Introduction

Chinstrap Community is proud to introduce Cossmology, a comprehensive, worldwide directory of over 1,000 commercial open source software (COSS) companies.

Submit your company

If you’re working on an OSS project around which you’ve built, or plan to build, a commercial offering, tell us about it by using our Submit feature.

COSS Weekly newsletter

We’ve also launched COSS Weekly, a newsletter that delivers all the latest COSS news, funding rounds, acquisitions, and other headlines to your inbox. No sales pitches, no ads—just the week’s most relevant news from the COSS universe. (check out our COSS Weekly archive)

GitHub dataset

We’ve mirrored much of the Cossmology dataset on GitHub (repository, searchable index) so be sure to star us.
