SpecLens

Desktop reader for tracing how OpenSpec requirements evolved over time

Desktopfreeglobal

SpecLens is a free, open-source desktop reader for OpenSpec projects that shows how specifications and requirements changed over time and lets developers comment directly on specs, working entirely from local folders. It's for teams practicing spec-driven development who need to review requirement history and discuss changes, not just read a spec's current state.
