Get the Sparse desktop client
Sparse is a local desktop app. It sits next to your editor, talks to your model provider with your key, and never uploads your source code.
Local-first by design
Your code and keys never leave the box
BYOK, stored locally
Your Anthropic, OpenAI or OpenRouter key lives in your OS keychain. Model traffic goes straight from your machine to the provider — never through our backend.
Source code never uploaded
Prompts, file contents, diffs and terminal logs stay on disk. We can't read them and we don't want to.
Aggregate usage only
What syncs to your account: token counts, model name, run mode and estimated cost. No paths, no content. That's what powers your dashboard.
