FAQ
How does SnapDiff capture screenshots?
SnapDiff uses a headless browser to render your pages at specified viewports and stores the images in cloud storage. You trigger captures via our REST API or CI webhook.
What counts as a visual regression?
Any pixel-level difference above your configured threshold — layout shifts, color changes, missing components, or broken styles — is flagged and shown in the diff viewer.
Can I integrate with my existing CI/CD pipeline?
Yes. SnapDiff provides a simple webhook endpoint and CLI tool that fits into GitHub Actions, GitLab CI, CircleCI, or any pipeline that can make an HTTP request.
