Works at your desk and out on site.

MQTT 3.1.1 and 5.0

Over TCP, WebSocket or TLS. It gets through HTTP proxies and talks to secured brokers.

Offline first

Lose the connection or restart the app. Your message log is still there.

Every device you carry

iPhone, iPad, Android and Mac, with the same workspace on each.

Dark mode included

Light and dark themes, built in.

Free to start

The free tier already fits a small team.

Questions people ask first.

Any broker that speaks MQTT 3.1.1 or 5.0 over TCP or WebSocket, with or without TLS. You can add your own CA, client certificates and a PKCS#12 bundle.

iPhone, iPad, Android and Mac. Your workspace is the same on every one of them.

Free to start. The free tier covers 4 team members, 3 brokers per workspace and 2 workspaces, and there are no in-app purchases.

Invite them by email and give each person a role: admin, editor or peer. They open the app and the workspace is already there.

Brokers can use TLS with your own certificates, and the app talks to its backend over HTTPS.

Your message log is still there, even after you restart the app.

Your next broker takes ten minutes. Your team's takes none.

Free to start on iPhone, iPad, Android and Mac.
