UIMessage exists for one reason: private conversations should feel effortless and stay yours. So we built the whole thing ourselves — and we sweat every detail.
Built in-house, on purpose.
When you control the whole system, you control the trade-offs — and we choose privacy and quality every time.
Owned, not rented
The message router, media pipeline, call signaling, group-call server, relay and encryption are our own code, so we control their security and performance trade-offs.
Encrypted end to end
Messages, calls, photos and statuses are locked on your device with keys only the devices in the conversation hold. Our servers pass them on and forget each message once it’s delivered.
Calm, native, fast
Thoughtful, native apps that respect your time — no clutter, no dark patterns, no ads.
Free for everyone
We build a messenger we're proud of, not a product that monetizes your attention.
