Free Server Tools

Server Ping Tester. Reach for this when players say hits feel delayed but your console looks clean. The probe runs from a Southeast Asia measurement point, so the number is close to what a SEA player sees, not what a tester in North America would report. Read it in bands: under 30 ms is excellent and fine for PvP, 30 to 60 ms is good for survival, 60 to 100 ms is playable with a small delay on block placement, and above 100 ms you get rubber-banding.

Config Generator. Use it after your player count changes, after you add or remove plugins, or when a major Minecraft version lands. It prints server.properties settings, and on Paper, Spigot or Purpur it also prints paper-global.yml and paper-world-defaults.yml settings. Everything comes out as one block, so split it at the marker comments and paste each part into the matching file. Pick Fabric or Vanilla and you get server.properties plus a short note instead of the Paper YAML.

TPS Calculator. Run this before you pay for a bigger plan. It estimates ticks per second from your CPU, RAM, plugin count, player count and server software. A tick rate of 20 is perfect, 18 to 20 is healthy, 15 to 18 shows up as mild lag in mob movement, and below 15 gets frustrating. The related number is MSPT, milliseconds per tick, where each tick has a 50 ms budget. Past roughly 4 to 6 GB, extra RAM does nothing for tick rate: single-thread CPU speed drives it.

MOTD Generator. This is the cosmetic one, for the two-line message players read in their server list. It writes the color and formatting codes for you and previews the result live. Keep each line to roughly 45 to 60 visible characters or the list will cut it off. Hex colors need Paper or Spigot 1.16 and newer.

Server Status Checker. Use it to confirm from the outside that your server is reachable and to read back the player count, version and MOTD it broadcasts. It speaks the Java Edition Server List Ping protocol over TCP, port 25565 by default, so a dedicated Bedrock server will not answer it, though a crossplay server running Geyser still replies on its Java port. Offline while the server is running usually means the firewall or the port. Connection refused means the address is reachable but nothing is listening there, so the process crashed or has not finished starting.
