One developer. An entire engineering team, on Claude Code.
Anja is the engineering system one developer built around Claude Code while shipping a production web app between March and October 2026. It is extracted and cleaned for others to study, use and adapt. Claude Code supplies sub-agents, skills, hooks and memory. Anja adds the discipline between them: who delegates to whom, how sessions share one branch, who reviews what, how a session recovers after a compaction, and how a correction becomes a lesson, a rule, then a guard. Open source, Apache 2.0.
Anja is an open-source engineering system developed around Claude Code, designed to enhance collaboration and discipline among AI sub-agents in software development. It provides structured delegation, session management, and learning mechanisms for developers, and is licensed under Apache 2.0.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
