PagePing

PagePing watches the webpages you already have open and pings you the moment the part you care about changes — a price, a "back in stock", a new appointment slot, a keyword, even a visual change. Pick the exact spot on the page, choose a rule, and walk away. 🔒 100% PRIVATE BY DESIGN No server. No AI. No accounts. No cloud sync. No analytics. Everything stays in your browser using local storage only — your data never leaves your device. 🎯 POINT-AND-WATCH • Click "Select Area to Watch" and pick any element — price, status, button. • Or watch the whole page in one tap. • A reliable selector is generated automatically, with fallbacks if the site changes its layout. Re-pick anytime. 🔔 SMART ALERT RULES • Price drops / rises / below or above a target / changes by a % • Any number changes (followers, seats left, ETA…) • Back in stock / sold out / availability changes • A keyword appears or disappears • A button becomes enabled or visible • Text matches a custom pattern (regex) • The area simply looks different (visual change) • Combine two rules with AND / OR, and watch several elements at once. ⚙️ YOU'RE IN CONTROL • Check every 30s up to once a day — or a custom interval. • Run for 15 min to 24 hours, custom, or until you stop it. • Smart backoff slows checks on quiet pages and speeds up on change. • "Double-check before alerting" kills false pings from page flicker. • Quiet hours, snooze, per-watcher cooldown, notify-once or every change. 📊 SEE WHAT CHANGED • Desktop notification with Open / Snooze buttons (+ optional sound & badge). • Inbox feed of every past ping — with a snapshot thumbnail of what changed. • Price/number history with a sparkline, min / max / average. • Command palette (⌘K / Ctrl+K) to jump anywhere fast. 🧰 POWER TOOLS • Quick-start templates: flight price, tickets, product stock, appointment slots, competitor price. • Noise filters ignore whitespace, timestamps, countdowns, cookie banners & ads. • Export watchers (JSON) and history (CSV); import a backup. • Optional LOCAL webhook (localhost-only, off by default) for Home Assistant, ntfy, or your own scripts. • Auto-reopen a watched tab if it closes; graceful handling of login walls and CAPTCHAs (it pauses out of respect — it never tries to bypass them). Works on Chrome and Edge (Chromium / Manifest V3), Windows and macOS. PagePing is for the things you'd otherwise refresh by hand: concert tickets, flight fares, restock pages, visa/DMV slots, competitor prices, doc updates. Set it once. Get pinged. Move on.
