Vantage v3 — Institutional Intelligence Platform
Open-Source SEC 13F Hedge Fund Analytics
Vantage v3 is a fully open-source SEC institutional holdings intelligence platform — free for everyone, forever, with no paywalls, no accounts, and no API keys required. It tracks the complete filing history of 42 top hedge fund managers (Berkshire Hathaway, Bridgewater, Soros Fund Management, Renaissance Technologies, Tiger Global, Druckenmiller, Pershing Square, and more) with a minimum of 10 years (40 quarters) of historical data per manager, sourced exclusively from SEC EDGAR 13F-HR XML filings.
The architecture operates in three modes to serve different consumer profiles. Local mode runs a FastAPI + Next.js stack that auto-downloads the 594MB SQLite database from Hugging Face on first start. Direct HF API mode serves pre-generated static JSON responses from Hugging Face's CDN — no authentication, no rate limits, globally distributed. GitHub Pages mode delivers a fully static Next.js export built and deployed automatically by a weekly GitHub Actions pipeline: crawl SEC → parse XML → generate JSON → upload to HuggingFace → deploy GitHub Pages.
The frontend built with Next.js 14 and Recharts delivers quarter-over-quarter position comparison (showing NEW, EXITED, INCREASED, DECREASED positions between any two filing periods), historical portfolio evolution stacked area charts for Top 30 holdings, stock holder intelligence (find every institution currently holding a given stock), and full-text search by manager name, CIK, stock name, or CUSIP. The project demonstrates zero-cost open-source infrastructure: enterprise-quality data with no ongoing hosting expenses.
