The SPDX group encourages the development of tools that meet the spec and help users and producers of SPDX documents.
Some of these are developed under the auspices of the workgroup, but we encourage others in the the community as well as commercial vendors.
The SPDX group does not endorse (or, at this time, have a certification program for specification compliance) but to encourage the use and product of tooling, we list all the tools here that we are aware of that claim to meet the SPDX spec.
If you have a tool that should be listed, please contact the SPDX Business Team.
For instructions on using the SPDX Workgroup tools below, please read the SPDX Tools Documentation (downloadable from the attachements below).
