Every face has a name.

The stylesheet calls it “brand-serif”. The file is Gloock.

Both are free, need no account and ask for no site access. Fontsight also reads the font file, flags faked bold, finds free look-alikes and lets you try them on the page.

Checked October 24th, 2026 from both store listings and packages, and tested side by side.

At a glance.

What each one does, and what it asks of you.

Same page, three hard cases.

One test page where the CSS and what’s drawn disagree. We pointed both at the same text and wrote down what each said.

  1. 01 · A renamed font

    font-family: "brand-serif", Georgia, serif; /* the file is Gloock */

    Drawn in Gloock

    Fontsight said
    Gloock, read from the file, “as brand-serif”
    WhatFont said
    brand-serif, “Web font”

  2. 02 · A font that never loads

    font-family: "Proxima Nova", "Helvetica Neue", Arial, sans-serif;

    Drawn in Helvetica Neue

    Fontsight said
    Helvetica Neue, installed here, not loaded by the page
    WhatFont said
    Helvetica Neue, “Installed font”

  3. 03 · A faked bold

    font: 800 34px Inter; /* only Inter 400 is loaded */

    Drawn in Inter 400, thickened to look like 800

    Fontsight said
    Inter 800, flagged: faux bold, only 400 is loaded
    WhatFont said
    Inter, weight 800, no warning

Where WhatFont is good.

WhatFont is fast, free and well made. If all you need is a font’s name and its CSS, it does the job.

  • It asks for as little as Fontsight does: no install warning, no account.
  • It names the face that rendered from the font stack, and got our fallback test right.
  • It says where a font comes from: Google Fonts, Adobe Fonts, a web font or one installed on your computer.
  • It works in Safari on Mac, iPhone and iPad.
  • Three million people use it, and it was updated in October 2026.

Questions, answered.

Is Fontsight a good WhatFont alternative?

Yes, if you want more than a name. Both are free, need no account and show no install warning. Fontsight also reads the font file to name fonts a site has renamed, flags faked bold and italic, finds free look-alikes, lets you try fonts on the page and lists every font in a side panel.

Can WhatFont identify a renamed font?

Not in our test. On a page where the stylesheet calls Gloock “brand-serif”, WhatFont showed “brand-serif”. Fontsight read the file and named Gloock.

Is WhatFont free?

Yes. Its listing and website say it’s free, and it has no account or paywall.

Can I use both?

Yes. Neither runs until you click it, so they don’t get in each other’s way.
