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

YAML is the canonical config format for Kubernetes, GitHub Actions, Docker Compose, OpenAPI, and a thousand other tools. JSON is what most APIs and code actually consume. The converter bridges the gap.

Backed by js-yaml, so anchors (&foo / *foo), multi-document streams, and the full YAML 1.2 spec all parse correctly.

Why use VibeGear's yaml to json

✓Full YAML 1.2 — anchors, references, types
✓Proper handling of multi-line strings (| and >)
✓Local-only
