Bedrock Edition server software

Description
Unlike PC edition server software, Pocket Edition server software lacks many things that are present in Pocket Edition (e.g. mobs and redstone). Some server software, like Nukkit, has redstone and mobs, but is very incomplete. Likewise in PC edition, Pocket Edition server software is free of Mojang source code. However, servers hosted by a third party have plenty of features, but often have a subscription fee.
