Sneaker Marketplace Release Calendar Overlay

WHAT IT DOES

Sneaker Marketplace Release Calendar Overlay scans the current page for sneaker release information, extracting shoe names, colorways, release dates, retail prices, and resale values from marketplace pages and sneaker news sites. The floating panel shows an upcoming release calendar with countdown timers, retail-to-resale price comparisons, and hype indicators. Filter by brand (Nike, Adidas, New Balance, etc.), silhouette type, and time window. Add personal reminders and notes to releases. Export release calendar data as CSV or text for collection planning. Releases with high resale potential are highlighted, and release price trends are tracked.

WHERE IT RUNS

Works on any sneaker marketplace page, including StockX, GOAT, Sneaker News, Sole Collector, and other sneaker release platforms. The script detects release information using common selectors and pattern matching. It works best on pages with structured release data containing shoe names, dates, and prices.

HOW TO USE

The panel displays an upcoming release calendar with countdown timers showing days and hours until each release. Each release shows its hype level (High/Medium/Low) with color-coded indicators. Retail and resale prices are shown side-by-side with percentage differences. Click "Scan Releases" to detect all releases from the current page. Add reminders with notes to any release for personal tracking. Export the calendar data as text for collection planning. The panel automatically filters releases within the configured time window (default 30 days).

MECHANISM — RELEASE EXTRACTION WITH HYPE SCORE CALCULATION

The script extracts sneaker releases using a multi-strategy approach. It first attempts to find release containers using common selectors (.release, .release-item, .sneaker-release). From each container, it extracts the shoe name, release date, retail price, and resale price using targeted sub-selectors. The brand is detected by matching against a database of known sneaker brands. The hype score is calculated based on multiple factors: presence of keywords (limited, exclusive, collab), brand prestige (Jordan, Yeezy add 15 points), and resale-to-retail ratio (over 1.5x adds 15 points). The hype level is categorized as High (70+), Medium (40-69), or Low (below 40). Countdown timers are calculated from the release date and updated in real-time.

THE PANEL

The floating panel is fully draggable and remembers its position per domain. Click the minimize button to collapse it to a small bubble, or press Escape to hide it. The panel automatically adjusts to different screen sizes and can be resized to show more content. All settings, including time window and reminders, are saved per domain. The panel integrates smoothly with any page layout using the BGPanel framework, maintaining clean separation from page content.

PLEASE NOTE

This script requires the free BotGentz extension to run. It does not send any data to external servers; all extracted release data, reminders, and settings remain entirely local to your browser using GM_setValue. The script never reads password fields, hidden inputs, or file inputs. It stores only shoe names, brands, dates, prices, and user-entered reminders from publicly visible page content. Release detection depends on the page structure; if releases are not detected, use the "Scan Releases" button to refresh extraction. Resale prices are estimates from public listings and may vary. Data persists across browser sessions and is isolated per browser profile.
