Teams and coding agents lose crucial context between meetings, specifications, implementation, testing and release; agents also waste time rediscovering stable browser behavior.
st4ck · Product lifecycle workspace for humans and AI agents
st4ck connects stakeholder input, requirements, decisions, code context, engineering work and regression testing in one structured workspace. Product owners, developers, QA and AI agents work from the same evolving context instead of rebuilding it in every tool and conversation.

Teams and coding agents lose crucial context between meetings, specifications, implementation, testing and release; agents also waste time rediscovering stable browser behavior.
An alpha product that combines stakeholder material with existing code to create structured product documentation, manages requirements and engineering work, and turns browser flows into repeatable pre- and post-change regression tests.
st4ck also supports Bumblebee delivery: shared product context, agent collaboration, structured specifications, browser flows and verification remain connected throughout the work.
