Latest release

On first install Android asks you to allow Install unknown apps once — it's a one-time grant for sideloaded releases. From there, the app auto-updates itself through this same manifest.

Hermes on desktop

Theseus bundles Hermes as an always-on sidebar panel — one keyboard shortcut, same recovery phrase, same inbox as every other device. Hermes.exe is the standalone Tauri window for anyone who already has their own browser and just wants Hermes in a tab.

Theseus Navigator

BUNDLEDHermes ships with Theseus — no separate install.

Hermes.exe (standalone)

Native desktop window, same web messenger inside.

Hermes on the web

Hermes also runs here, in this very browser, right now — no download at all. Same recovery phrase as the native apps.
