Getting help with NATS Explorer
Frequently Asked Questions
I can't connect to my NATS server.
Check the server URL and port (default 4222). Make sure your Mac can reach the host and that the authentication method matches the server: user and password, token, NKey, JWT, a credentials file, or TLS. For a quick test, start the embedded server in the app and connect to nats://127.0.0.1:4222.
The embedded server won't start.
Port 4222 may already be in use by another nats-server on your Mac. Stop the other server or choose a different port in the app, then start again.
How do I subscribe and publish?
Connect, then add a subject to subscribe to. Wildcards * (one token) and > (the rest) are supported, and queue groups are optional. In the Publish panel enter a subject and payload, add headers if needed, and send. Use Request to send a message and wait for one reply.
Which features need Pro?
Pro is a one-time in-app purchase. It adds JetStream management (create, purge and delete streams, fetch messages, manage consumers), the KV and object store browsers, the server monitor, protobuf decoding and CSV export. Restore a previous purchase from the About dialog.
The app crashes or freezes.
Make sure you're running macOS 13 (Ventura) or later. If it happens again, contact support with your macOS version, the app version, and what you were doing when it happened.
