uOS: one private workspace in the browser — chat, mail, meetings, files, docs, calendar + 20 apps under one identity. End-to-end encrypted, post-quantum, Swiss-hosted. The server only ever holds ciphertext. Free for individuals, alpha by invitation → uos.sh
UltimaOS — Your private, post-quantum encrypted workspace

UltimaOS — Your private, post-quantum encrypted workspace

Chat, mail, notes, files, documents and more — together in one friendly workspace that opens in your browser. Locked so well that not even we can read your things.

Your workspace provider can read your messages, files and documents. uOS can't, by design. A private workspace that runs like a desktop in one browser tab. 25 apps, one identity. Everything encrypted on your device before it leaves, post-quantum. uos.sh/register

Two friends of mine, both engineers, have been quietly building this for years: A private workspace that looks and feels like a whole operating system, 25 apps, inside a browser tab. Everything encrypted on your device, so the provider literally can’t read you. Post-quantum. (built by @PatFromuOS & @ultimaos_real)
