  • Insomnia installs to %LOCALAPPDATA%\insomnia\ (user-scope). All registry entries are HKCU only.
  • All data (requests, collections, environments) is stored in %APPDATA%\Insomnia\ as a local SQLite database, with optional cloud sync when signed in.
  • The insomnia:// URI scheme supports deep links for opening specific requests or collections.
  • Insomnia is Electron-based and auto-updates without registry changes.
  • Kong acquired Insomnia in 2019; older releases may show Insomnia REST Client as the publisher name.
