ghstats

Generate SVG cards summarizing a GitHub user's profile — written in Go.

ghstats is a single-binary CLI (and a GitHub Action wrapping it) that fetches public data for a GitHub user and writes a themed set of SVGs you can embed in your profile README:

• Profile details
• Repos per language (how many owned repos use each language as primary)
• Most commit language (last year's commits attributed to each repo's primary language)
• Stats (stars, commits, PRs, issues, PR reviews, contributed-to)
• Productive time heatmap (weekday × hour)

Use as a GitHub Action (recommended)

Drop this in .github/workflows/ghstats.yml in your profile repo (the one named after your username):

name: ghstats

on:
  schedule:
    - cron: "0 0 * * *" # daily
  workflow_dispatch:

permissions:
  contents: write

jobs:
  cards:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v5
      - uses: tiennm99/ghstats@v1
        with:
          user: ${{ github.repository_owner }}
          token: ${{ secrets.GHSTATS_TOKEN }}   # classic PAT with read:user + repo
          themes: dracula,github_dark,tokyonight
          tz: Asia/Saigon
          commit_changes: "true"

Then embed the cards in your README.md:

![profile](./output/dracula/0-profile-details.svg)
![repos-per-language](./output/dracula/1-repos-per-language.svg)
![most-commit-language](./output/dracula/2-most-commit-language.svg)
![stats](./output/dracula/3-stats.svg)
![productive-time](./output/dracula/4-productive-time.svg)

-commits-per-repo	100	Max commits sampled per repo
-list-themes		Print available theme ids and exit

Themes

Run ghstats -list-themes for the full list (60+ themes ported from github-profile-summary-cards). Built-ins include default, dark, dracula, github, github_dark, tokyonight, onedark, nord_dark, nord_bright, gruvbox, radical, synthwave, monokai, solarized, solarized_dark, transparent, and more.

Output

output/
  dracula/
    0-profile-details.svg
    1-repos-per-language.svg
    2-most-commit-language.svg
    3-stats.svg
    4-productive-time.svg

Tokens & permissions

The default ${{ github.token }} can read public user data but will not see your private-repo commits. For accurate stats, create a classic personal access token with read:user and repo, save it as a repo secret (e.g. GHSTATS_TOKEN), and pass it via the token input.
