Aternos is arguably the most famous free host. It is designed for ease of use.

: Known for its 99.9% uptime guarantee, ScalaCube’s free plan uses the same high-end infrastructure as its paid versions. It allows your friends to join at any time without you needing to manually "wake up" the server.

Some users sign up for free VPS trials (like Google Cloud or AWS Free Tier) and install the Pterodactyl Panel.
