HeatProtect
HeatProtect is a Fabric land-protection system whose claims grow out of where players build, instead of forming rigid rectangles.
What it does
Claims are derived from block density. Dense, lived-in areas lock automatically, while scattered blocks stay unclaimed, so land nobody uses is never locked. The claim boundary recalculates as building changes, and a more heavily built area produces a stronger claim with smooth, organic edges. Ownership is read from existing block history, including data recorded by CoreProtect, and the claim territory can be shown live in the world, on Dynmap or BlueMap.
The core system runs on Spigot and enforces protection on block placing and breaking, with checks that are validated instantly. Server owners can tune how aggressively building takes claim land, and trusted players can be added to share a base. An optional companion mod renders the claims directly in the world, and HeatProtect works with Dynmap to show a server-wide territory layer.
HeatProtect is required on the server, while the client may optionally run its companion mod. Files are published for Fabric only, across four release versions, 26.1 – 26.2, under All rights reserved, so the code is not open source. The latest file is for 26.2, released 2026-07-04 on the alpha channel.
Key features
Density-based claims
Claim areas form from manual building density rather than from drawn boxes, so territory follows the real footprint of a base.
Self-maintaining boundaries
Claims recalculate automatically as players build, so server owners do not have to redraw regions by hand.
Tunable aggressiveness
Server owners can configure how much building takes claim land, controlling how strongly builds lock nearby terrain.
Base sharing
Trusted players can be added to a claim and build alongside its owner.
Live map integration
Claim territory can be shown live on Dynmap or BlueMap, plus an optional companion mod that renders claims in the world.

What the author says
An advanced land-protection system where claims aren't boxes you place — they're organic territory that grows from where you actually build. Dense, lived-in areas lock in automatically; scattered junk never claims land nobody uses. Fully automatic, self-adjusting, and visualized live both in-world, on Dynmap, and on…
