gstack

gstack is Garry Tan's (YC CEO) Claude Code workflow as a public repo. It ships 23 specialized agents that act like a virtual engineering team, plus slash commands like /office-hours, /review, and /ship that drive end-to-end product work from one terminal.

The agents play roles: CEO, designer, engineer manager, QA lead, and more. The idea is that a solo dev orchestrates the team through commands instead of doing every job in series. TypeScript core with some Go for the parts that need speed. Everything lives in .claude/, nothing touches your PATH, and a persistent Chromium browser daemon handles visual testing and QA loops. MIT licensed.

Solo devs and tiny teams are the target. If you're already shipping by yourself with Claude Code, this is a real upgrade. Bigger teams will trip over the opinionated roles, since you already have a real designer and QA lead and don't need an agent pretending to be one.

The catch: this is one founder's workflow turned into a kit. If your style doesn't match Garry's, you'll fight the agents instead of using them. It's also Claude Code only. No Cursor, no Codex, no swap-in for other harnesses.
