In simple English
This tool finds email addresses on any web page you visit. It checks if the email is real and works. All your data stays on your computer. You do not need to pay for a subscription or create an account. It replaces paid tools that track your searches.
What it is
Trawl is a privacy-first browser extension built with TypeScript. It scans web pages for hidden or obfuscated email addresses, tests their mail servers, and lets you export the results.
What it is good for
Solo founders and researchers who want to gather contact leads from company websites without paying for expensive online services.
- Runs entirely in your browser with zero cloud storage or telemetry.
- Extracts emails from hidden tags, obfuscated text, and JSON-LD blocks.
- Exports clean lists to CSV, JSON, and vCard formats.
- Requires manual loading of the built folder if you install it from source instead of the store.
- Relies on public DNS servers for MX record checks which can be blocked by some networks.
- Only works inside Chromium-based web browsers.
