GoKawiilNo serious EU cloud provider gives away permanent free compute. What you get instead is very cheap compute.
Hetzner Cloud's CX33 server configuration is the sweet spot at around €7 a month for 4 vCPUs, 8 GB of RAM, and 80 GB of disk. That is enough to run a Django or Rails app with a Postgres database, Redis for caching, background workers - with plenty of headroom. If your idea finds traction, you scale up vertically for a long time before you have to think harder about it. For your average boring CRUD-style app, this server configuration could even be considered overkill.
Netcup is the runner-up with similarly cheap VPS plans starting under €5 a month. Slightly less polished console, but the price-performance is excellent and they have been around since 2003.
