F3 Nope

F3Nope is a lightweight Fabric mod that lets you completely customize — or remove — the Minecraft debug overlay.

• Hide Vanilla Debug Info – Strip away all default F3 information
• Custom Text Display – Show your own text instead of debug data
• Fully Configurable – Toggle features and edit text via commands or config
• Placeholder System - Add Variable that autofill time, date, version and more
• Live Editing – Change settings in-game without restarting

You can configure everything with a config file or by using in-game commands, below are a few examples.

/f3nope text add hello world
/f3nope text add "MC %mc_version% | FPS: %fps%"
/f3nope toggle hideVanillaDebug true
/f3nope position 100 100
/f3nope color 0a36b2
