Transpile-first
No proprietary runtime. Emit validators and functions for modern and legacy platforms from one source file.
Write rules once.
Run them everywhere.
OrbaLang is a transpilation-first business-logic language for the
Post-Project World — auditable when / then policies
that emit Python, TypeScript, Java, COBOL, and more. Created by
Luigi Pascal as part of the OrbaOS™ framework.
Why OrbaLang
Governed rules
Top-level rule programs with audit: metadata — built for auditors and operators, not just developers.
Reverse lift
Import Semantic IR JSON or emitted python-rule back into .orba for adoption and round-trip checks.
OrbaOS galaxy
Programme surfaces on orbaos.com, *.orbaos.com, and affiliated domains such as
languagefoundry.io. OrbaLang is at lang.orbaos.com; the playground at /playground/.

Not another rules engine
| OrbaLang | Typical rules engine | |
|---|---|---|
| Runtime | None — transpile to your stack | Central server / RETE |
| Syntax | Minimal, audit-readable | XML, DSL, or UI-only |
| Legacy | COBOL, RPG, ABAP, SAS emit · see also Language Foundry | Often modern-only |
| Doctrine fit | Flow-layer rules for OrbaOS™ | Product-specific |
