GitHub Contribution Chart Generator

Overview

The GitHub Contribution Chart Generator renders your GitHub contribution graph as an SVG image (or PNG) you can drop anywhere — READMEs, blogs, websites. Keyless and free (verified live: the /api/v1/{username} SVG endpoint works).

Quick Start

Contribution chart SVG (verified live — octocat):

curl "https://github-contributions.vercel.app/api/v1/octocat"

Embed in a README:

![Contributions](https://github-contributions.vercel.app/api/v1/octocat)

Options (light/dark, PNG output):

![Contributions](https://github-contributions.vercel.app/api/v1/octocat?format=png)

Authentication

None — keyless.

Rate Limits & Notes

• Free; no documented hard limit — be polite (it hits the GitHub API server-side).
• The chart mirrors the GitHub contribution calendar (yearly grid).
• ?format=png returns a PNG instead of SVG; dark/light variants available via params.
• It’s a convenient alternative to GitHub ReadMe Stats’ contribution section (whose hosted instance is currently paused as of 2026-08).

FAQ

Is it free? Yes — free and keyless.

How do I embed it? Use the image URL directly in a README or <img> tag.

Does it show the current year? It renders the contribution calendar like your GitHub profile page.
