CeeGee

Self-hosted broadcast graphics for everyone

An open source HTML titling engine with a real-time web control surface. Build, control, and display broadcast-quality overlays from any browser.

Why CeeGee?

A lightweight alternative to commercial broadcast graphics systems, designed for small and medium productions.

Runs entirely on your own hardware. No cloud dependency, no subscription, no vendor lock-in.

WebSocket-driven operator UI lets you take, clear, and edit graphics live with instant feedback.

Drop an overlay URL into an OBS Browser Source and you're on air. Works with any tool that renders HTML.

Ships with lower thirds, bugs, billboards, clocks, and countdowns. Build your own with Vue and GSAP.

Separate views for building show structure and controlling live output, so each role gets exactly the UI they need.

MIT licensed. Read the code, extend it, contribute back. No black boxes.

CeeGee follows a simple three-step workflow.

Use the Producer UI to create workspaces, channels, layers, and elements from built-in or custom graphic modules.

The Operator UI provides a live control surface to take and clear graphics on air, with real-time WebSocket sync.

Point any HTML-capable renderer — OBS Browser Source, a second monitor, or a web browser — at the overlay URL.

Everything you need to run CeeGee or build on top of it.

Installation, show setup, the operator interface, OBS integration, and the built-in modules reference.
