Secret management without ceremony
Sink keeps application secrets organized by workspace, team, project, and environment. Use the dashboard or API to manage values, then use the CLI to bring them safely into a local.env file.
What you can do
- Sync environment files — pull, compare, and push
.envvalues. - Keep access scoped — organize secrets by workspace, team, project, and environment.
- Import existing variables — migrate from Railway, Vercel, or Render.
- Share securely — create expiring, view-limited secret links.
- Keep history — secret updates create versions.
Start here
- Install and configure the CLI.
- Learn every CLI command.
- Authenticate API requests.
- Manage environments and secrets with the API.
Secret values are deliberately masked by default in CLI output. Use --show-values only when you need to reveal them.
