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
When you’re prototyping, the difference between Lorem-Ipsum-soup and a UI that looks alive is realistic data. Names, emails, addresses, dates, lorem text — all in one tool.
Two modes: pick a single generator and get N items in one click, or define a JSON shape with {{placeholders}} (like {"id": "{{uuid}}", "email": "{{email}}"}) and get N filled records.
Why use VibeGear's fake data generator
- ✓50+ generators — names, emails, addresses, IPs, dates, lorem, colors, prices
- ✓Args syntax for ranges: {{integer:1:100}}, {{lorem:sentences:5}}
- ✓Type-preserving substitution: "{{integer}}" becomes 42, not "42"
- ✓Output as lines, JSON array, or CSV
