What WebSocket Tester does
WebSocket problems are easier to isolate when connection state, close codes, incoming frames, and outgoing messages are visible in one timeline. The browser connects directly to the target endpoint; ParseNest never proxies the traffic.
Common uses
- Test a development WebSocket endpoint
- Inspect JSON messages and close codes
- Reproduce authentication and subprotocol problems
Privacy and limitations
The browser connects directly to the address you enter. ParseNest does not receive the URL, headers, or messages. Browser security rules still apply.
Validate important output in the actual language, database, or target platform.
Frequently asked questions
Can I add arbitrary headers?
Browser WebSocket APIs do not allow arbitrary request headers. Use a query parameter, cookie, or a server-supported subprotocol where appropriate.
Why does ws:// fail on an HTTPS page?
Browsers block insecure mixed content. Use wss:// when ParseNest is opened over HTTPS.
Does ParseNest proxy or store messages?
No. The connection is created by your browser and the event log stays in the current tab.
