Built for the things AI can’t fake
This tool runs free, right here. The extension adds three things a web widget can’t:
Playground
↗JS / TS scratchpad — sandboxed and instrumented.
Paste real code, hit Run. Console + network monitor + watch expressions all in one panel.
- ·Real ES modules · top-level await
- ·URL imports — esm.sh & friends
- ·Live fetch monitor (every call)
- ·Watch expressions in your scope
- ·10s sandbox timeout · zero CORS pain
HTTP client
↗Postman-style request runner.
Save collections, share variables, hit any API. Includes GraphQL with introspection, OpenAPI / cURL import.
- ·Bearer / Basic / API-key auth
- ·GraphQL · introspection
- ·OpenAPI 3.x · cURL import
- ·Copy as fetch / axios / Python
Realtime (WS + SSE)
↗Stream-protocol tester — what Postman doesn’t do well.
WebSocket + Server-Sent Events with custom auth headers, auto-reconnect, JSON pretty-print.
- ·wss:// + ws:// + subprotocols
- ·SSE via fetch — Authorization works
- ·Auto-reconnect with backoff
- ·Send composer · ⌘ + Enter
What it does
User-Agent strings are how browsers identify themselves. They’re a mess of historical baggage. The parser extracts the actual browser / engine / OS / device / vendor / model from any UA string — including modern AI crawler bots.
