A new GitHub repository tracks which open source operating systems comply with age verification laws in Brazil and California, with proposed legislation in Colorado, Illinois, New York, and Michigan. The resource documents how distributions like Omarchy Linux, Devuan, and Slackware have chosen not to implement verification systems.

Several distributions including Ubuntu, Pop!_OS, and elementary OS have announced plans to eventually implement age verification, though none have fully complied with legal requirements yet. Midnight BSD has temporarily forbidden usage in Brazil and California until implementation is complete.

As of the latest update, no open source operating systems have fully implemented the required age verification systems for Brazil or California. This creates a compliance gap that affects users in these jurisdictions, potentially restricting access to certain distributions while developers navigate conflicting philosophies of open access versus legal requirements.
