There is a free and supported (updated) bedwars plugin called BedWars1058. This plugin has a lot of features, than the abandoned BedwarsRel (BedWarsReloaded) plugin. I would like it to be in the plugins list. That plugin is fully open source, so I can confirm, that it's safe.
Spigot link: https://www.spigotmc.org/resources/bedwars1058-opensource.97320/
There are addons and premade BedWars setup made by the community here: https://wiki.andrei1058.dev/docs/BedWars1058/addons/
There are a lot of new tutorials made for this plugin also, so I definitely recommend adding this plugin.
The only problem may be Bungee support, since I guess the server software is related to Bungee or Bungee it self.
Hope this plugin gets added to the store soon!
The only Goat
This is a really bad idea, talked to the developer personally and he doesn't take care of anything with this plugin. This plugin (not to mention) is one of the worst to get working properly on low RAM servers. I would say stick with BedwarsRel or (not to be annoying) just create your own unique bedwars plugin/script.
Yea it was $20, then someone complained to Spigot that "they originally made it" (yet they did not) and now have full access to the plugin. The premium version was so much better than this free version.
I think this BedWars plugin is quite good compared to BedWarsRel cuz BedWarsRel doesn't even have anyt support and doesn't have as much features as BedWars1058, so I can highly recommend it still
