✨ Design Your Card Visually

While we offer a robust API, you don't need to touch a line of code to get the perfect look. Our Interactive Visual Builder lets you customize your fingerprint in real-time:

• Real-time Preview: See changes instantly as you toggle themes and layouts.
• 10+ Designer Themes: From the deep tones of Obsidian to the vibrant Sakura.
• 5 Distinct Layouts: Choose a Terminal look for dev tools or a Banner for project headers.
• One-Click Copy: Once you've perfected your design, grab the Markdown or HTML snippet and drop it straight into your README.

🚀 How it works

Stack Fingerprint deep-scans any public GitHub repository via the Contents API — reading lockfiles, config files, and directory structures — to detect the frameworks, runtimes, and tooling in use.

• 70+ detection signals — languages, frameworks, bundlers, test runners, CI, linters, infra.
• Real brand icons — inlined as base64 at render time, fully CSP-safe.
• Zero Configuration — No tokens, no environment variables, no friction.

Help us grow the Fingerprint Database

Is your favorite framework missing? Adding a new detection signal is as easy as adding a JSON object to src/data/signals.js:

{
  id: "astro",
  label: "Astro",
  category: "framework",
  iconSlug: "astro",
  color: "#FF5D01",
  match: {
    files: ["astro.config.mjs", "astro.config.js"],
  },
}
