Visual regression testing.
Screenshot testing on EU-owned infrastructure.
Catch unintended UI changes in every pull request. Your CI renders the screenshots — Difora stores, diffs and reviews them on EU-owned infrastructure, operated by an EU company.
Start free 1 project · 5,000 snapshots per month · No credit cardHow it works
No browser farm, no new test framework. Keep rendering screenshots with Playwright or Storybook in the CI you already have.
Playwright, Storybook or any tool that produces PNG files — your pipeline, your browsers, your versions. Deterministic by design.
The CLI hashes every screenshot and uploads images missing from the project. Stored identical images are reused.
Your pull request gets a pass/fail check. Changed snapshots are reviewed side-by-side with a pixel-diff overlay, then approved as the new baseline.

Your CI sends PNGs to Difora. Comparison, storage and backups run on EU-owned infrastructure. Optional repository and notification integrations receive build metadata. Public PR previews are off by default and, when enabled, may be cached outside the EU by repository image proxies.
UpCloud hosts comparison and the database in Amsterdam, with screenshot storage and backups in Frankfurt. Access uses TLS and private storage. The organization owner reviews the terms and DPA in Agreements before uploading. See the privacy policy for processing, service providers and contact details.
Compared honestly
Capture, compare, review — the core workflow is shared. Who runs the service and where your screenshots are stored make the difference.

Frequently asked questions
Can one project serve several repositories?
We recommend one project per repository. Free includes one project per organization; paid plans allow unlimited projects. Snapshot names share a project namespace, so separate repositories need distinct prefixes, such as site-a/home and site-b/home. Each build must still include the complete suite, or combine it with shards, to avoid reporting the other repository’s snapshots as removals. A project has one repository integration.
Is Difora a Chromatic or Percy alternative?
Yes. Difora offers PNG comparison, baselines, review and optional repository checks. Your CI captures the screenshots; Difora processes and stores them on EU-owned infrastructure. Hosted browser rendering and some collaboration features differ. See the feature overview and the preview-sharing details below.
Where are my screenshots stored?
Screenshot comparison, storage and backups use EU-owned infrastructure in EU data centres. Optional integrations receive build metadata. PR thumbnails are off by default; if enabled, anyone with their URL can view them and repository image proxies may cache them outside the EU.
Which tools does it work with?
Anything that produces PNG files in CI: Playwright, Storybook, Cypress, Puppeteer, Selenium. The CLI uploads only screenshots that changed and adds a pass/fail check to your GitHub pull request.
Is there a free plan?
Yes — 5,000 snapshots per month and one project, no credit card required. Paid plans start at €29 per month (excl. VAT) for teams and agencies.
Do you sign a data processing agreement (DPA)?
Yes. Your organization owner can review and accept the terms and DPA in Agreements before the first upload. The accepted version remains available to download.
