Know when your competitors change their pricing.
PlanSentry monitors SaaS pricing pages on your schedule and turns page changes into useful signals: price moves, plan changes, limits, packaging updates, and feature shifts.
Stop manually checking pricing pages.
PlanSentry is intentionally narrow. It monitors the pages that matter, stores history, filters pricing-relevant content, and tells you what changed.
Add a pricing page
Paste a competitor URL and capture the first baseline immediately.
Choose a cadence
Check hourly, every 6 or 12 hours, daily, or weekly.
Review the signal
See concise summaries, raw added/removed lines, severity, history, and review state.
Useful intelligence, not generic page diffs.
Pricing-focused detection
Extraction prioritizes prices, plan names, billing periods, seats, usage, limits, and packaging language instead of every cosmetic page edit.
Outbound alerts
Webhook support lets detected changes flow into Slack, Discord, Zapier, Make, n8n, or your own systems.
History and review state
Keep snapshots, inspect previous changes, mark items reviewed, and export your data.
Secure by design
Account authentication, server-side database operations, RLS, rate limiting, SSRF defenses, and hardened browser headers.
Start small. Scale monitoring when it proves useful.
