Tinkerfont is a free Chrome Extension and Firefox Add on that lets you inspect, replace, and test fonts on live websites without opening DevTools or editing stylesheets. It scans the DOM to list all fonts in use, allows you to swap them with over 1,900 fonts from Bunny Fonts or your own uploaded files, and scopes changes to specific page elements. Rules persist per hostname, and you can share setups with teammates via a link or JSON export.
