I'm Sam — a software developer with 30+ years of experience. SaaS subscriptions keep climbing, and most of the tools we rely on daily could be built better, cheaper, and with more respect for your data. So that's what I'm doing. This site is home to the free utilities and self-hosted apps I've built to replace the things I was paying for — secure file storage, webmail, a music library, media streaming, and more. Everything here is built by me, for real use.
