Open GTM Index
A transparent guide to open-source go-to-market software.
What it is
Open GTM Index ranks open-source alternatives to common sales, marketing, analytics and support tools, with a documented scoring method and public project facts behind each result.
A TanStack Start site presents category leaders, sortable rankings, licence details and the score weights used, all backed by public project metadata and a checked-in source workbook.
