MarketFlip — Marketplace Deal Finder & Price Check

MarketFlip overlays every Facebook Marketplace listing with real-time deal scoring and the smart filters resellers actually use. Spot underpriced cars, motorcycles, phones, gaming consoles, graphics cards, and more — without opening every listing. Free, open-source, and runs 100% in your browser. No accounts, no subscription, no telemetry. ⚠ Currently optimized for vehicles and consumer electronics. Other categories are detected and tagged but may not produce automatic value scores. Listing accuracy depends on how the seller wrote the title and description — verify pricing before making any offer. ────────────── WHAT YOU GET ────────────── 🎯 DEAL SCORE BADGE on every Marketplace card — STEAL / GOOD / FAIR / HIGH based on % below market value. Stop opening 30 listings to find one good one. 🚗 AUTO VEHICLE PRICING via public Kelley Blue Book pages — Trade-in and Private Party values for cars, trucks, SUVs, vans, motorcycles, and ATVs. Mileage-aware, year-fallback, with title-brand adjustments built in. 📱 ELECTRONICS PRICING via public Swappa pages — covers smartphones, laptops, tablets, smartwatches, audio devices, gaming consoles, graphics cards, and smart-home devices. 🏷️ TITLE-BRAND ADJUSTMENTS — vehicle values automatically discount for salvage, rebuilt, flood, fire damage, frame damage, lemon-law buyback, theft recovery, and missing-title listings. Every multiplier is tunable in settings. 🚩 80+ FLAG CHIPS — instantly see if a listing has red flags (salvage, parts only, water damage, locked devices, "as-is", down-payment financing) or green flags (clean title, mint, sealed in box, factory unlocked, full kit). 📲 TELEGRAM ALERTS — connect a free Telegram bot via the in-dashboard wizard and get a phone push whenever a saved search catches a deal at or above your minimum score. Includes the photo, value comparison, and a one-tap link to the listing. ⏱ AUTO-SEARCH — saved searches optionally scan Marketplace in the background and surface new matches as desktop notifications. Three pacing modes (Safe / Normal / Risky) tune how aggressively MarketFlip fetches listings. 🔍 SMART KEYWORD FILTERING — saved searches support positive AND negative keywords. Include "ninja 600" to find sport bikes; exclude "salvage" or "as-is" to filter out projects. Adjacency-aware matching prevents false positives. 📦 BULK ACTIONS — select multiple cards to star, archive, copy URLs to clipboard, or export an 80-column CSV with full listing details for offline analysis. 📍 DISTANCE FROM HOME — set your location once, see every listing's distance from you, and sort by closest first. Built-in geocoding for major US metros. 🚨 SCAM DETECTION — flags suspicious listings using multiple signals: deeply-below-market prices, impossible model years, sketchy payment language, multiple red flags compounding. 📊 LISTING-FACTS TAGS — rentals, apparel, home sales, furniture, ISO posts, and free items get categorized chips with extracted metadata (bedroom count, square footage, clothing size) so the dashboard isn't a wall of "OTHER" badges. ⏰ LISTING AGE INDICATOR — fresh / aging / stale / dead 💀 color tiers help spot motivated sellers and pickup-only stale listings. ✉ ONE-CLICK QUICK REPLIES — built-in message templates ("Is this still available?", "What condition?", "Do you deliver?"). Auto-send is opt-in. ⭐ STAR & WATCH listings to revisit. Watching auto-archives when a listing is marked sold. Price-drop history surfaces when a seller cuts the asking price. 🛡️ THREE PACING MODES — Safe / Normal / Risky. Safe minimizes background fetch load (good after a temporary block). Risky pushes harder for the freshest data. Each mode tunes auto-search interval, fetch concurrency, scroll depth, and cache windows in one click. 🔄 SMART CACHING — recently-fetched listings load instantly without re-fetching. Three-tier cache strategy keeps request volume low while still catching price drops on listings you're actively watching. 🎓 GUIDED TOUR — first-time users get a 90-second walkthrough of the dashboard layout. Replay any time from Settings. ────────────── PRIVACY-FIRST ────────────── ✓ 100% local — runs entirely in your browser ✓ No accounts, no telemetry, no analytics, no ads ✓ Settings, listings, and saved searches stored in IndexedDB on your device ✓ One-click cache wipe from the popup or dashboard The extension only contacts the public pages you'd otherwise visit yourself: the Marketplace listings you're already browsing, plus public vehicle and electronics value pages used to compute deal scores. Optional Telegram alerts use your own bot — messages go directly from your browser to Telegram, never through any MarketFlip server. Never sells, transmits, or shares your data. ────────────── DEEPLY CUSTOMIZABLE ────────────── The dashboard's settings panel exposes: • STEAL / GOOD / FAIR / HIGH score thresholds • Title-brand discount multipliers — salvage, rebuilt, flood, fire, frame damage, no-title / bill-of-sale, lemon-law buyback, theft recovery • Listing-age tier boundaries — fresh / aging / stale day cutoffs • Mileage adjustment behavior for vehicles • Suspicious-listing detection threshold • Default sort order (newest, cheapest, best-deal-score, closest) • Card density (comfortable or compact) • Theme (auto / light / dark) • Three scrape pacing modes (Safe / Normal / Risky) • Per-saved-search auto-search opt-in, notification preferences, deal-label filters • Telegram alert minimum score and pause toggle ────────────── WHO THIS IS FOR ────────────── • Used-car flippers — find underpriced cars, trucks, SUVs before they sell • Motorcycle resellers — KBB-aware pricing for sport bikes, cruisers, dual-sports, dirt bikes • Tech resellers — consumer-electronics arbitrage powered by public marketplace data • Marketplace power users — scan rentals, furniture, free items, and apparel with categorized tags • Anyone tired of opening 30 listings to find one good deal ────────────── RESPONSIBLE USE ────────────── ⚠…
