OrdoOpen-Source Decision Platform

Author, test, and govern business rules — with Studio, platform governance, and a fast engine under the hood.

🏛️

Decision Platform

Org & project management, fact catalog, typed decision contracts, and full version history. Own your decision logic — don't scatter it across codebases and spreadsheets.

🎨

Studio

Drag-and-drop flow editor, decision tables, one-click template instantiation, and test case management. Author rules without friction.

🧪

Test Management

Create, run, and export test suites per ruleset. CI-compatible YAML. Know your rules work before they ship.

⚡

Fast Engine

Sub-microsecond execution with Cranelift JIT. Runs as HTTP · gRPC · WASM · CLI or embedded in any Rust application.

🛡️

Governance

Typed input/output contracts, audit logging, Ed25519 rule signing, and rollback. Traceable and compliant by default.

🔌

Runs Everywhere

Single binary server, browser via WebAssembly, embedded in Rust apps. One engine across every deployment target.
