PagePing

About

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.
