Aliens Eye: how to use it, and a browser alternative
Aliens Eye is a Python username scanner that tries to cut false positives by scoring each response instead of trusting the HTTP status code. Here is how it works, how to run it, and when a browser checker is the simpler choice.
Username search (CLI). Project: github.com/arxhr007/Aliens_eye · License: MIT · Last reviewed 2026-10-17
What is Aliens Eye?
Aliens Eye is developed by arxhr007 under the MIT license, and the repository was last pushed in October 2026. Its README says it scans 840+ platforms. Each response is turned into a set of signals (status, page structure, keywords) and judged by a heuristic engine and a logistic regression model shipped with the package.
Results come back as Found, Maybe or Not Found with a confidence figure. A Found result is also tested against a username that cannot exist on that site; if the page looks the same, the hit drops to Maybe. The README publishes its own accuracy numbers and tells users to treat Found and Maybe as leads to verify, which is good practice with any tool.
Other options include profile extraction (name, bio, avatar), clustering profiles that look like the same person, following linked usernames, a domain check, watch mode, Tor or proxy routing, an MCP server and reports in formats from JSON and CSV to PDF and graph files.
How to use Aliens Eye
- Install it from PyPI. Optional extras add a browser fallback, PDF output, a terminal UI or the MCP server. A Dockerfile is included too.
- Run aliens_eye followed by one or more usernames.
- Add --site to limit the scan, or --no-nsfw to skip adult sites.
- Use --format all --output results to save every report type, then review each Found and Maybe by hand.
Example commands from the project's README (check it for the current version):
pip install aliens-eye
aliens_eye username
aliens_eye username --site github,reddit,gitlab
aliens_eye username --format all --output resultsAliens Eye vs WhatsMyName Apps

- MIT license, updated in October 2026.

Frequently asked questions

No hosted version is listed in its README; you install it with pip or Docker. For a browser username search, our tool checks 3,165+ sites without setup.
How do I install Aliens Eye?
Run pip install aliens-eye, then aliens_eye followed by a username. Extras such as aliens-eye[pdf] add optional features.
Does Aliens Eye use AI?
It ships a small logistic regression model that it blends with heuristic rules to decide whether a page is a real profile. It runs locally.
Is a Found result from Aliens Eye proof of identity?
No. Its own README calls results leads to verify. A matching handle can belong to an unrelated person, so check photos, links and dates.
