NATS Explorer v0.1.15
Browse NATS JetStream streams and subjects from VS Code, and inspect messages with a beautiful JSON viewer. Inspired by Qaze.
Features
What you get
Connection manager
Add, edit and delete NATS connections — user/password, token or TLS. Color-code and tag them; credentials stay in VS Code Secret Storage.
Tree browser
Connection → Streams → Subjects, right in the sidebar where it belongs.
Latest-N message table
See the newest messages of a stream or subject, newest-first, without touching a terminal.
Detail sidebar
Inspect message headers and syntax-highlighted JSON payloads in a detail panel built for reading.
Subject filter
Narrow a stream view by contains or regex, with case-sensitive variants when you need precision.
Stream & subject info
Read-only config and state for streams, plus message counts for subjects — a health check at a glance.
Pro upgrade
NATS Explorer Pro
The extension is free for everyone — personal and company use, no business license needed. Pro is optional: it lifts the saved-connection cap from 5 to unlimited. Everything else stays free either way. Works offline after activation.
