GSTACK // ABOUT US
Mission & Vision
Empowering tournament organizers, broadcast teams, and developers with open, broadcast-grade esports tooling
High-Performance Broadcasting Software
GStack is a specialized organization dedicated to software engineering for esports broadcasting. We create advanced tools to automate broadcasting workflows, acquire factual data through computer vision, and build elite streaming HUDs.
Open-Ecosystem & Developer-First
Built on an open-ecosystem model using standard web technologies (HTML, CSS, JavaScript), our overlays run natively as browser sources in OBS, vMix, Streamlabs, and any streaming software — zero local installation required.
We believe esports production should be accessible, customizable, and developer-friendly. Our APIs are open for anyone to build upon.
