Be Inc. hosted OpenTracker until 2001. Before the dissolution of the corporation, both Be developers and outside volunteers contributed to Be's open-source software projects. With Be's dissolution imminent, prominent OpenTracker contributor Axel Dörfler oversaw the relocation of the OpenTracker project to SourceForge, and at the same time began a new software versioning scheme. Dörfler established the new software version at 5.1.0.
Some open-source software developers continued to develop OpenTracker, while others forked the source code into novel variations. One such divergence, Tracker.NewFS, has distinctive source code for file system operations, as well as support for SVG icons. yellowTAB, too, added support for SVG icons in their closed-source fork.
