Delivery option
Any dataset we build can run again hourly, daily or weekly, with a diff against the last run and an alert when a field you care about moves.
Monitoring is what a scraper becomes when it runs more than once. We schedule the same extraction at the interval you choose, compare each run with the previous one and send you the differences: new rows, removed rows and changed fields. Alerts go out by webhook, email or Slack when a rule matches, such as a price dropping, a listing disappearing or a competitor posting a new role. The full snapshots still land in your storage every time.
In detail
Runs are spread out and rate-limited so a daily crawl of a large catalogue never looks like an attack. If the source starts blocking, retries back off automatically and an engineer is paged before you notice a gap in the data.
Each run produces the full snapshot plus a change set: added, removed and modified records keyed on a stable identifier. You can load only the changes into your systems and keep the snapshots as history for later questions.
Tell us the condition in plain words: price under a threshold, stock back in, new listing in a postcode, a keyword in a job title. We implement it as a rule on the diff and deliver matches to a webhook, email address or Slack channel.
Sites change layouts and protections without warning. Recurring plans include fixing the scraper when that happens, with the aim of restoring the feed before the next scheduled run. You can see the status of every run in a shared log.
Schema
Starting point only. You name the columns; we keep the names stable across every run.

As fast as the schedule runs. For hourly jobs an alert typically fires within the hour; for daily jobs the next morning. Near-real-time checks on a small set of pages are possible and quoted separately.
Only an endpoint or inbox to receive alerts. Snapshots and diffs arrive in your storage or by download link in the formats you already use, so no new tooling is needed.
It depends on page volume and frequency and is quoted per month after the first sample run. A small daily job on one site is close to the $500 project floor; large hourly jobs cost more.
Yes, at any time. Schedule and rule changes are part of the monthly plan, and we confirm every change in writing so you always know what is running.

Scraped data is only useful once it is in your systems. Every job ends with delivery to a destination you already use, in a layout you can load without cleanup.
