Best For Professions:
gstack is an open-source workflow and tool collection for coding-agent planning, review, browser QA and release work.
Named planning, review, QA and release workflows cover a coherent software-delivery process.
Installation and a compatible coding-agent host are required, alongside repository-specific setup.
MIT workflow source is free; the agent host, model usage and execution infrastructure are separate.
Use it with a compatible agent host and a repository whose tests and deployment process you control. It adds workflow structure rather than replacing the underlying model or agent.
