Minecraft TPS & Lag Monitor
Paste your /tps, /mspt, timings or spark output and find out exactly what is slowing your server down, with plain-language fixes ranked by impact.
Input
Paste your server output
A bare /tps line is enough. Colour codes and console timestamps can stay in the paste — they are stripped for you.
Nothing leaves your browser. Everything is parsed locally.
Ctrl + Enter also runs the analysis.
What TPS means
Reading the number
- 20 TPS the server finishes every tick with time to spare. Perfect.
- 19.5 to 20 fine. Normal wobble, nobody feels it.
- 15 to 19.5 noticeable. Mobs stutter, hits feel late, redstone drifts.
- Below 15 severe. The world visibly runs in slow motion.
MSPT is the other half of the story: one tick has a 50 ms budget. Above 50 ms the server cannot finish a tick in time and TPS starts falling.

How to get the numbers
Commands worth running before you paste
/tps every Spigot, Paper and Purpur server. Gives the 1m/5m/15m averages. This alone is enough for a useful reading.
/mspt Paper and forks. Milliseconds per tick, which shows a problem earlier than TPS does.
/spark health or /spark profiler, paste the text output. Not the link: this tool never fetches a report URL.
/timings report paste the text you can copy out of the report. The percentage column is what gets ranked.
