Owned, not rented
The Go message router, media pipeline, signaling, SFU, and TURN relay are built in-house, so we control their security and performance trade-offs.
Messaging we're proud to own.
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.
Documented trust boundary
The iPhone client encrypts personal content before relay. The server identity directory remains trusted, and Signal-style verification and ratcheting are not implemented yet.
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.
Straight from the newsroom.
Product news, security deep-dives, and stories from the team building UIMessage.
