This is amazing! im running a minecraft 1.21.1 server with scalacube below the recommended plan, yet it still works perfectly. it has a wide variety of offerings built-in and thousands of modpacks! if you ever get stuck with something, they have lots of tutorials on youtube to help you! overall best hosting experience ive had in a long time.
