Yes I am back with the same suggestions as my previous thread If you haven't seen it already click here: Add more mcpe server software (Even though it got denied which isn't important). I am here with only 1 server software to suggest. That is NukkitX. I'm here to give you all the information about NukkitX. NukkitX is actually really popular.
Programming Language: Java
Website: https://nukkitx.com/
Plugin API: https://nukkitx.com/resources/
Previous Conversation With Me and Roman and My Reply
Roman: We don't have so much different software just because to have a big variety, it's because every software has it's own pros and cons.
Reply: Pro about NukkitX: It's coded in java increasing performance by alot.
Con about NukkitX: It's coded in java and there isn't alot of people who can code java. That would make you think there are then limited plugins right? Absolutely not! Because of how popular NukkitX is there are 848 plugins!
Roman: To a certain extent, every software also fulfils a certain purpose.
Reply: The purpose NukkitX fulfills is user experience. Performance is better because it's coded in java. NukkitX was originally just Nukkit. Nukkit was made due to the time of PocketMine-MP's inactivity. But when PocketMine-MP started becoming active again they didn't stop and moved to NukkitX. NukkitX has a more active set of developers.
Roman: There is no reason to add multiple different software for mcpe if there is no reason to.
And just to have them to get a big variety is not a good reason.
Reply: I have explained why it should be added.
Roman: If a particular software is useful and offers advantages we can talk about adding it. Any other case doesn't really make sense to me.
Reply: I'll be waiting...
