Folia only. TickRadar shows the TPS and MSPT of the region a player is standing in, gives staff a sorted view of every populated region, and alerts your team (in game, in the console and on Discord) when a region starts to lag.

On Folia, there is no single server-wide TPS anymore: every region ticks on its own thread. The usual tools (a global /tps, most tab plugins) either don't run on Folia at all, or quietly average numbers that no longer mean anything. TickRadar shows the number that actually matters: the health of your region.

Features

• Per-player displays: boss bar, action bar and tab footer showing the TPS and MSPT of your own region, each toggleable (/tickradar bossbar|actionbar|tab).
• /tickradar regions: every populated region and the global region, slowest first, with world, approximate coordinates, player count, TPS, MSPT and a one-click [Teleport] link.
• Alerts: configurable MSPT thresholds, with a cooldown so a slow region doesn't spam you, sent to the console, to players holding tickradar.alerts, and to Discord.
• Discord webhook: no bot, no invite. Paste a webhook URL and get alerts in a channel; rate-limit aware and automatically disabled if the webhook is revoked.
• PlaceholderAPI: every value available as a %tickradar_...% placeholder, with a _raw variant for your own formatting.
• Public API only: no reflection into Folia's internals, so TickRadar keeps working across Folia updates.
• English and French out of the box, user-editable and never overwritten.

Main commands

Key permissions

Grant tickradar.display (and tickradar.alerts) to everyone if you want all your players to see their region's health, not just staff.

Performance

Built for Folia's parallel regions, and measured on a real Folia 26.1.2 server:

• About 60 µs per player per second once the server is warm, with boss bar, action bar and tab footer all on: roughly 0.1% of a 50 ms tick.
• No startup hitch: display code is warmed up off the game thread at startup and after every /tickradar reload.
• Player updates are spread across the ticks of each second, so a crowded spawn never gets all its players sampled on the same tick.
• No I/O on game threads: Discord runs on its own thread, and placeholders only read a cache.

Measured on 25/09/2026: Folia 26.1.2 limited to 8 CPU cores and 12 GB of RAM, 3 players each alone in their own region, default settings, average over the last 5 minutes of a 20-minute run. The same test on 4 cores and 8 GB gave the same per-player cost.

Usage statistics (bStats)

TickRadar reports anonymous usage statistics to bStats by default: server and player counts, server and Java version, and a few non-identifying settings. Never player names, IP addresses, world names, coordinates or the Discord webhook URL. Turn it off with metrics: false in config.yml. Public dashboard: https://bstats.org/plugin/bukkit/TickRadar/34279

Compatibility

• Folia 26.1.2 and newer. On any server that is not Folia (Paper, Purpur, Pufferfish…), TickRadar disables itself cleanly with a clear log message.
• Requires Java 25 (Folia 26.x already does).
• Optional: PlaceholderAPI 2.11.7+.
