Three major products from Altsys for PC / Macintosh and NeXT were:
- Fontographer for Windows and Mac OS - font editor
- Font-O-Matic for Windows - font transformer
- Virtuoso for NeXT / OpenSTEP and Solaris - vector editor (a version was announced, advertised and demonstrated for Windows NT, but never released)
Altsys' best known product that was basically rebranded Virtuoso, that was licensed to Aldus Corporation under the FreeHand name, was a vector drawing program that competed with Adobe Illustrator. It was published for many years, originally only on the Macintosh, then also for Microsoft Windows. When Aldus was acquired by Adobe, the licensing agreement that Altsys had with Aldus precluded FreeHand from being part of the deal, so the publishing rights reverted to Altsys. Altsys also published Metamorphosis for Macintosh, a font utility.
