Why switch
FontScope vs WhatFont
WhatFont fails on Shopify and other sites with complex CSS layers because it walks computed styles only. FontScope walks both computed and inherited styles, so it surfaces the right font on every modern stack.
| Feature | FontScope | WhatFont |
|---|---|---|
| Monthly price | $2.99/mo | Free (with the trade-offs above) |
| Account required | No — install and use immediately | Often yes (varies by competitor) |
| Data leaves the browser | No — on-device by default | See competitor privacy policy |
| Ownership transfer risk | Aegis never sells extensions | Varies — see ExtensionWatch in this catalog |
| Bundled with Aegis Pro Pack | Yes — $9.99/mo unlocks every extension | No bundle |

Common questions
- Why does WhatFont fail on Shopify?
- Shopify and other modern stacks layer CSS through `@font-face`, design tokens, and component-scoped overrides. Tools that read computed styles only see the override, not the actual font in use. FontScope walks the full stack.
- What does the page audit show?
- Pro audit lists every font family used on the page, the count of distinct weights and styles, and the rendering metrics. Useful for design system reviews and front-end performance audits.
- Does FontScope log the fonts I inspect?
- No. Inspection runs entirely in the page; nothing leaves the browser. There is no usage analytics and no per-site fingerprint.
- How does the Aegis Pro Pack unlock FontScope?
- Sign in to aegisfirma.com from any installed Aegis extension popup. The cookie-auth flow detects your active Pro Pack and unlocks Pro features instantly — no license key to copy or paste.
- Where is my FontScope data stored?
- FontScope stores everything in chrome.storage on your device. Your subscription record lives in our payment provider's account; we do not aggregate browsing or activity data.
- Can I cancel FontScope Pro anytime?
- Yes — billing stops at the end of the current period. Pro features remain active until the period ends, then drop back to the free tier.
- Why should I trust an extension I just heard of?
- Aegis extensions never change ownership and never sell user data. We publish security audit results and ship MV3-native code so Chrome itself enforces the permissions we claim.
