Visidaily automates full-page screenshot comparison across 4 viewports. Here\'s exactly what happens from sign-up to your first alert.
Try it freeEnter a URL and give the site a name. Pick how often you want checks to run — every 6 hours, 12 hours, daily or weekly. That's the only configuration required.
Visidaily supports any publicly accessible URL. Behind Cloudflare, a load balancer, or a CDN? No problem — the capture engine handles it.
List the paths that matter — homepage, pricing, contact, checkout. Each page is monitored independently across all viewports.
You can add as many pages as your plan allows. Start with the ones that matter most to your clients or users.
The first time Visidaily runs, it captures a full-page screenshot at 4 viewport sizes: 1920px, 1280px, 390px (iPhone), and 360px (Galaxy). This becomes your baseline.
The stealth capture engine dismisses cookie banners automatically and waits for JS-heavy content to render before taking the shot.
On each scheduled check, Visidaily takes a fresh screenshot and compares it pixel-for-pixel against the baseline. Even a 0.1% change is recorded.
Changed pixels are highlighted in magenta. You can view the baseline, current screenshot and diff overlay side-by-side in a zoomable lightbox.
When a change is detected, Visidaily sends an alert via email and/or Slack. Crucially, it only alerts on status transitions — PASS to FAIL — so you never get spammed.
If a page is already failing, you won't get a second alert until it recovers and breaks again. Recovery notifications work the same way.
Open the diff, inspect the magenta overlay, and decide. If the change was intentional — a redesign, a new banner — accept it and it becomes the new baseline.
You can also upload a custom baseline image, or promote any historical screenshot to baseline. Your team can collaborate on reviews.
Full-page scroll capture — nothing below the fold is missed.

Baseline
The last known-good screenshot. This is what your page should look like.
Current
The freshest screenshot from this check run.
Diff overlay
Changed pixels highlighted in magenta. Size of the magenta area maps directly to the diff percentage.
Sites protected by Cloudflare, bot scores or JS fingerprinting render normally. Visidaily patches every detectable headless signal.

How long does a check take?
Most pages are captured and compared in under 30 seconds. JS-heavy pages with long render times may take up to 60 seconds. The dashboard shows live progress.
What if my site has a cookie banner?
Visidaily automatically clicks common Accept / Accept All buttons before taking the screenshot so cookie banners never appear in your baseline or diffs.
Does it work with Cloudflare or other bot protection?
Yes. The stealth capture engine patches all headless browser signals — navigator.webdriver, automation flags, WebGL vendor, plugins — so your site renders as it would for a real user.
What counts as a "change"?
Any pixel difference above a configurable threshold is flagged as a FAIL. By default this catches layout shifts, colour changes, missing images, and font rendering differences.
Can I monitor pages behind a login?
Currently Visidaily monitors publicly accessible URLs. Support for authenticated pages is on the roadmap.
What happens to my screenshots after 14 days?
Older check records and screenshots are automatically cleaned up after your plan's retention period (7 days on Free, 14 days on Starter and Pro).
Free plan available. First baseline ready in under 5 minutes.
