AI systems you can build, test and use.
Openroot is a practical newsletter for builders working with agents, automation, infrastructure and AI-powered 3D.
Agents and automation
Understand working agent systems, useful tools and workflows, including the decisions and failure modes behind them.
Infrastructure and operations
Practical context for running software: reliability, deployment, security, cost and the tradeoffs that matter after a demo.
AI-powered 3D
Explore where AI tools meet real 3D workflows, with hands-on experiments and implementation lessons.
Open-source building
Useful discoveries and project breakdowns, connected to a developer community focused on software people actually use.
Written by Kristofer Jussmann. Subscription and the publication archive are hosted on Beehiiv at the existing readbitstream address. Builder applications are separate and do not subscribe anyone to the newsletter.
