NodeCG is a broadcast graphics framework and application that lets you build dynamic, real-time on-air graphics using standard web technologies (Node.js plus HTML/CSS/JS). It provides a server, a control dashboard, and an API for syncing data between dashboard panels and graphics pages rendered as browser sources in tools like OBS Studio, vMix, XSplit, and CasparCG.

Use cases

• create broadcast graphics for livestreams using web tech
• build real-time scoreboards and overlays for esports tournaments
• render dynamic lower-thirds and tickers as OBS browser sources
• control on-air graphics from a web dashboard during a live show
• build charity fundraiser or speedrun marathon broadcast overlays
• replace expensive character generation hardware with free software

When to choose

• you need dynamic, data-driven broadcast graphics rendered via browser sources
• you want full freedom to use any web framework or drawing library for your graphics
• you need a dashboard to control graphics in real time during a broadcast
• you want a free, open-source alternative to commercial CG systems

When to avoid

• you need built-in drawing primitives or templates with no coding
• you need static, non-interactive video overlays that a simple OBS plugin can handle
• your streaming software cannot render modern HTML browser sources
• you want a turnkey graphics solution without writing JavaScript
