devp1866/github_scrapper — reverse-engineered prompt

Build me a simple web app called GitHub Scrapper where a user can paste a GitHub profile or repository URL and get useful public information back in a clean page.

I want it to feel straightforward, with a small form on the home page, a submit button, and a results page that shows the scraped details in a readable way. Keep the design simple but neat, using normal HTML templates and static CSS. If something goes wrong, like the link is invalid or GitHub does not return anything useful, show a friendly error instead of crashing.

Please set up the Python backend, the scraping logic, the templates, and anything needed so it can run locally and also be deployable on Vercel if possible. Do not overcomplicate it. Just make the project work end to end, with clear file organization and a requirements file. Look up current docs online if you need to.
