Why AgentForge4j

AgentForge4j is an embeddable Java framework for building agentic workflows on top of large language models. Workflows are declared as data — JSON definitions validated against published schemas — and executed by a runtime that coordinates LLM calls, tool invocations, human input, and file output.

It is a framework, not a product: you embed it in your own application. There is no required hosting, account, or service — providers, tools, and file sinks are pluggable through service-provider interfaces (SPIs), and a Spring Boot starter is available for applications that use Spring.

What it gives you

• Declarative workflows. Steps, behaviours, and transitions described in JSON and validated against the published schemas before they run.
• Pluggable LLM providers. Multiple providers are discovered at runtime through a ServiceLoader SPI; add or swap providers without touching workflow definitions.
• Tools and file output. Workflows can invoke tools and write generated artifacts through configurable sinks.
• Two integration styles. A framework-agnostic bootstrap builder, or a Spring Boot starter with configuration properties.

Where to go next

Pick the path that matches what you are doing:

• Evaluating AgentForge4j — understand what it does and try it.
• Integrating it into an application — install, configure, and wire it in.
• Authoring workflows — write and validate workflow definitions.
