OSINT Browser Toolkit (2026): Capture, Archive, Analyze

This is a starter stack for ethical, legal, public-source research—not a map of the entire OSINT universe. It is optimized for browser-first workflows: find, preserve, enrich, report.

1. Capture and archive: PageStash

PageStash (browser extension + workspace) is your “save it now” layer: full page, screenshot, HTML/text where possible, full-text search, folders, Page Graphs for relationships.

Use it when delay means loss—breaking news, volatile pricing, policy edits.

2. Historical lens: Wayback Machine

The Internet Archive helps answer “what did this URL look like before?” It is not complete or private, but it is essential context. Pair PageStash (your copy) with Wayback (public history) when both apply.

3. Domain basics: WHOIS and DNS

WHOIS (where available) and DNS records support attribution and infrastructure questions. Treat data as noisy, redacted, and jurisdiction-dependent.

4. Identity breadcrumbs: username search

Cross-platform username reuse is a common pivot. Use reputable search tools and document queries like any other source—with notes and captures.

5. Media pivots: reverse image search

For photos and graphics, reverse image tools help find earlier appearances and context. Capture result pages that matter—SERPs change.

Hygiene

• Scope and authorization: only what you are allowed to research.
• Separate personal and case browsers if policy requires.
• Log your reasoning in clip notes—future you is also an investigator.
