Start with the surface that matches the moment, not the slogan.

Posted builds can land on different tags. The right choice is whichever surface is actually available and best suited to the session you are starting.

Need the fastest start

Use the browser first. It covers onboarding, invite review, settings, and lighter chat without waiting for a native install.

Start On Web

Need a daily mobile home

Choose Android when a posted build exists. It remains the first-wave native client for day-to-day use.

Check Android

Need a desk-first surface

Choose Windows or Ubuntu when a posted build exists. If neither is posted, treat web as the fallback instead of guessing.

Surface Capabilities

What each surface can actually do.

All surfaces share the same relay contracts and local-first direction, but not every product capability has the same maturity. Current source encrypts conversation attachments before upload across web, mobile, and desktop; production and published-installer parity still require separate verification.

Beyond First Wave

iPhone and macOS remain later-surface work.

They still exist in the repo, but the first-wave release discipline is focused on Android, Windows, Ubuntu, and the browser companion.

Shared relay boundary

Every client uses the same hosted-delivery model, but current history and attachment handling still differ by path.

Shared local-first direction

Keys, search, and DM history stay device-centered. Relay-hosted rooms and legacy groups retain different history and attachment-key boundaries.

Release feed stays authoritative

If a platform build is not posted there, assume web is still the right surface for now.
