What Horizoverlay is

Horizoverlay is a horizontal damage-meter overlay for Final Fantasy XIV that shows player DPS, damage percentage, HPS, maximum hit, encounter duration, and total DPS. It is intended for players who use ACT overlays to view combat metrics. Setup requires the hibiyasleep OverlayPlugin with ACT, at version 0.3.3.13 or higher; users load the Horizoverlay URL in the plugin’s overlay field. The maker suggests setting the overlay width to about 70% of the screen. Settings save automatically, and the project describes the overlay as highly configurable. It supports English, Portuguese, Simplified Chinese, Traditional Chinese, and French. Users can also build and serve it locally, then direct ACT to http://localhost:5000. The software is free, and the repository lists an Apache-2.0 license. The project accepts suggestions, bug reports, and questions through GitHub issues, and links optional donations to the maker’s Patreon page.
