v1.0.0 — first stable release
Iustitia v1.0.0 — first stable release
A client-sided Fabric anticheat for Minecraft 1.21.11. Watches other players from your client — 32 read-only checks, lag-aware false-positive guards, a cheater-tier prefix on every nametag, and a full observer/moderation toolkit. No server install, no outgoing packets, no telemetry.
What's new in 1.0.0
Observer tooling
- Confidence score & burst pulse — every flagged nametag shows a 0-99 score (e.g.
[X 87]) and briefly pulses when a fresh red-capable alert lands. - Evidence commands —
/ius transcript,/ius evidence,/ius note,/ius session,/ius reportgive you Discord-ready timelines, moderator notes, and full report cards. - Keybind hub — eight configurable binds (snapshot, transcript, session, notes, config, compact, watch, keybinds) with a screen that lists them and highlights conflicts.
- Alert presets, smart batching, audio cues, lag-soften — quiet/normal/verbose severity presets, burst collapsing, note-block cues, and
[lag]-prefixed alerts during server lag. - First-launch wizard — General / Moderation / Ranked presets.
- Optional persistence to
%APPDATA%/.iustitia— notes and tier/flag history survive restarts.
Phase B render overlays (all client-side, no wallhack)
- Target-highlight wireframe, ghost-trail breadcrumbs, burst sparks.
- Watch follow-cam —
/ius spectate [name]or the F9 keybind; mouse-driven orbit, F1 + third-person, auto-exits on movement or being hit. - Nametag-hover tooltip, tab-list tier badges, offender-selfie screenshots.
