Paste a public URL, or watch a signed-in page from Chrome. You get a visual and text diff when the region you picked actually changes.
Not sure what to track?
Paste a URL above and click Go. Public pages run in the cloud; sign-in pages use your Chrome extension.
0/20None yet — the full page is watched
Use cases
Competitor pricing, policy wording, stock badges, job lists, dockets, and release notes all start the same way. Paste the URL, pick the region, get the diff. Each label below is a full page, not a chip.
All use casesHow it works
1Step 1
Public pages run in the cloud. Private and local addresses are blocked so watches stay on the open web.
2Step 2
Click or draw the block that should move: a price, a clause, a stock badge. Leave the rest of the layout out.
3Step 3
Visual and text diffs land in the workspace. Noise is dropped. Real edits get an alert.
Product
One monitor records a screenshot and the copy. A legal clause edit and a banner swap do not look the same in the timeline.
That is the usual gap with a Visualping-style screenshot or a Distill.io HTML watch used alone. You still get the picture. You also get the sentence that changed, in one timeline.
Ignore nav, cookies, and carousels. Watch the price, clause, or badge that actually decides the outcome.
Pages behind a login run in your browser. Cloud workers never receive those cookies.
Group watches by client, product, or team. Filter the list without rebuilding monitors.
Email, Slack, Telegram, Teams, Discord, signed webhooks, or an API and MCP server. Throttle repeats and mute noisy watches.
Monitor URLs pass SSRF checks. Private and localhost addresses are blocked. Captures stay inside your workspace.
Compare
Those tools watch pages. WebURLTracker is the better solution when you need the screenshot and the copy, Local Chrome for signed-in URLs, and folders the team can actually share. Read the full pages if you are switching.
Alerts and integrations
Team channels on every plan. Signed webhooks for your own systems. An API and MCP server so scripts and AI assistants can read what changed.
Every plan
Email, Slack, Microsoft Teams, Discord, and Telegram. The alert says what changed, not just that something did.
Paid plans
JSON to your endpoint for every alert, change, or monitor error. Each request is signed so you can trust it.

Free tiers for change detection are useful, but not interchangeable. Here is what you get before you pay.
7 September 2026
Cloud monitors cannot see your session. The Chrome extension checks in the browser you already signed into.
5 September 2026
Three overlapping tools, three different defaults. Pick the default that matches the job, then look at price.

An alert without a region is a screenshot of yesterday's ad unit. Wire the watch, then wire the channel.
1 September 2026
Counsel needs the clause that moved, not another screenshot of a restyled policy template.

A screenshot without the sentence is incomplete. Keep visual and text diffs on the same monitor.
