START WITH A CLEAR TARGET
A guided builder that shows what you’ll watch.
Paste a public URL, choose a goal, then select the content from a captured page preview. Click an element in the image or choose it from the text list. Confirm the extracted value before you start.
The final step brings your targets, rules, schedule, notifications, and estimated monthly checks together. Advanced selectors are available when you need more control.
Explore the monitor setup guide →START FROM THE PAGE YOU’RE ON
Point, click, and create a monitor in Chrome.
The PageFluxer Chrome extension lets you select an element directly on a public webpage and choose a content, price, stock, or new-listing rule. Continue to the website with your draft already filled in.
Explore the Chrome extension →TWO WAYS TO LOAD THE PAGE
HTML checks or Browser checks.
The loading method determines how PageFluxer gets the content. The targets and rules determine what it watches.
Browser checks
Run JavaScript in a browser to capture dynamically loaded content.
Use this when the content you expect is missing from an HTML preview. Included on Starter and Pro, with a one-time 7-day trial on Free.
Both methods support text, price, availability, and new-listing rules. HTML and Browser checks have separate usage allowances. Free’s browser trial covers 1 monitor and up to 168 hourly attempts; it starts with your first saved browser monitor.
Supported pages, loading limits, and troubleshooting →THE CHANGE YOU ACTUALLY CARE ABOUT
Choose the rule behind the alert.
All plans include the same target types. Start broad or narrow your monitor to a specific value, phrase, or list.
Text & page content
Track any text change, a phrase starting to appear, or a phrase disappearing. Select the whole page, main content, or one specific element.
Prices
Alert on any numeric price change, a price drop, or crossing below your chosen amount. Confirm the currency and decimal format in the preview.
Availability
Track when a product becomes available or unavailable using its stock wording. Unknown or missing content stays a check issue, preserving the last successful values.
New listings
Watch for new matching links in a job list, announcements index, or product listing. Narrow matches with a literal phrase in the link text or URL.
A threshold such as “below $30” alerts when the condition becomes true. It doesn’t repeat on every check while the price stays below $30. Your confirmed preview sets the starting baseline; existing matches do not send an initial alert.
AFTER THE CHANGE
The context, the timing, and the next step.
Monitoring is more useful when you can review an update and choose how it reaches you.
Change history & highlighted diffs
Open a monitor’s timeline to see captured changes. Compare before-and-after text and revisit retained versions when you need context.
- Additions and removals highlighted in text diffs.
- The last successful capture remains the comparison baseline.
- Up to 7, 30, or 90 days of history by plan, subject to storage allowances.
A watch list you can keep organized
Give monitors recognizable names, group them with labels, and find the page you need without scanning every URL.
- Search, filters, and change-review status.
- Bulk actions for managing several monitors.
- Monitor details with check status, targets, and notification settings.
Alerts that fit your day
Choose email for each matching change, an hourly digest, or a daily digest. Keep check frequency separate from notification frequency.
- Daily digests use your saved time and timezone.
- Starter and Pro add quiet hours and minimum email intervals.
- Paid plans support per-monitor notification schedules.
Quiet hours delay email while checks and history continue. Monthly email allowances apply; after the allowance, changes are combined into a daily account digest.
Understand notification allowances →Signed webhooks for your own tools
Add one HTTPS endpoint at account level, then enable webhook delivery on the monitors you want to connect.
- Matching change events with monitor details and bounded excerpts.
- Signature verification, delivery history, and retry handling.
- Delivery independent of email quiet hours and digests.
A SCHEDULE YOU CAN UNDERSTAND
See what your monitors use.
HTML checks can run as often as every 60 minutes on Free, 15 minutes on Starter, and 5 minutes on Pro. Browser checks run at 60-minute intervals or slower on Starter and 15-minute intervals or slower on Pro.
Monitor slots and check allowances work together. Your setup estimate and usage page help you balance faster schedules with a larger watch list. Allowances are shared across the account and reset each UTC calendar month. Capacity and website backoff can delay checks.

Build monitoring into your own workflow.
Create and manage monitors, retrieve change history, read usage, and request checks through the public API. Scoped, revocable tokens give each integration only the access it needs.
Pro includes 60 API requests/minute and 5,000/day across the account. Up to 20 manual check requests/day use your existing check allowance; API access does not add rendering credits.
