I found a free Minecraft server hosting tool that gives 8GB of RAM.
The first step looks a bit harder than other hosts but it sounds like it is worth it if you stick with it.

GG.MINEWIND.NET New Server IPHosting That Actually Cares
I found a hosting service made by a Minecraft server owner who got tired of lag and scams. They say they have been making servers for 11 years so they know the pain.
They focus on good support and stable servers. They also talk about tools to help with installing plugins or mods. The whole vibe is that customer service matters the most.
They say if your server gets stuck or you get lag they will help you fast. They also share that they now run a lot of machines and have a lot of customers so it feels like a real operation not some random ad.
