Streamer.bot // overlay-er.cs
Overlay(er)
Overlay(er) is a Streamer.bot C# tool for building one browser-source composition from multiple web overlays or local files. It includes a WPF control window, live position preview, autosave, compositor server control, and lifecycle cleanup.
CurrentRequires CRNTLY UIv2.2.1WPFWinFormsStreamer.botC#
Setup
- Create an action in Streamer.bot.
- Add a Core > C# > Execute C# Code sub-action.
- Add every editor reference listed on this page.
- Copy the source below into the editor and choose Save and Compile.

What it does
One OBS sourceLayer multiple web overlays or local HTML files into one browser-source composition instead of managing a stack of OBS sources.
Live layout controlMove and size overlays from the control window with smooth live preview, then persist the finished layout automatically.
Streamer.bot lifecycleThe tool owns its local compositor server, saved state, auto-start behavior, and cleanup inside the Streamer.bot action lifecycle.
