Every monitor checks your URL on a schedule you set - as fast as every minute. The moment a site goes down, your team gets an email. The moment it recovers, another.

Every content change is logged permanently. Your team can review, annotate, and compare any two snapshots — building a searchable record of how pages evolve over time.
Mark changes as reviewed
One click to mark a change as reviewed. Add a note for context — "Q2 pricing update", "confirmed with legal" — so teammates know what was already looked at.
Compare any two snapshots
Tick any two versions from your history and get a full word-level diff between them. Not just before/after — compare changes from weeks or months apart.
Searchable history with date filtering
Every change ever detected is stored. Filter by date range to see exactly what happened in a given period — useful for compliance, competitive research, or post-mortems.
Built for teams who care about what their websites are doing.
Watch any page for text changes. Get a word-level diff and an AI-generated summary of exactly what was different.
Get notified the moment a monitor goes down and again when it recovers - no lag, no missed incidents.
When a page changes, a language model reads the before and after text and summarises what actually changed in plain English.
Publish a branded status page showing the uptime of your chosen monitors. Share a URL with your customers.
Invite teammates and choose exactly who gets alerted for each monitor. Per-monitor notification preferences.
Create and manage monitors programmatically. Secure API keys with full write access - integrate with your CI pipeline or Zapier.
Focus on what matters — point a monitor at a specific element like a price, headline, or article body. Everything else is ignored.
Mark changes as reviewed with optional notes — "Q2 pricing update", "flagged for legal". Keeps the feed clean and gives teammates context at a glance.
Select any two versions from your full change history and get a side-by-side word-level diff. Not just consecutive changes — any two points in time.
Content change alerts and CSS selector targeting on every plan. AI summaries and word-level diff on paid plans.
