What is Fidelius?

Fidelius stores API keys and other developer secrets in your iCloud Keychain, grouped by project, so every Mac you use has them. In Terminal, accio myproject npm run dev runs a command with that project's keys as environment variables. Key files like .p8 arrive as a temporary path that's deleted afterwards.

Claude Code, Codex and Gemini CLI can be set up to run commands through accio instead of reading .env files. When Claude Code or Codex runs it, key values in the output are masked.

Touch ID guards revealing, copying and exporting a key. There's Recently Deleted, encrypted backups, and no account. Free for one project, $24 once for unlimited projects.
