ERISCO

About

ERISCO (aka The Eris Corporation) is an independent software company based in Roseville, California, established in 2019. We build online games and the tools that power them, provide infrastructure and cloud engineering consulting, and explore applied AI.

ERISCO is the copyright holder for Hybrasyl and its associated ecosystem of projects.

What we do

Game development

We develop Hybrasyl, an open-source server and toolchain for the classic MMORPG Dark Ages, along with a broad ecosystem of editors, libraries, and developer tools. See our projects for the full picture.

Consulting

We offer consulting in infrastructure engineering, cloud architecture, and platform operations — the unglamorous machinery that keeps software running.

ERISCO AI

ERISCO AI is our applied AI practice: research and experimentation with frontier models, multi-agent systems, and human–AI collaboration.
