framework — Overview

A platform-agnostic PHP framework for building business domains that do not depend on their host. Write controllers, forms, queries and services against contracts, then run the same code standalone, inside a Moodle plugin, or inside a WordPress plugin, by swapping a thin adapter.

Your domain should not know, or care, where it runs.

See Architecture for the four pillars, the OSS × proprietary boundary, the concern-first 3-tier layout, the bridge contracts, and the Active-Record / Eloquent compatibility matrix. See Bootstrap for the boot phases, what the kernel provides at boot, and the bridge contracts an adapter implements.

Open source and MIDDAG

The framework, the Moodle and WordPress adapters, and middag-io/ui are open source under Apache-2.0 — the generic plumbing, free, forever. The governed domain infrastructure that is genuinely hard to get right — reliable event delivery, async jobs with retry and audit, an EAV query engine, multi-tenancy, and licensing — is MIDDAG's proprietary product, built on top of this OSS and opt-in. The framework never imports the proprietary layer; the dependency only ever points downward.

Licensing note

Apache-2.0. On the 1.x line the API is still consolidating: a minor release may carry a documented breaking change — see API-STABILITY.md.
