Should you build your own One Place?
AI-powered European real-estate search, boards, lead pipeline, and agentic deal discovery
You can build a scheduled personal property monitor, but not One Place: the value is the maintained real-estate corpus, crawler fleet, AI extraction, deduplication, image/semantic search, geo enrichment, and constant source upkeep across millions of listings.

Build me a scheduled personal property monitoring agent, the honest consolation
build for One Place: it watches the sources I configure, it does not rebuild a
live nationwide real-estate index. Requirements:
- Node + Express + better-sqlite3 on localhost:4920, with a small web UI for saved
searches, matches, and lead notes.
- Saved searches live in SQLite: name, source URLs, natural-language criteria, hard
filters, cadence, email recipients, and last-run time.
- A node-cron runner wakes on each cadence, fetches configured source/search pages with
Playwright, and stores raw HTML snapshots for debugging.
- Send cleaned listing HTML to an LLM API key from .env and extract strict JSON: title,
price, currency, surface, rooms, location text, description, image URLs, source URL, and
confidence.
- Match each extracted listing against the saved search criteria with deterministic
filters first, then an LLM yes/no explanation for fuzzy preferences like renovation
potential or sea view.
- Store listings and match decisions in SQLite, dedupe by canonical URL first and fuzzy
title+price+surface+location second; keep price-change history.
- Email new matches via Resend or SMTP creds in .env, including the match reason, key
fields, source link, and unsubscribe/disable link for that saved search.
- Include an MCP server exposing tools: list_saved_searches, run_search_now,
get_recent_matches, explain_match, update_search, and add_lead_note, so Claude/Codex can
operate it from chat.
- No accounts, no telemetry, binds to localhost only. Out of scope: nationwide coverage,
anti-bot arms races, paid data resale, mobile apps, and collaborative CRM.
- README: crawler ethics, robots/terms warning, required API/email keys, how to run the
scheduler, and how to connect the MCP server.The prompt opens pre-filled in your agent. Review it before running.
What would building your own look like?
Run saved searches on a schedule, crawl configured source pages, use an LLM API key to extract listing fields, dedupe into SQLite, email matching finds, and expose an MCP server for chat/coding agents.
What you will need
- cron-style scheduled search runner
- Playwright scraping
- LLM API key for listing extraction
- SMTP or Resend email alerts
- MCP server for agent access
They pay because property search is a moving data pipeline: portals block scrapers, listing HTML changes, duplicates multiply, and the useful part is having the whole market normalized and searchable before a deal disappears.
xmillions of already-normalized listings
xmaintained crawlers across real-estate portals
xAI extraction, deduplication, and image/semantic search at scale
xgeo/POI enrichment and currency/unit normalization
xhosted boards, lead pipeline, sharing, and agentic search
Nothing worth pointing at. That’s why the prompt exists.

Is it cheaper to build or buy One Place?
Adjust the numbers: hours to build, your hourly rate, running costs and the subscription price.
Over 24 months, subscribing is cheaper.
Starting hours estimated from the analysis (multi-week). Does not price what you give up (support, integrations, security).
Is One Place free?
The free plan gives unlimited search and saved searches, capped at 5 boards. The paid plan is Pro at $45.06/mo (checked 08/11/2026).
Can I rebuild One Place?
Not really. One Place’s value is not the code: The market-wide index is the product. See the honest breakdown above.
How much does One Place cost?
One Place costs about $45.06/mo (Pro, checked 08/11/2026), which is $541 per year.
What do I lose by replacing One Place?
Honestly: millions of already-normalized listings; maintained crawlers across real-estate portals; AI extraction, deduplication, and image/semantic search at scale; geo/POI enrichment and currency/unit normalization; hosted boards, lead pipeline, sharing, and agentic search. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to One Place?
No mature open-source alternative worth pointing at, which is exactly why the one-shot prompt on this page exists.
