Browser OSINT tool and web username scanner

Run open-source intelligence investigations directly in your web browser with zero CLI setup. Sweep usernames across 500+ platforms, check email breaches, and audit DNS security from any device.

Open browser OSINT scanner

No Python, Git, or browser extensions required. Works in any modern desktop or mobile browser. Ethical public-source research only.

Why use a browser-based OSINT platform?

Most open-source username scanners were designed as terminal utilities that require Python runtimes, command-line flags, and manual JSON maintenance. When you need to check a handle or verify a breach quickly on a laptop, tablet, or phone, setting up a local CLI environment slows you down.

MyRecon delivers a complete reconnaissance console in the browser while preserving rigorous evidence standards:

Instant zero-install execution: Open the web console and run username, email, password, IP, or domain checks immediately without installing packages or browser add-ons.
Client-side k-anonymity privacy: Password exposure checks hash your input locally in the browser via the Web Crypto API and transmit only a 5-character SHA-1 prefix.
Cross-device workspace: Switch seamlessly between desktop browsers, mobile browsers, and the MyRecon Android app.

What you can investigate in the MyRecon browser console

Public username enumeration: Check handles across 500+ social, developer, creator, and forum platforms with reverse username lookup.
Deep Search web correlation: Surface public posts, profile references, and cross-platform links with Deep Search.
Email breach and exposure review: Audit whether an email address appears in public breach records and review historical breach analyses.
Domain, WHOIS, and mail security: Inspect RDAP registration data, SPF, DKIM, and DMARC policies, and IP geolocation from the browser.
Search operator generation: Build targeted Google, GitHub, and Reddit queries using the interactive OSINT cheat sheet.

Frequently asked questions about browser OSINT tools

What is a browser OSINT tool?

A browser OSINT tool is a web-based open-source intelligence platform that runs directly in your browser on desktop or mobile without requiring command-line scripts, Python packages, or local software installation.

Can I run a full 500+ platform username scan in my web browser?

Yes. MyRecon executes multi-platform username sweeps, email breach checks, password k-anonymity lookups, and domain DNS/WHOIS queries directly from any modern web browser.

How does a browser OSINT scanner protect my password during leak checks?

MyRecon uses client-side SHA-1 hashing and k-anonymity in your browser. Only the first 5 characters of the SHA-1 hash are sent to the API, and the returned suffix list is compared locally in your browser so your full password never leaves your device.

How does MyRecon compare to browser extensions or CLI tools?

Browser extensions require broad site permissions and can fingerprint your browsing activity, while CLI tools like Sherlock require terminal setup. MyRecon works in a standard browser tab with zero permissions or installation, and also offers a dedicated Android app.

Does the browser OSINT scanner work on mobile phones and tablets?

Yes. The MyRecon web console is fully responsive on iOS, Android, macOS, Windows, and Linux browsers, and Android users can also use the native MyRecon Android app.

Privacy and responsible browser reconnaissance

MyRecon queries only public endpoints and never installs background tracking extensions. Use the browser scanner for your own accounts and authorized security research in accordance with our terms of use and privacy policy.
