A layered, brick-based architecture.
Quatrain Core stacks reusable bricks from runtime to experience. Each layer is independently usable and replaceable.
No-code studio, AI agent, dashboards.
State machines, lifecycle, MDM.
Typed business objects and rules.
Auth, data, storage, notifications.
Infra-agnostic deploy targets, driven by Tycho.
Four commitments.
Infrastructure agnostic
Run the same logic on any cloud or on-prem.
Stateful by design
State machines are first-class primitives; BPM is on the roadmap.
Dual access
Every brick reachable in code and no-code.
Open source
AGPL-v3-only, monorepo-first.
What's cooking.
The ecosystem keeps growing — its major tracks are actively evolving.
BPM Engine
A full Business Process Management engine with visual state machines, built on the existing state-machine brick.
Tycho
Infrastructure, deployment, cybersecurity and compliance gathered under the Tycho brand and its CLI.
