Storage Unit Site Size Comparison Overlay

WHAT IT DOES

Storage Unit Site Size Comparison Overlay scans the current page for self-storage unit listings, extracting unit sizes, prices, availability, and features from storage facility websites. The floating panel compares unit sizes side-by-side with price per square foot, total cost, and value rankings. Visual size comparison using scaled rectangles highlights the best value units. Filtering by size range and price helps narrow down options. Export comparison data as CSV or text for reference. Price trends by unit size are tracked, and units with the best price-to-size ratio are highlighted.

WHERE IT RUNS

Works on any self-storage facility website, including major storage companies and local facility pages. The script detects storage unit listings using common selectors and can also fall back to general card-like elements. It works best on pages with structured unit listings containing size, price, and availability information.

HOW TO USE

The panel displays all detected storage units with their size, price, price per square foot, and availability. Click "Scan Units" to detect all units from the current page. Visual bars show relative unit sizes, and the best value unit is highlighted with a "BEST VALUE" badge. Use the size filter to narrow the range of units shown. Each unit shows its rank and value rating (Best, Good, Average, Poor) with color coding. Export the data as text for easy reference. The panel automatically scans on load if enabled.

MECHANISM — UNIT EXTRACTION WITH VALUE RANK CALCULATION

The script extracts storage units using a multi-strategy approach. It first attempts to find unit containers using common selectors (.unit, .storage-unit, .unit-item). From each container, it extracts unit size using size selectors and price using price selectors. Features and availability are extracted when available. The price per square foot is calculated as price / size. The value ranking system compares all units by price per square foot, then assigns a rank: Best (lowest 25%), Good (25-50%), Average (50-75%), or Poor (75-100%). The visual size comparison scales rectangles proportionally to unit size, making it easy to compare sizes at a glance. All extraction runs client-side with no network calls.

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 size filters, 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 unit data 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 unit sizes, prices, features, and availability from publicly visible page content. Unit detection depends on the page structure; if units are not detected, use the "Scan Units" button to refresh extraction. Price comparisons are based on the current page data and should be used as a reference. Data persists across browser sessions and is isolated per browser profile.
