Monitor competitor pricing, job postings, and landing pages. FlyPython filters out noise and sends you field-level diffs — not just "the page changed."
Get alerts in Slack, email, or webhook when prices drop, jobs are posted, or messaging pivots.
{
"event": "page.changed",
"url": "https://competitor.com/pricing",
"change_type": "price_drop",
"confidence": 0.97,
"diff": {
"price": { "before": 129.00, "after": 99.00 },

}Not just “the page changed.”
“Price dropped 23%. Stock unchanged.”
Field-level structured diffs, classified and delivered as webhook events.
Built for teams tracking:
Use cases
Get alerted when the fields that matter actually change — not when timestamps, ads, or tokens shift.
Track competitor prices, promotions, and plan changes. Get alerted the same day a rival undercuts you.
Example diff
“Price dropped 23% ($129 → $99)”
Watch career pages for new roles, department expansions, and hiring velocity. Spot growth signals early.
Example diff
“3 new "Engineering" roles added in London”
Detect headline changes, CTA updates, hero swaps, and pricing-block moves. See messaging pivots in real time.
Example diff
“Headline changed: "Old message" → "New message"”
How It Works
FlyPython handles the web-reading loop so your team can work with stable events instead of brittle page checks.
Choose competitor pricing, job postings, landing pages, or describe what you want to watch in plain English.
Enter the URLs to monitor, how often to check, and where to deliver alerts — Slack, email, webhook, or all three.
When a meaningful field changes, receive a signed webhook with before/after values, confidence, and a short summary.
Each event includes the changed fields, before/after values, a confidence score, and a human-readable summary. Delivery is signed, retried, and logged.
