FontFootprint

A weekly audit that scans your live site and tells you which fonts are slowing you down, costing you licensing fees, or breaking under GDPR.

Target user

Marketing leads and site owners at small businesses who didn't build the site themselves and aren't sure what fonts are actually loaded

Features
  • Automatic scan of every font request your site makes, broken down by WOFF1 vs WOFF2 vs system fonts
  • Cost and licensing summary listing each foundry and any commercial-use concerns
  • Performance impact estimate with concrete suggestions to merge weights or switch format
  • Weekly email digest with a single 'fix this' CTA per font issue
Why now

With WOFF2 now standard and accounting for the majority of font requests, the legacy fonts and weight bloat on small business sites is the obvious next thing to clean up.

Signals · overall 5/10
Demand
4/10

Free font-audit tools already serve a fragmented user base (FontTest, FontUsed, AbackTools, uFonts, InspectWP, Web Aloha); the source trend (13-pt HN thread on WOFF 1.0) is weak social signal and the WOFF2-is-standard premise actually argues against widespread legacy bloat.Font performance audit — FontTest · FontTest

Whitespace
3/10

Direct competitors already do exactly this audit: FontTest reports payload/render-blocking/font-display/unused weights/Core Web Vitals; InspectWP adds GDPR check; AbackTools, uFonts and Web Aloha all offer free URL-based font scanners — market is crowded, not wide-open.Font performance audit — FontTest · FontTestGoogle Fonts & Webfont Checker - GDPR check for fonts | InspectWPWeb Font Loading Analyzer - Font Performance Audit Free | Aback ToolsWebsite Font Scanner (Free) | Find Fonts Used On Any Site - uFonts

Monetization
4/10

Most competing font scanners are free with generous limits (FontTest: 5 free audits/day, no account); Font Checker Pro offers tiered plans but the niche is commoditised, and small-biz marketing leads rarely budget for a single-purpose scanner — willingness-to-pay evidence is thin.Font performance audit — FontTest · FontTestPricing — Font Checker Pro Plans for Individuals, Teams & Enterprise

Longevity
7/10

GDPR pressure is real and growing — multiple EU court rulings against googleapis.com transfers, and self-hosting Google Fonts is now a recurring compliance recommendation — so the compliance angle has multi-year tail; font-bloat/CLCP impact also persists as long as third-party fonts ship.Is Google Fonts GDPR Compliant in 2026?

Feasibility
7/10

Trivial to prototype — load URL in a headless browser, log font network requests, parse CSS for font-face declarations, cross-reference with font-display/Core Web Vitals APIs; competitors clearly built similar tools with small teams.Font performance audit — FontTest · FontTest
