Normal users cannot easily see how old a property listing is, whether the price has changed, or when it was first published. Rote Kapsel makes this hidden metadata visible through on-page indicators, helping users make better-informed decisions during their apartment/house search.

User installs extension → browses supported real estate portals → extension content scripts detect property listings on the page → sends listing GUIDs and price data to backend API → receives status indicators (NEW/UP/DOWN/SAME) → displays colored indicator dots on listing images and popup boxes with metadata when hovered/clicked

Target users: Apartment and house seekers in Germany / Real estate buyers and renters across European markets (Germany, Austria, Switzerland, Italy, Spain) / Users of popular classified sites like ImmobilienScout24, Kleinanzeigen, Immowelt

Source code is heavily minified/bundled (webpack), making deep code logic analysis difficult - large content scripts are ~270KB single-line bundles
Cannot fully inspect the React component tree in the 4 main content scripts (immobilienscout24, immowelt, kleinanzeigen, willhaben) due to minification
The backend API (prd.secseek.com) behavior cannot be fully verified from client-side code alone - could potentially serve paid tiers in the future

Monetization

No paid features detected

No premium, subscription, payment, stripe, pricing, upgrade, or billing keywords found in any source file. The store description describes it as 'kostenlos' (free) - 'kostenlosen Immobilienhilfstool'. No feature gating, tier system, payment platform integration, or upgrade prompts detected in the code. The 'pro' keyword hits are all false positives from React/Redux library production minified code (e.g., 'react.production.min.js'). The 'license' hits are MIT license headers in React source code, not commercial license checks.

Reason: The Chrome Web Store description explicitly states 'Rote Kapsel ist für alle nutzbar ★ohne Registrierung, ohne Tracking!★' (usable by everyone without registration, without tracking). No login UI, authentication flows, token handling, or credential storage found in any source file. The 'login' keyword search returned zero results. The extension's API calls to prd.secseek.com send property entity data without any authentication headers. Content scripts run on public real estate listing pages and do not require users to be logged in to the extension.
