How to host web apps on a Mac Mini

Recently, I finished migrating my remaining apps — Postcard and Booklet — to the Mac Mini, then shut down my Digital Ocean account. The transition to a home lab is complete. My ongoing costs are $0.33 per month for AWS S3 and email, and $3.56 per month for Mailgun.[1] The home server has served tens of thousands of visitors while using minimal CPU and memory. Testing an app, such as FRCTNL, reveals that it now runs faster. Setting up my home server, which I call “Toolbox,” has been enjoyable. I can build and host personal tools and run them without marginal monthly expenses.
