LIVE.TAIL.>

Watch messages as they land

Flip on Realtime and the stream tails itself — every message from a live 3-node cluster, as it arrives. When the firehose is too fast to read, throttle the display rate without touching the stream.

Live tail over any stream or subject filter
Display-rate limit from unlimited down to 1 msg/s
Payloads rendered as JSON, hex or raw — per message

PROTO.DECODE.>

Binary in, readable JSON out

Point Natscope at the Git repo or local directory that holds your .proto files, bind a subject pattern to a message type — and the same payload that was a wall of hex becomes a browsable JSON tree. Everywhere: message browser, live tail, publish preview.

Proto sources from Git, a local directory or pasted files
Subject-pattern mappings with NATS wildcards
Live reload — edit a .proto, watch payloads re-decode

PUBLISH.VALIDATED

Hand-write real Protobuf

Pick a subject pattern and the editor resolves the message type on its own. Type JSON with schema autocompletion and live validation, publish, and watch the message come back — encoded on the wire, decoded on your screen.

Schema-validated editor with field autocompletion
Custom headers, templates and publish history
Plain JSON and text publishing for non-proto subjects

MESSAGES.FILTER.*

Find the message that matters

Filter any stream by subject with NATS wildcards, jump to a sequence, page through millions of messages. Every message opens with its headers, timing and payload views side by side.

Subject filters with * and > wildcards
Headers, hex, raw and decoded tabs per message
Republish or copy any message in one click

CONSUMERS.MANAGE

Consumers, without the CLI

Every consumer with its pending, ack and redelivery counters at a glance. Open one for the full picture — delivery policy, backoff, filters — then edit, pause or resume it right there.

Durable, push and ephemeral consumers
Pause / resume with a visible paused-until badge
Copy any consumer as a ready-to-run nats CLI command

KV.HISTORY

Key-Value with a memory

Browse KV buckets like config trees, edit values with compare-and-set protection, and walk the revision history of any key to see what changed and when.

Buckets, TTLs and replicas at a glance
Stale edits rejected — revision-checked writes
Per-key revision history with diffs

CONNECT.CLUSTER

Zero to connected in a minute

Name it, paste a URL, test, connect. Multiple URLs give you cluster failover; the test shows RTT, server version and JetStream availability before you commit. Credentials go to your OS keychain — never into the database.

Every NATS auth method, full TLS, ws:// and wss://
Saved connections with one-click switching
Secrets in the keychain or an encrypted file vault
