QA Proof vs Percy

A Percy alternative for monitoring live sites, not pull requests

Percy is built for per-commit visual review inside CI — and it's good at it. QA Proof takes a different approach: it watches your live pages on a schedule, uses AI to explain what changed, and emails you when a page drifts from its approved baseline. No pipeline, no SDK, no config.

CI tools stop watching after the merge

Per-commit diffs catch the regressions your own deploys introduce. But a live page can break with no commit at all — a CMS edit, a third-party script update, an A/B test, a tag manager change. If your visual testing only runs in the pipeline, nobody is watching production. That is the gap QA Proof is built for.

Percy vs QA Proof, honestly

These are different tools for different jobs. If you need per-commit CI gating, Percy is the right tool. If you want scheduled monitoring of live sites with alerts a non-developer can read, that's QA Proof.

	Percy (BrowserStack)	QA Proof
Built for	Per-commit visual review inside CI	Scheduled monitoring of live pages
Where tests run	Your CI pipeline, via SDK and config	QA Proof’s cloud — paste a URL
Comparison method	Pixel-by-pixel diffs with a review UI	AI analysis that explains what changed and whether it matters
GitHub checks / build gating	Yes	No
Branch-based review workflow	Yes	No
Scheduled checks of production with email alerts	Not its focus	Yes — daily, weekly or monthly per monitor
Who reads the results	Developers reviewing pull requests	Anyone — scored reports with plain-language findings, PDF export
Accessibility, responsive and Figma checks included	Not part of Percy	Yes, from the same dashboard

How QA Proof works

Paste a URL

No SDK, no snapshot code, no CI config. Point QA Proof at any live page from the dashboard.

Approve a baseline

The first capture becomes the reference. When you ship an intentional redesign, approve the new version in a click.

Get alerted on drift

Monitors run daily, weekly or monthly. When the AI comparison score drops below your threshold (90 by default), an email goes out explaining what changed.

Which one fits your workflow?

Percy is the right choice when…

You want every pull request gated on visual diffs before merge
You need per-commit snapshots tied to your git history
Your team lives in a branch-based review workflow
Deep CI and GitHub integration is a requirement

QA Proof fits better when…

You want to monitor live sites — including ones you don't deploy, like client or CMS-driven sites
You'd rather paste a URL than maintain pipeline config
Non-developers need to read the results — scored reports with plain-language findings and PDF export
You want accessibility (WCAG 2.1), responsive and Figma design-fidelity checks from the same dashboard

Common questions

No — and we would rather say that upfront. Percy (by BrowserStack) is built for per-commit visual review inside your CI pipeline: snapshots on every pull request, a diff review workflow, and GitHub status checks that gate merges. QA Proof has none of that. It monitors live URLs on a schedule and emails you when a page drifts from its approved baseline. If you need per-commit CI gating, Percy is the right tool.

There is no CI/CD pipeline integration — no GitHub checks, no build-step gating, no branch-based review. QA Proof does have a REST API with API keys, so you can trigger tests from your own scripts if you want custom automation, but the core workflow is scheduled monitoring of live pages.

Yes, and the combination makes sense: Percy catches regressions your own commits introduce before they merge, while QA Proof watches the live site for changes that never go through your pipeline — CMS edits, third-party scripts, plugin updates.

A pixel diff tells you that pixels changed; the review is on you. QA Proof’s AI explains what changed and whether it matters — a moved button versus a re-rendered font — and masks dynamic content, so rotating banners and feeds don’t generate noise. Reports are scored 0–100 with findings and recommendations that non-developers can read, and you can export them as PDF.
