Fontanello review
A free, open-source way to inspect web typography across major browsers and iOS.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Fontanello is a free, open-source browser extension for examining typography rendered on webpages. It is aimed at designers and developers who need quick answers about the typeface and styling behind selected text, including solo practitioners and small teams. A right-click on webpage text opens details about the typeface, font weight, size and color, making the tool suitable for visual reviews, implementation checks and accessibility-oriented inspection.
Its strongest capability is the depth of information shown for a selected text sample. Fontanello reports letter spacing, font variants, font features and variable-font settings, then adds a contrast ratio for the selection. The browser ecosystem is broad: add-ons are available for Chrome, Firefox and Edge, while Fontanello Go brings typography inspection to Safari on iPhone and iPad. That coverage supports teams working across common desktop browsers and Apple mobile devices without changing the basic inspection workflow.
There is no paid tier to compare because Fontanello uses a free model, and its open-source approach suits lightweight evaluation without licensing costs. Support channels are email and community, which fits an independently oriented tool more than a managed enterprise service. Choose Fontanello when the job is identifying and evaluating typography directly on live webpages. Choose another category of tool when you need to inspect standalone font files, manage a font library, or perform broader design-asset administration; Fontanello stays focused on rendered webpage text.
