kosa8 cloud
Run sandboxes on kosa8 Cloud (api.kosa8.com)
kosa8 Cloud runs the same sealed sandboxes on kosa8's hosts, or on your own, billed by the second. Sign in once (kosa8 login, or an API key), then make, run in, sleep and remove cloud sandboxes from here; the dashboard at https://app.kosa8.com shows the same ones.
kosa8 login # sign in in your browser kosa8 cloud login --key k8c_live_… # or with an API key (CI) kosa8 cloud sandbox create # prints its ID and a dashboard link kosa8 cloud sandbox exec ID -- uname -a kosa8 cloud usage # this month's bill so far kosa8 cloud mcp # connect Claude Code, Cursor or Codex
The key is kept in ~/.kosa8/cloud.json, readable only by you, and shared with the kosa8 desktop app. KOSA8_API_KEY and KOSA8_API_URL, which the SDKs read, take precedence when set.
