I built a tool that turns any GitHub repo URL into a shareable social card (free, no login)

Every time I want to share a GitHub project, I run into the same problem: a raw GitHub URL looks bad on social media, screenshotting the repo page is messy, and making a proper card in Figma takes time I don't have.

So I built RepoCard — paste any public GitHub repo URL and get a clean, shareable social card back instantly.

Try it: https://repocard-delta.vercel.app


What it does

Paste a repo URL like https://github.com/vercel/next.js and it generates a card with:

  • Repository name and owner avatar
  • Description
  • Primary language with color indicator
  • Star count
  • A subtle "made with RepoCard" stamp

You can download it as a PNG or use it directly.


How it works (under the hood)

  • 100% client-side — no backend, no server
  • GitHub public API for all repo data (no auth needed for public repos)
  • html2canvas for PNG export
  • Deployed on Vercel free tier

Zero running costs. The whole thing is a single-page app.


The business model (being honest about it)

Free tier generates a card with a light watermark in the corner. $7 one-time removes it and unlocks two premium templates.

I'm trying to get the first paying customer this week. Haven't spent a dollar on marketing — starting with genuine communities first.


Day 1 numbers

Just launched. Watching for first 100 visitors. Will share the actual numbers in a follow-up post as they come in.


What I'd love feedback on

  1. Does the card look good enough to actually share? (Be brutal.)
  2. What repo would you want to generate a card for?
  3. Is $7 the right price, or is free-only the only viable model here?

The tool is live — paste your own repo in and tell me what breaks or looks wrong.
