GitHub User Profiler — Developer Intelligence

GitHub profiles contain rich intelligence about developers: their technical skills, work patterns, organizational affiliations, and contact information. This tool fetches comprehensive data via GitHub's API and reconstructs a detailed persona profile.

Timezone & Schedule Inference

By analyzing the timestamps of public events (commits, issues, PRs), the tool reconstructs an activity heatmap and infers the likely timezone. Weekday vs weekend patterns reveal whether GitHub use is professional or personal.

Technical Profile

Repository languages, topics, and descriptions map the developer's technical expertise and interests. Star counts indicate project impact, while the original-to-fork ratio shows creative vs consumptive behavior.

Events API
GitHub's public events endpoint returns the last 90 days of activity including pushes, PRs, issues, and comments — rich temporal data for behavioral analysis.

🐙 GitHub User Profiler — FAQ

How much API quota does this use?

About 5-10 requests depending on the number of repos. Unauthenticated: 60/hr. Logged into GitHub: 5,000/hr.

Can it find hidden email addresses?

It extracts the public email from the GitHub profile. Commit emails require fetching individual commits which uses more API quota. The tool currently focuses on the profile email and any emails visible in bio/website fields.

Does it work on organization profiles?

It is optimized for user profiles. Organization profiles have a different API structure — org analysis is planned for a future update.

What if the user has no public repos?

The tool will show profile information, organization memberships, and public events (if any). Without repos, language and topic analysis will be empty.

Can I compare two GitHub users?

Not currently built in, but you can export JSON for each user and compare manually. Multi-user comparison is planned.
