WebLogs: Local-first API tester & event logger
Your data never leaves your machine. WebLogs runs entirely in your browser — nothing uploaded, no account, no servers, no tracking. (An extension that shows you tracking, while doing none of its own.) Captured data lasts only for your session and clears when you close the tab.

=======================================================
See what any website is really doing.
=======================================================

Every page quietly fires API calls, analytics events, and tracking beacons. Normally that's invisible unless you open DevTools and dig. WebLogs shows it all live, in a clean side panel.

1. Live capture — requests stream in the moment they fire as you click around.
2. Full payloads — complete request & response bodies, JSON pretty-printed and readable.
3. Analytics X-ray — instantly see what's sent to Amplitude, Mixpanel, Segment, GA4 and more.
4. Replay & test — grab any request, tweak the URL, headers, or body, and re-fire it using the page's own cookies and auth.
5. Smart filtering — search URLs and payloads, filter by method, static files hidden by default.

Built for developers debugging APIs, PMs and analysts checking events fire correctly, QA testing endpoints, and anyone curious what a site sends and to whom.
Zero config. Open the panel and go.
