Here's a tiny PAAS that can be used if Caddy is too complex.

Sailor is a tiny PaaS to install on your servers/VPS that uses git push to deploy micro-apps, micro-services, sites with SSL, on your own servers or VPS.

Sailor looks really cool! Just took a peak at the codebase and it already seems very interesting compared to other self hosting PaaS solutions.
