Matrix is an open standard for interoperable, decentralized, real-time communication. It allows you
to chat across different providers (like email) without being locked into a single platform.
Matrix Activity Tracker crawls the Matrix federation to
discover public rooms and measure their real-time message activity.
📊 Activity Calculation
Every room is periodically scanned by reading recent messages and calculating a messages per
hour rate. This is smoothed over time to filter out spikes. Rooms are ranked primarily
by this activity rate, with member count as a tie-breaker.
🔍 Room Discovery
The system automatically crawls known Matrix servers every 5 minutes, viewing their
public room directories respectfully. New servers are discovered from room metadata.
➕ Missing a Room or Server?
Use the Add field in the header to manually add anything the crawler hasn't found
yet. You can enter:
#room-name:server.org — a room alias
!roomid:server.org — a room ID
server.org — a server domain (scrapes all its public rooms)
A matrix.to link — auto-detected and resolved
Batch Add
Paste up to 100 rooms, aliases, or servers — one per line.
