Open Integration Hub
What Open Integration Hub is
Open Integration Hub is a free, open-source framework for synchronizing data between business applications. Its hub model lets each application connect through one connector to the framework, rather than requiring separate connections between every pair of applications. Components cover authorization, validation, routing, central data storage, standard data models, metadata storage, and connectors. Connectors can translate formats such as XML or CSV into JSON, define integration actions and triggers, and use transformers to map schemas to standard models; the project suggests JSONata for this work. Connectors can be built for any solution, published as open source, and distributed as Docker containers. The platform describes an embeddable integration catalog, an API for custom implementations, backend flow management, and flow templates. It supports API, self-hosted, and web use. Basaas and elastic.io are identified as platforms built on or implementing the framework. Components use the Apache 2.0 license, which permits commercial use.
Who it suits
It suits software vendors, platform providers, system integrators, and internal IT departments building application integrations. The framework also supports teams that need custom connectors or managed integration flows.
What it does well
- Free plan available
- One connector per application in hub model
- Supports API, self-hosted, and web
- Connectors can ship as Docker containers
- Apache 2.0 license permits commercial use
What to know first
- Main scenario limits custom fields and components
- Alternative scenario requires manual data mapping
- Pages specify no security certifications
- Paid memberships have annual fees

Verdict
Open Integration Hub provides a standards-focused way to connect business applications through shared models and reusable connectors. Choose it when open-source deployment, custom connectors, or embeddable integration tooling matter more than avoiding configuration work.
