About this tool
Parse WebSocket frames from hex in your browser. Pure client-side. WebSocket Frame Parser runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- WebSocket Frame Parser is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
