Tamper-evident chain

Each entry's hash incorporates the previous, so modifying any record breaks every hash that follows.

Merkle-anchored snapshots

Periodic snapshot roots are published externally. Any inclusion can be proven in O(log n) without re-reading the full log.

Independent verification

Auditors verify proofs using only the public snapshot root — no server access, no trust required.

Pure TypeScript logic

Define steps, guards, and validation as plain TypeScript — no DSL, no framework coupling.

Render anywhere

Works with React, Vue, Angular, Svelte, SolidJS, and React Native using the same engine.

Headless by design

Flow logic is completely decoupled from UI. Swap renderers without touching your business rules.

Zero dependencies

No bloat, no lockfile surprises. Pure TypeScript you can audit in minutes.

Runs anywhere

Evaluate policies in Node, edge runtimes, or the browser — identical behaviour across all targets.

Plain object policies

Authorization rules are ordinary TypeScript objects. No DSL, no magic, no runtime surprises.

Specification Pattern

Compose fine-grained rules into complex conditions using and, or, and not combinators.

Define once, use everywhere

Write a rule once and combine it freely across your entire application without duplication.

Self-explaining outcomes

Rules describe why they passed or failed — useful for debugging and generating user-facing messages.
