## What it is
A web application that generates a shareable image of a user's entire GitHub contribution history, with multiple color themes. It works around GitHub's lack of a statistics API by scraping contribution data and rendering it via a companion canvas-drawing library.

## Use cases
- generate an image of all my GitHub contributions
- create a contribution chart to share on social media
- visualize my GitHub activity since I signed up
- make a themed GitHub contribution graph picture
- self-host a GitHub contributions chart generator

## When to choose
- you want a single image of your full GitHub contribution history for social profiles
- you want multiple color themes for the rendered chart
- you want to self-host the generator on Vercel or locally

## When to avoid
- you need contribution statistics via an official supported API
- you need analytics or metrics beyond the contribution calendar image
- your GitHub profile activity is private, since the tool requires public contributions

## Facets
- artifact type: application
- maturity: active
- function: data-visualization, image-processing, web-scraping
- domain: data-visualization, social-media, developer-tools
- platform: self-hosted
- tags: github-contributions, contribution-graph, canvas-drawing, vercel, themes, nodejs, web-server
