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
