Custom Overlay — OBS streamer themes

Twitch streamer overlay system with 9 themes, Rust-backed fetch, locked dragging, OBS browser-source compatible.

Result: 9 themes

RustTauriJavaScriptOBSTwitch API

Live overlay system for OBS browser source — 9 themes, lockable widgets via startDragging(), fetch routed through Rust backend to bypass CSP issues with Twitch API.

Highlights

Rust fetch backend — Tauri command bypasses browser-source CSP, can hit Twitch / YouTube / chat APIs
Lockable widgets — startDragging() toggle prevents accidental moves during live stream
9 themes — full re-skinning per theme, no CSS-merge collisions

What you get

Custom overlay for any vertical — esports HUD, gaming streams, music streams. Tauri pattern is reusable for any “browser-source plugin needs native escape hatch” requirement.
