Build Forms, APIs, and Agentic Workflows with One Self-Hosted Developer Productivity Platform - Form.io

# Form.io Self-hosted middleware infrastructure for forms, APIs, and agentic workflows in regulated industries. Form.io is a self-hosted developer productivity platform that uses JSON schema as a single source of truth for forms, APIs, and agentic workflows. It is middleware infrastructure: every form generates a REST API automatically, configurable server-side Actions handle integrations and authentication, and the Universal Agent Gateway (UAG) extends the same JSON schemas into runtime context, guardrails, and data access for AI agents. Regulated industries — government, financial services, healthcare, insurance — deploy Form.io entirely inside their own IT environment and achieve their own compliance certifications (FedRAMP, HIPAA, etc.) on top of it. ## Essential Reading - [How Form.io Works](https://form.io/how-it-works.md): Architectural overview — JSON schema as a single source of truth, auto-generated REST APIs per form and resource, server-side Actions as configurable middleware, and forms embedded directly into your application. - [Universal Agent Gateway (UAG)](https://form.io/uag.md): Open-source, MIT-licensed MCP server. Turns the JSON schemas you already use for forms, APIs, and workflows into dynamic context, guardrails, and authenticated data access for AI agents — without retraining models or ripping out your stack. - [Enterprise Self-Hosting](https://form.io/enterprise-self-hosting.md): Form.io deployed entirely inside the customer's IT environment. Customers achieve their own FedRAMP, HIPAA, and other compliance certifications on top of the platform. - [Form.io Features](https://form.io/features.md): Full feature catalog — auth, RBAC, server-side Actions, integrations, PDF workflows, mobile, accessibility, audit, white-label, and multi-tenancy. ## Build with Form.io - [Form.io on GitHub](https://github.com/formio): Open source core, SDKs, and UAG.
