Free Developer Tools

Inspect a live API response without leaving the browser, and get a readable breakdown of any public GitHub profile or repository — activity, languages, and structure at a glance.

Developer tools

Which Developer tool should you use?

The API Response Viewer is for the moment you want to see what an endpoint actually returns without leaving the browser or writing a curl command with the right headers. The two GitHub tools answer different questions: the profile analyzer summarises what a person works on and how consistently, the repository analyzer describes a codebase's size, language mix and activity. Both read public data only.

Developer tools — common questions

Does the API viewer support authenticated requests?
It issues plain unauthenticated requests. For endpoints that need a token, use it to shape the request and confirm the response format, then move the call into your own client where the credential belongs.
Why does the GitHub analyzer show fewer contributions than the profile page?
GitHub's own contribution graph includes private activity for the signed-in owner. Public analysis can only see public events, so the numbers differ for anyone who works in private repositories.
