our servers.
Point Sparse at any local git repo. Sparse builds a lightweight repo map so it can pick the minimum context for each task.
Choose Cheap, Balanced, Deep or Full Context. Sparse fits context to the job — you always know what's being sent.
Only token counts, model, mode, cost estimate and timestamps are synced back to your account.
