The Problem We Set Out to Solve

The AI agent landscape in 2025 was dominated by Python frameworks — LangChain, CrewAI, AutoGen. They worked well for prototyping, but when enterprises needed production-grade agent orchestration with governance, multi-tenancy, and budget controls, the options were thin.

Java powers most enterprise backends. Spring Boot is the de-facto standard. Yet there was no serious multi-agent orchestration framework for the JVM ecosystem. We decided to change that.

Why Java and Spring Boot?

This was our most debated engineering decision. Here's what tipped the scales:

  • Type safety at scale — When you're orchestrating dozens of agents with complex workflows, runtime type errors are catastrophic. Java's type system catches entire categories of bugs at compile time.
  • Spring ecosystem — Dependency injection, configuration management, actuator health checks, Micrometer metrics — all production essentials that come free with Spring Boot.
  • Spring AI integration — The Spring AI project gave us a clean abstraction over LLM providers (OpenAI, Anthropic, Ollama) without vendor lock-in.
  • Enterprise adoption — Our target users already run Java in production. No new runtime to deploy, no new language to learn.

The 7 Process Types

We didn't start with 7. We started with Sequential and iterated based on real-world workflow requirements:

Sequential

The simplest pattern. Tasks run in dependency order, each receiving prior outputs as context. Perfect for linear pipelines like extract → transform → load.

Parallel

Independent tasks run concurrently with automatic synchronization barriers. We use Java's virtual threads (Project Loom) for efficient concurrency without thread pool tuning.

Hierarchical

A manager agent creates execution plans, delegates to specialist workers, and synthesizes results. This mirrors how human teams operate — a tech lead breaking down a feature into tasks.

Iterative

Execute-review-refine loops that repeat until a reviewer agent approves the output or max iterations are reached. Essential for content generation, code review, and quality assurance workflows.

Self-Improving

Extends the iterative process with dynamic skill generation. When the reviewer flags a capability gap (something no existing tool can do), the framework generates a new skill, validates it in a sandbox, registers it in the skill registry, and re-executes.

Swarm

Distributed fan-out with parallel agents per target. Think of a security audit that spawns one agent per service in your microservices architecture, each working independently.

Composite

Chain any of the above into a pipeline: Parallel → Hierarchical → Iterative. This is the meta-process that makes complex enterprise workflows possible without custom code.

Enterprise Features That Matter

Building for enterprises means more than just features — it means trust boundaries:

  • Governance Gates — Human-in-the-loop approval checkpoints that pause workflows before sensitive operations. No agent runs unchecked.
  • Budget Tracking — Real-time token and cost tracking with HARD_STOP or WARN enforcement. No surprise bills.
  • Multi-Tenancy — Tenant-isolated memory, knowledge, quotas, and budgets. One deployment serves many teams safely.
  • RBAC — Tool permissions (READ_ONLY, WORKSPACE_WRITE, DANGEROUS) ensure agents can only access what they're authorized to use.

What's Next

We're actively working on:

  1. Visual workflow builder — A drag-and-drop UI for composing agent workflows
  2. Marketplace — A community-driven skill marketplace where teams can share and discover agent capabilities
  3. Distributed execution — Running swarm processes across multiple nodes for massive-scale orchestration

If you're building AI-powered workflows in Java, we'd love your feedback. Check out the framework on GitHub and join the conversation.
