Price & Competitor Monitoring
Track prices and competitor changes across any site and get alerted the moment something moves — scheduled, hands-free, and cheap to run often.
Prices, plans and competitor pages change without warning, and by the time someone notices manually the moment has passed. Prompteryx watches the pages that matter on whatever cadence you choose, compares each reading against your threshold or the last value, and pings you the instant something moves.
Because cloud browser time is billed by the second, checking dozens of pages every hour stays inexpensive — the kind of high-frequency monitoring that gets costly fast when every short run is rounded up to a whole minute.
The problem
Manual price checking doesn't scale and never catches changes in time, while frequent automated checks become expensive under whole-minute billing — so teams check too rarely and miss the moment.
How it works in Prompteryx
List the product or competitor pages and the threshold or change that should trigger an alert.
Prompteryx opens each page in a real browser on your cadence and reads the current value with a self-healing selector.
Evaluate each reading against your threshold or the previous value to decide if it's noteworthy.
Send a Slack message, email or any integration the moment a change matters — with the old and new values.
Log every reading to a sheet and record each run as video for a verifiable price history.

Why Prompteryx for this
Per-second billing
Each check is a few seconds of browser time, billed by the second — so monitoring many pages every hour costs a fraction of whole-minute pricing.
Scheduled, server-side
Checks run on our servers on your cadence; nothing has to stay open on your machine.
Instant alerts anywhere
Route alerts to Slack, email, SMS or any of 3,000+ apps the instant a change matters.
Verifiable history
Every reading is logged and every run recorded, so a price claim can be backed by the actual page view.
Real-life examples
Watch competitor product pages hourly and alert the pricing team in Slack the moment one undercuts you.
Monitor an out-of-stock item and notify a buyer the instant it returns.
Detect when a competitor changes their pricing page and capture a screenshot of the new version.
Frequently asked questions
How often can I check without it getting expensive?
As often as hourly across many pages. Each check is only a few seconds of browser time and billing is per-second, so high-frequency monitoring stays cheap compared with whole-minute pricing.
How do I get alerted?
Through any connected app — Slack, email, SMS, Microsoft Teams and 3,000+ others — with the old and new values included, the moment a change crosses your rule.
Can I prove a price was what I say it was?
Yes. Every reading is logged to a sheet and every run is recorded as video, giving you a verifiable history of exactly what each page showed and when.
