TypeFinder, by designer Anthony Fonte, is a browser-based local typeface viewer that lets you preview the fonts already installed on your computer without installing any software.
Like similar local-font-viewer tools, it reads your system's installed fonts directly in the browser for quick side-by-side comparison.
Fits designers who want a fast way to browse their own installed font library rather than discover new fonts online.
Free to use; tools of this kind typically depend on the Local Font Access API, which only works in Chromium-based browsers (Chrome, Edge), not Safari or Firefox.
