What is the fastest way to test WebSocket connections without installing anything?

Use DevCrate's browser-based tester: paste URL, pick protocol, send messages—live in seconds, no deps.

Why do WebSocket connections fail in production but work locally?

Mixed content (HTTPS page + ws://), firewall blocks, or missing wss://—tester confirms instantly.

How do I test WebSocket authentication manually?

Connect, send auth JSON first like {"token": "..."}, check pretty-printed response for success or errors.

Why Browser-Based WebSocket Testing Crushes Endless Client-Side Debug Loops

WebSocket failures sneak up fast—connection green, but no data flows. A browser tester flips the script, pinpointing server flaws before you touch client code.
