MockLock — Mockup Change Tracker

Alert and re-run visual regression when mockups silently change

Problem

Designers quietly tweak mockups during QA (a space, a font size, a copy change), turning completed work into defects, with large regressions surfacing months later. ACs merely say 'should match the approved mockups,' and nobody can trace when the mockup actually changed.

Solution

Connect Figma/mockup files, diff pixels and text to track design changes, produce a timestamped change timeline, and trigger visual regression in CI. Change evidence is ready when defect disputes arise.

Users

Frontend/QA engineers, design system maintainers, outsourced delivery teams

MVP

Figma file snapshot comparison; text and pixel diff output; change timeline page; exportable change report; simple GitHub/GitLab integration

Revenue

Per-project subscription, free for small teams, paid above 3 projects

Why now

Design handoff friction persists, existing tools do visual regression but not change provenance, and a solo dev can start with the Figma API
