What is on this list
Web development, game server hosting and streaming tools, plus the smaller apps that grew out of them. Everything here was written by hand for Windows or the browser, and most of it runs on the same rack in the Netherlands that serves this page.
PlayPort is the game server and website panel for Windows, with Minecraft and Steam servers, backups and mail. StreamKit puts a stream on your own site instead of a platform page. KlantUren keeps hours and invoices, Ondographics draws music, and Brain keeps notes for coding agents. The free tools are listed with their status next to them.
