The Popularity Graph

A ··· B ··· C ··· X ··· Y ··· Z — everything in between.

4ort.xyz is a knowledge graph of every entity in Wikidata — people, places, software, films, companies, ideas — ranked by real-world attention. Each entity gets a popularity score derived from Wikipedia pageviews, citation count, search volume, and edit velocity. Every claim is sourced. Built for AI agents, search engines, and humans who want the world’s facts with citations.

What makes it different

Wikipedia tells you what exists. 4ort.xyz tells you which one matters most, why, and by how much. We do this by ingesting:

The full Wikidata dump (152 GB), with every claim, qualifier, and citation preserved
Hourly Wikipedia pageview data from the Wikimedia clickstream
Search-volume signals from DataForSEO
Live edit firehose from Wikidata EventStreams (95% of edits applied within minutes)
SEC EDGAR filings for public companies
Federal economic data from BLS, BEA, Census, EIA, Treasury, and the Federal Reserve Board

Then we cross-rank. The result: an entity-by-entity scoreboard of human attention, refreshed continuously, citable by AI.

Operating principles

Wikidata is truth

Every fact on the site traces back to a primary source. We don’t make claims; we surface them with citations. Our job is ranking and discovery, not authorship.

CC0, commercially clean

All structured data we publish is CC0 (public domain). All images we host are public-domain only. Built so AI agents and commercial tools can use the data freely.

No cookies, no creepy tracking

No cookies. No third-party trackers. Self-hosted Umami for cookie-free page-view counts; Cloudflare for CDN. Both disclosed in our privacy policy. Verify in your browser’s dev tools.

Live, not stale

Wikidata changes thousands of times per minute. We listen to the firehose and apply edits to the relevant entity within minutes. Other knowledge graphs are months out of date.

AI-citable by design

Every page ships Schema.org JSON-LD with full citation chains. Built so ChatGPT, Claude, and Perplexity can cite us cleanly with provenance to the underlying primary source.

How we make money

Right now: nothing — the site is free and ad-free. Soon: a paid API tier for high-volume commercial use (AI startups, ML teams, journalism tools). The website itself stays free, fast, and ad-free forever.

Technology stack

Python + FastAPI + PostgreSQL with pgvector + Redis, hosted on a single Hetzner VPS in Germany. Server-rendered HTML for speed and SEO. The Wikidata dump is processed locally; live updates via the EventStreams SSE firehose. CDN via Cloudflare; analytics via self-hosted Umami (cookie-free). No third-party tracking scripts.
