Cyv
by morpheye
With Cyv, players can read parkour jump data on screen, including coordinates, angles and personal bests with high decimal precision, in a client-side Fabric or Forge mod.
What it does
Cyv ports the parkour features of CyvClient for 1.8.9 to Fabric and Forge, and a Forge build exists for 1.8.9 and 1.12.2. The mod changes how the client tracks movement: an offset tracking system records repeated attempts at the same jump, and tick-based keystrokes support clip analysis and sharing. Quality-of-life options such as toggle sprint and a direction HUD sit alongside these tools.
Most features are reached through the base command mpk, which opens the options that control the on-screen labels. Because it only runs on the client, the mod does not need to be installed on a server, and players on any server can use it while it stays local. Files cover 1.8.9 – 26.3 across 22 release versions, with 1.6.1+26.3 as the latest Fabric file and Forge-1.10.1 for 1.8.9 as the latest Forge file.
The mod is published under All rights reserved, so it is not open source, though its source code is public. Cyv was first published on 2024-03-11 and last updated on 2026-10-14.
Key features
On-screen jump labels
Labels show coordinates and angles at each jump, with high decimal precision for measuring personal bests.
Attempt offset tracking
Repeated attempts at the same jump are tracked with an offset system, so differences between runs can be compared.
Tick-based keystroke data
Keystrokes are recorded per game tick, which supports clip analysis and sharing of recorded input.
Quality-of-life toggles
Toggle sprint and a direction HUD are included among the options reached through the mpk command.
