Prelude Documentation

Prelude v1.0 · Overview

What Prelude is

Prelude is a deterministic pre-decision guard that evaluates system state before irreversible actions execute.

It produces a single answer — Allow or Block — stores that decision, and returns immediately.

What Prelude is not

Deterministic scope

Given the same input, ruleset, and timestamp, Prelude returns the same verdict. This makes audits and incident reconstruction straightforward.

Deployment model

Prelude runs as a self-hosted Fastify + PostgreSQL service. Docker + docker-compose are provided for reproducible deployment.

Pricing & Access

Prelude is offered on a case-by-case basis.

There is no public pricing or self-service onboarding.
