Security & Compliance

Built for Developers

Everything you need to ship real-time experiences, without the infrastructure overhead.

PLATFORM

One platform. Every real-time primitive. Chat, activity feeds, video, audio, and moderation on shared infrastructure. Stop duct-taping point tools together.

SCALE

Built for millions, by default. High concurrency and global message volume out of the box. Reliability is the default, not a config flag.

SHIP FASTER

Ship in weeks, not quarters. Real-time infra takes years to build in-house. Skip it and get back to shipping your actual product.

DEVEX

SDKs you'll actually enjoy. 10+ SDKs, typed APIs, clear docs. Drop it in today — usually under 50 lines to first message.

PRODUCTION READY

SOC 2 on day one. Battle-tested at scale and maintained by 50+ engineers across every SDK. No rewrite when you grow up.

FLEXIBLE

Your UI, your stack, your rules. Customizable components and open APIs fit any design system or architecture. Zero lock-in.
