Extract JS WebSocket URLs
Extract WebSocket constructor URL strings from pasted JavaScript without opening sockets, executing code, fetching endpoints, bundling, or uploading source.
0 / 30,000 characters. No upload, storage, or account required.
JS WebSocket URL extraction workflows
Use this extractor when pasted browser source needs a local inventory of realtime connection endpoints before API, security, migration, or release QA review.
Audit realtime endpoints
Pair WebSocket URLs with Extract JS Fetch URLs, Extract JS Storage Keys, and Extract JS Error Messages.
Review browser behavior
Use Extract JS Event Listeners, Extract JS Timer Calls, and JavaScript Formatter.
Clean copied output
Send extracted endpoints to Remove Duplicate Lines, Sort Lines, or Normalize Whitespace.
Quick answer
Extract JS WebSocket URLs is a browser-based extract JS WebSocket URLs for checking copied developer data such as payloads, URLs, encoded values, identifiers, snippets, or logs without sending the input to a server.

- Runs on copied snippets in your browser; no account or saved input.
- Workflow
- Developer Data Toolkit
What this tool does
Extract JS WebSocket URLs scans pasted JavaScript as text, lists literal new WebSocket URL arguments, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract WebSocket constructor URL strings from pasted JavaScript, TypeScript, client source, tests, or copied browser snippets before realtime API audits, migration notes, security reviews, or release handoffs.
Use Extract JS WebSocket URLs when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste JavaScript, TypeScript, browser snippets, client source, tests, or copied code that may create WebSocket connections.
- Choose whether duplicate rows should be removed and whether extracted URL text should be normalized for comparison.
- Review WebSocket endpoints with source-line context, then copy the list for realtime API audits, migration tickets, security review, or release handoffs.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
This extractor runs locally in your browser. Your pasted code is not uploaded, executed, rendered, fetched, bundled, stored, logged, or used to open WebSocket connections.
