appscanner

Find your next apartment in Israel before everyone else does.
Scans Yad2 + Onmap every 15 minutes. Telegrams you the moment a new listing matches your spec — with a one-tap WhatsApp link to the owner and a market-fit score.

Why

The Israeli rental market moves fast. A good listing in a tight neighborhood is gone within hours. Refreshing Yad2 manually doesn't scale and the official saved-search emails are slow and noisy.

appscanner runs the search for you on a 15-minute cadence and only pings when something actually new appears that matches your spec. It also tells you whether the apartment is a deal compared to the local market.

Features

• 📡 Two sources, one feed — Yad2 (via a proxy to bypass anti-bot) and Onmap, deduped to a single stream
• 🎯 Sharp filters — neighborhoods, rooms, price, square meters, floor, amenities, agency/private
• 📍 Smart geo-fallback — when a listing's neighborhood field is empty, coordinates are reverse-geocoded so you don't miss it
• 📊 Market-fit score — ranks every listing 0–100 against your ideal price / size / floor / amenities, with explainable factor breakdown
• 💸 ₪/m² vs city mean — every alert tells you if the listing is cheap (top 25%) or pricey (bottom 25%) for the city
• 🔥 Hot-deal flag — private listings priced ≥10% below city mean get highlighted
• 📲 Telegram alerts — one message per listing with photo, address, owner phone (where available), prefilled WhatsApp link, and source-deep-link
• 👥 Multi-chat fan-out — DM yourself + share a group chat for collaborative hunting
• 🌙 Active hours — pause overnight, scan during the day
• 🗺️ Web dashboard — searches, optimal ranking, map with clustering, activity charts
• 👥 Shared tracker — collaborative tab for 2-3 roommates: shortlist apartments from any source, track status (interested → contacted → visited → signed), assign who's reaching out, leave notes

Quickstart

You need: Node 20+, a free Supabase project, a Telegram bot (@BotFather → /newbot), and optionally a free ScraperAPI key for Yad2.

git clone https://github.com/roeimichael/appscanner.git
cd appscanner
npm install
cp .env.local.example .env.local   # then fill it in

Apply the schema to your Supabase project (paste both files into the SQL editor, in order):

supabase/migrations/0001_init_appscanner_schema.sql
supabase/migrations/0002_tracker.sql

Run it:

npm run dev
# open http://localhost:3000

Open /settings, save your Telegram bot token + chat id, then /searches/new to create your first search.

Self-host on Vercel + Supabase

Free tier on both is plenty.

vercel link
vercel env add SUPABASE_URL              production
vercel env add SUPABASE_SERVICE_ROLE_KEY production
vercel env add SCRAPERAPI_KEY            production   # optional
vercel env add CRON_SECRET               production
vercel env add ROOMMATES                 production   # comma-separated names for tracker tab
vercel deploy --prod

Vercel Hobby cron caps at one fire/day, so the live trigger runs from Supabase:

create extension if not exists pg_cron with schema extensions;
create extension if not exists pg_net  with schema extensions;

select cron.schedule('appscanner-scan-15min', '*/15 * * * *', $cron$
  select net.http_post(
    url := 'https://YOUR-DEPLOYMENT.vercel.app/api/scan',
    headers := jsonb_build_object('Authorization', 'Bearer YOUR_CRON_SECRET'),
    body := '{}'::jsonb
  );
$cron$);

After your first deploy, hit /api/scan?force=1&bootstrap=1 once — it backfills the dedup state silently so you don't get a flood of "new!" pings for every listing already on the market.

Caveats

• Yad2 hides owner phones behind an authenticated reveal — only the source-deep-link gets sent for Yad2 listings. Onmap exposes phones freely.
• ScraperAPI free tier covers ~5000 reqs/month; default cadence + active-hours stays well under that.
• Designed around the Israeli market — Hebrew neighborhood names, ₪ currency, IL phone format.
