Website Change Monitor

Watch any web page — or one element on it — and get told only when something really changes.

Most "change detection" tools fire every single run because pages contain timestamps, session tokens and view counters that move on their own. This one strips that noise before comparing, so an alert means an actual edit.

What it watches

Visible text of a whole page or a section (default)
A CSS selector — one price, one headline, one status badge
An attribute — href, content, data-*
A JSON-LD field — e.g. offers.price on a product
A meta tag — og:title, description
A regex — anything else

What it ignores on purpose

Timestamps · ISO dates · epoch numbers · CSRF tokens · nonces · session ids · UUIDs · cache-busting query strings · "3 hours ago" · "1,204 views". Change one of those and this Actor stays quiet.

Input

{
  "urls": [
    "https://example.com/pricing",
    { "url": "https://competitor.com/plans", "selector": ".price-table", "label": "competitor-pricing" }
  ],
  "mode": "text",
  "webhookUrl": "https://hooks.slack.com/services/XXX"
}

Per-URL objects override the global mode, selector, attr, ldType, path and pattern.

Output

One dataset row per target:

field	meaning
`status`	`FIRST_RUN` · `UNCHANGED` · `TEXT_CHANGED` · `VALUE_CHANGED` · `ERROR` · `NO_VALUE`
`changed`	boolean — the field to filter on
`value` / `previousValue`	now vs before
`detail.snippets`	the exact words added and removed
`hash` / `previousHash`	stable fingerprints

A failed page load is reported as ERROR and is never counted as a change.

Typical uses

Competitor pricing and feature pages
Terms of service / privacy policy edits (compliance)
Government or regulator notice pages
Documentation and changelog pages
Job, tender or grant listing pages
Any page a client pays you to keep an eye on

Schedule it

This Actor is built to run on a schedule. Daily is right for most pages; hourly for prices and stock. Point webhookUrl at Slack, Discord, Zapier or Make and you never open Apify again.
