Made with open-source software.

Playstack exists because maintainers share the languages, frameworks, tools, and infrastructure that make ambitious software possible.

This is a representative list of the projects used directly by the site and package suite, not a complete inventory of transitive dependencies. Each project remains the work and trademark of its respective maintainers.
