The Timeseries Refinery is an open-source platform for storing, computing and visualising versioned time series data — built for data-driven teams in energy, trading and industry. Its bitemporal storage keeps every version of every series: any series can be queried as it was known at any past date (as-of queries) — and computed series follow the same law: formulas evaluate against the versions known at that date. It provides a traceable formula engine, real-time dashboarding, an Excel client, and full Python and REST APIs. Learn more
