An open-source React tool that stores product tours as typed data and checks in CI whether their UI anchors still exist.

Why it surfaced

Cairn turns a familiar product-tour failure into a build error: rename or delete a button, and `cairn check` can catch the broken tour before a customer does. The site makes the case with a runnable playground, concrete code examples, and a notably clear promise: “Product tours that fail your build, not your users.”
