CalcFi Open Data (Cloudflare Pages mirror)

34 free, CC BY 4.0 financial and macroeconomic time series mirrored from primary sources. Cloudflare Pages mirror — global edge CDN, sub-50ms latency from 300+ Cloudflare PoPs worldwide. Identical to the canonical GitLab Pages site.

What this is

This is the Cloudflare Pages mirror of CalcFi Open Data, served from Cloudflare's global edge network (300+ PoPs in 100+ countries). Same content as the canonical GitLab Pages site, but with edge-cached static delivery for faster page loads worldwide. The canonical URL points at the GitLab Pages site.

The dataset covers 34 series across nine categories — mortgage rates, Treasury yields, Federal Funds, CPI, PCE, hourly earnings, unemployment, oil, gas, FX, GDP, deposit rates, and more. Every series is cited verbatim to the underlying primary source (FRED, BLS, Freddie Mac, US Treasury, BEA, World Bank, Federal Reserve, FDIC, EIA). No smoothing, no imputation, no proprietary adjustments. 117,956 observations total.

Built as the data layer behind the free personal-finance calculators at calcfi.app (300+ tools, all cited to primary sources). Released as open data because the underlying primary sources are already public — wrapping them in a CC BY 4.0 license with a permanent DOI just makes them easier to cite and harder to break.
