STEa keeps planning, delivery, testing, and documentation in sync. Harls is a Miro-style board for discovery, Filo a Trello-meets-Jira board for builds, Hans turns acceptance criteria into test cases, and Ruby keeps living docs in one place. Everything links — move work seamlessly through each stage. Add AutoProduct to turn a brief or a prompt from within an LLM into a complete, testable backlog of Epics, Features and Cards (stories).
