PlayEDU builds tools people actually run. Education, games, and collector apps are one line of work. Infrastructure and security is the other: Certwatch, hosted Certificate Transparency monitoring for teams.
Each product does one thing: record a game from the sideline, run a factory for a week, decide whether a comic is worth grading, or show which certificates were published for a domain.
Education, games, and collector tools are one line. Infrastructure and security is the other, starting with certificate monitoring.
Open a browser demo for the games. Certwatch is hosted: sign in, add domains, and read the certificates published for them.
Infrastructure and security first. Education, games, and collector pages open on playedu.games.
