If your host shuts down when empty (like Aternos or Minehut), you can use a "rejoin bot." Host a simple Python script on a free Oracle Cloud VM that joins your server every 20 minutes. Check your host's rules first; some ban this.

All links tested and working as of this post.

Pro tip: No free host gives perfect 24/7 without some limitation. If you really need 24/7 uptime with zero hassle, consider a cheap paid host like PebbleHost ($2.99/month) – but the ones above are the best free compromises.

This is the only way to get a truly powerful, 24/7 server for free indefinitely. However, it is not beginner-friendly. You are essentially renting a professional cloud computer.

These hosts offer "Freemium" plans. They are often 24/7, but they usually require you to watch ads or log into their website daily to earn "credits" to keep the server running.

Best for: Builders who want a massive world and don't mind restarting the server once a day.

UPD Link Status: ✅ Works with Dynmap

PloudOS is famous in the EU for offering unlimited storage (most free hosts give you 5GB). Your world saves never get deleted.
