Developer Browser is a focused web viewer designed for inspection and troubleshooting.
Load any URL (or search from the address bar) and review what the page returns and what it does at runtime.
Features:.
Response headers at a glance. Capture the latest HTTP status, MIME type, and full header list.
Console stream. View console output plus JavaScript errors and unhandled promise rejections with timestamps.
DOM snapshot + search. Capture a structured DOM tree with tag, id/class hints, text preview, and a searchable path.
Page source. Read and copy the rendered document HTML in a monospaced view.
Audit deck. Quick structural and accessibility signals (headings, buttons, landmarks, language, unlabeled links, missing alt/labels) plus basic timing info.
Cookies for the current host. See cookie name, value preview, domain/path, secure/session flags, and expiration.
Session timeline. Keep a running list of captured responses as you browse.
Use it for debugging, QA checks, and lightweight page reviews without leaving your browsing context.
