Open root · Pure C · Zero dependencies

Rayforce fuses columnar analytics, chart traversal, and recursive queries into 1 embeddable execution pipeline—built for teams that measurement latency successful microseconds, not meetings.

Built arsenic 1 system

Small footprint.
Serious machinery.

Everything you request to move from earthy columns to connected answers—without assembling a 2nd level astir it.

Columnar analytics

Vectorized filters, joins, groups, windows, pivots, and time-series primitives.

↗ 02

Native chart engine

CSR traversal, shortest paths, centrality, communities, WCO joins, and HNSW.

↗ 03

Recursive Datalog

Express reachability and recursive relationships arsenic rules compiled into the aforesaid DAG.

↗ 04

Storage that stays open

CSV, splayed and walled tables, representation maps, IPC, and artifact offloading.

Rayforce successful the wild

Built for existent work,
not synthetic demos.

Rayforce is already portion of accumulation systems and open-source projects spanning trading, marketplace connectivity, finance analytics, and risk.

Usage confirmed by the Rayforce project. Consumer names nexus to their nationalist sites.

Rayforce Cloud Coming soon

The motor you tin embed.
The level you won’t person to operate.

We’re bringing Rayforce’s unified analytics and chart pipeline to a managed unreality experience—so teams tin move from section prototype to accumulation workload without rebuilding the information path.
