SaaS Pricing Monitor

Track SaaS pricing pages and generate a clean diff of what changed between runs.

What it does

This Actor monitors one or more public pricing pages, extracts the observed plan data, and compares the current snapshot against the previous one stored in Apify Key-Value Store.

It is designed to answer questions like:

• Did the monthly price change?
• Was a new plan added or removed?
• Did the free tier or trial terms change?
• Did plan features or billing periods change?

Notes

The Actor is intentionally built for pricing pages, not generic crawling. It favors deterministic extraction, low operational cost, and a stable output contract that can feed alerts, dashboards, and downstream analysis.
