Hi everyone,
I’m one of the maintainers of user-scanner.
We started building this project around 8 months ago because many classic OSINT tools like became outdated or unmaintained, and there weren’t many solid free options left for email OSINT.
Since then, we’ve been adding sites one by one, continuously improving detection accuracy and maintaining support for platforms that frequently change their APIs and flows.
Today, user-scanner has grown into one of the most actively maintained free Email and Username OSINT tools in 2026. While many web-based alternatives lock basic scans behind paywalls, our goal is to keep powerful email enumeration accessible to the open-source community.
Contributors are always welcome. Adding new sites is relatively straightforward, and even small contributions help a lot.
If you’re interested in OSINT, Python, scraping, automation, or just open-source projects in general, feel free to contribute and help improve the tool.
