Website Change Detector
Snapshot any page's HTTP status, SEO tags, links, and scripts. Save it, come back later, and see exactly what changed - or compare two URLs side-by-side. Free, no account needed.
What does this tool check?
The Website Change Detector fetches a page the same way MyKavo's monitoring engine does and extracts a deterministic snapshot: HTTP status and redirect chain, title tag, meta description, canonical URL, robots meta, H1 headings, internal and external link counts, third-party scripts (like Google Analytics, Tag Manager, or Meta Pixel), HTML page weight, and response time.
Comparing two snapshots reveals the changes that most often cause silent damage: pages flipping to noindex, titles being overwritten, canonicals disappearing, analytics scripts being dropped during a rebuild, or a page suddenly returning an error status.
This free tool checks one page at a time, on demand. MyKavo does this automatically for every important page on every website you manage - on a schedule, with visual screenshot comparison, broken-link detection, and severity-ranked email alerts.

Frequently asked questions
What is a website change detector?
A website change detector captures the state of a page and compares it against a later capture, then reports what differs. This one compares two URLs, or one URL against a snapshot you took earlier, and groups the result into title, meta, heading, link, script and visible-text changes rather than dumping raw HTML at you.
How do I check if a web page has changed?
Paste the page URL and run a check to store a snapshot, then run it again later and compare. The tool shows the previous and current value side by side for every field that moved. For ongoing checks you need something that re-scans on a schedule, because a manual comparison only tells you about the moment you happened to look.
Is this website change detector free?
Yes, and it needs no account. The tool runs entirely in the browser session with no signup, no card and no trial period. A free MyKavo account adds scheduled re-scans of one website and five pages, which is what turns a one-off comparison into monitoring.
Can I monitor a page for changes automatically?
Not with this tool on its own - it compares on demand. Automatic monitoring means approving a baseline and re-scanning on a schedule, which is what a MyKavo account does: it re-checks your chosen pages daily or weekly and emails you only when something meaningful changed, with before-and-after evidence attached.
Does it work on pages behind a login?
No. The tool fetches pages the way a search engine would, so it only sees publicly reachable URLs. Pages behind authentication, paywalls or IP allowlists cannot be checked. Requests are also validated to block private and internal network addresses.
