ParkWhiz Web Reservation Reminder

WHAT IT DOES

ParkWhiz Web Reservation Reminder reads reservation details and arrival windows from your ParkWhiz account and displays a floating reservation reminder badge showing upcoming reservations and a countdown timer. The badge shows the reservation location, date and time, and a countdown timer displaying days, hours, and minutes remaining until the reservation starts. The countdown turns red and pulses when the reservation is within 4 hours. A status indicator shows Active, Upcoming, or Ended. The extension tracks reservation history per user, storing each reservation with a timestamp. When a reservation is approaching within 4 hours, a desktop notification is triggered. The panel displays your upcoming reservation, countdown, status, and reservation history.

WHERE IT RUNS

This extension works on all ParkWhiz pages at parkwhiz.com and its subdomains, specifically on account pages where reservation details and arrival windows are displayed. It runs on the main account page, the reservations page, the booking page, and any page displaying reservation information. The extension operates entirely within your browser and does not access ParkWhiz's servers directly—it reads only what is visible on the page you are viewing. It works alongside the free BotGentz extension, which provides the necessary scripting environment.

HOW TO USE

Install the extension, then navigate to parkwhiz.com and log in to your account. The extension automatically creates a floating reservation reminder badge on the page. Click the extension's icon in your browser toolbar to open the settings panel. Use the "Show Overlay" / "Hide Overlay" button to toggle the badge visibility. The badge shows your upcoming reservation, countdown timer, and status. Use the "Refresh" button to manually update the badge with the latest reservation information. The "Show countdown timer" toggle controls whether the countdown appears. The "Upcoming reservation notifications" toggle controls desktop notifications when reservations are approaching. Adjust the overlay transparency using the opacity dropdown (70%, 82%, 92%, or 100%). Drag the badge by clicking and holding anywhere inside it. Resize it by dragging the bottom-right corner. Close the badge with the × button.

RESERVATION DATA EXTRACTION WITH DATE PARSING AND COUNTDOWN CALCULATION

Unlike simple reservation display tools, this extension uses a multi-selector extraction engine to find reservation items, locations, dates, and status from ParkWhiz's varying page structures. It searches for reservation items using multiple selector patterns (.reservation-item, .booking-item, .order-item) and falls back to text parsing. Locations are extracted from location selectors. Dates and times are extracted from date-time selectors using date parsing that handles multiple formats. Reservation status is detected using status elements and keyword matching (active, confirmed, upcoming, scheduled, ended, completed, past). The countdown timer calculates days, hours, and minutes remaining until the reservation start time using real-time Date comparisons. The timer updates on each refresh and shows urgency when less than 4 hours remain. Per-user reservation history is stored as a key-value object where keys are user identifiers and values are arrays of reservation records with timestamps, limited to 20 entries per user. Upcoming reservation notifications trigger when a reservation is within 4 hours, with a one-hour cooldown.

THE PANEL

The panel supports drag-to-move anywhere on the page. It remembers its position per site, so it stays where you placed it on parkwhiz.com. Click the panel header to collapse it down to just the minimized bubble, or click the expand handle to show the full panel. The panel can be resized by dragging the bottom-right corner. Press the Escape key to close the expanded panel and return to the minimized state. All panel settings, including position, size, collapsed state, opacity, countdown visibility, notification preference, and reservation history, are saved per site and persist across browsing sessions.

PLEASE NOTE

This extension requires the free BotGentz extension to be installed and active, as it provides the underlying DOM injection and script execution environment. ParkWhiz's website changes periodically, and reservation element structures, class names, and page layouts may be updated. When that happens, the extension may stop detecting reservation data until an update is released. The extension stores your overlay position, size, opacity, visibility, countdown preference, notification preference, and per-user reservation history locally in your browser's storage using GM_setValue. Reservation history is stored as a key-value object where keys are user identifiers and values are arrays of reservation records. The reservation data displayed is read from the page—the extension does not access ParkWhiz's internal reservation data. Always verify with ParkWhiz directly for the most accurate reservation information. No data is ever sent to any server, and no personal information is collected. You can clear all stored settings at any time by clearing your browser data for parkwhiz.com.
