Stabilization
Deterministic captures
Fonts, animations, lazy images, timers and third-party noise are frozen before every shot — so a reported diff means a real change, not a flaky run.
Self-hosted visual regression testing
See every pixel that changed
Screenshot your pages across viewports, compare them against approved baselines, and review exactly what moved — with the flaky noise stabilized out of every run.

Diffs you can trust
False positives kill visual testing. Every part of the pipeline exists to make two runs of an unchanged page come back identical.
Diff viewer
Four ways to review
Side-by-side, curtain, onion skin and a red-tint overlay — all sharing one synchronized zoom and pan, so the spot you're inspecting stays put.
Baselines
Approvals keep history
Approving a change only moves a pointer. Old shots stay on disk, so every page keeps a visual timeline you can walk back through.
Self-hosted
Your stack, your disk
Docker Compose, Postgres and content-addressed local storage. Live run updates stream over SSE. No cloud accounts, no per-screenshot pricing.
Limits, not paywalls
Nothing here goes through a checkout. This instance caps how much one browser can chew through — ask for more, or run your own copy and drop the ceiling entirely.
