Say it like no one is listening.
Ekko is a privacy platform: one private identity for every app you already use. Messages seal themselves on-device with hybrid post-quantum encryption (X25519 + ML-KEM-768) and travel through the apps you and the people you talk to already have open. No new messenger, and nobody to talk into switching.
Status: public alpha. The code is here. It works, we use it daily, and it has rough edges — that's what building in public looks like. Install it, read every line of it, break it, and tell us.
Install Ekko v0.8.0 from the Chrome Web Store →
TestFlight for the iOS app is next.
| Surface | What it does | Status |
|---|---|---|
| Browser extension | Seals and opens messages in the page, inside Instagram, WhatsApp Web, Telegram Web and Messenger. | Public alpha — install v0.8.0 from the Chrome Web Store, or build from a release |
| Directory | Maps @handles to public keys so people can find each other. Optional: skip it and trade invites by hand, or self-host it. | Open source (AGPL), running |
| iOS app | Your identity on the phone: recovery phrase, contacts, safety numbers, your @handle. | Code public, TestFlight next |
| iOS keyboard | Ekko's own keyboard, so encryption reaches inside the native messenger apps, not only the web ones. | Code public, TestFlight next |
| Safari extension | The same protection in Safari, on iPhone and on Mac. | Code public |
One identity spans all of it. The same recovery phrase produces the same keys in the browser and on the phone, so a message sealed in Chrome opens on iOS, and the reverse.
- Open source. The extension (ekko-core), the iOS app (ekko-ios), the protocol, and the directory server. GPL/AGPL — it stays open.
- Self-hosting. Run your own directory. No dependency on us.
- Free core, forever. Encrypting your own messages will never be a paid feature.
- No telemetry. We count downloads and newsletter signups, not you.
- ekko-core — the extension, the protocol, the directory server.
- ekko-ios — the iOS app, the keyboard, the Safari extension.
