Minecraft: Java and Bedrock
Minecraft server status
Check a Java or Bedrock server: online or not, players, version, its message in colour and its mods.
Java and Bedrock
Type the address you'd put in the game. A Java address with no port that doesn't answer is tried as Bedrock too.
Its message, as in the game
The server's message in its colours, glitching text and all. Open it in the coloured text tool to change it for your own server.
Players and mods
See some of who's on and open their profiles, and the mod list a modded server shares.
