A fast, elegant team chat with channels, DMs, voice and video calls, and large file sharing, backed by gap-free message ordering you can actually trust. On web, mobile, and desktop.
Collaboration tools buckle exactly when the team scales.
Most chat platforms are prototypes that got popular. They hold up in a ten-person workspace and fall apart at a thousand: messages arrive out of order, uploads time out, and every new client drifts a little further from the truth.
- Message ordering that quietly breaks under concurrent writes.
- File uploads that fail at exactly the size teams actually share.
- Reconnects that lose whatever arrived while you were offline.
- A UI that feels like a compromise on at least one of your devices.
A collaboration core engineered like infrastructure.
Mesh treats a workspace as a replicated log, not a pile of rows. Every message is sequenced server-side before it fans out, so ordering is a property of the system rather than a hope. The result is a chat that stays elegant and correct on web, mobile, and desktop.
- Server-assigned sequence numbers give total order per channel, always.
- Idempotent sends mean no duplicates, even through a flaky connection.
- Reconnect and Mesh backfills exactly what you missed, nothing more.
- HD voice and video calls with screen sharing, one tap from any channel.
What Mesh does.
Realtime messaging & presence
Persistent WebSocket fan-out with server-assigned ordering. Messages land once, in sequence, on every client, with live presence and typing.
Voice & video calls
Jump from any channel into crystal-clear HD voice or video in one tap, with screen sharing built in.
Share large files
Drag in big files, images, and clips. Uploads stream straight to object storage, so size limits stay generous.
Channels, groups & DMs
Public channels for the whole team, private groups for projects, and one-to-one DMs, organised per workspace.
Reconnect backfill
Drop offline and Mesh replays exactly what you missed. Cold start on a year-old workspace is still instant.
Gap-free & reliable
Monotonic per-channel sequence numbers and idempotent sends mean no duplicates and no lost messages, ever.
How it's put together.
Every layer exists because a guarantee demanded it.
Edge
TLS termination and connection upgrade at the nearest region. Sticky routing keeps a session on one gateway for its lifetime.
EnvoyWebSocketGateway
Stateless Go services holding the socket fan-out. Each gateway owns connections, never state. Losing one costs a reconnect.
GogRPCSequencer
The ordering authority. Assigns a monotonic sequence per channel before anything is durable or visible.
GoRaftStorage
Postgres for the message log and metadata, Redis for presence and cursors, object storage for file content.
