FontLab is a font editor developed by Fontlab Ltd., Inc. Since the early 2000s, it has been the dominant software tool for commercial/retail digital font development. This is partly because the once-dominant Fontographer by Altsys ceased development after its acquisition by Macromedia. During Macromedia's merger/acquisition by Adobe Systems in 2005, Macromedia sold Fontographer's rights and code to FontLab Ltd, so FontLab now owns and maintains both of the most popular font editing/development tools. FontLab is available for Windows and macOS.
