How it works
From sign-in to your first spec visualization in under a minute.
Sign in with OAuth. SpecStat only requests read access — no write permissions ever.
Pick any repository you have access to. Private repos are fully supported.
SpecStat finds openspec/index.json and parses all referenced spec files in real time.
Switch between 6 views — Stories, Graph, Tree, Timeline, Proposals or Archive.
6 ways to explore your specs
Every visualization mode is purpose-built for a different part of how engineering teams use specs.
Read specs as structured stories with full detail, status, contributors and linked resources.
Track proposed changes and design decisions before they become spec.
Navigate your spec index in a collapsible folder hierarchy — just like your repo.
See spec relationships as an interactive node graph. Zoom, pan, click to explore.
View how specs evolved over time — who changed what and when.
Explore historical and deprecated specs without losing context.
Your specs live in git — SpecStat just reads them.
SpecStat reads openspec/index.json — a vendor-neutral, git-native format for documenting software specifications. No proprietary database. No lock-in. Your specs are always yours, in your repo.
