Compozy

Compozy runs multi-agent AI systems from YAML workflows. It is an open source workflow orchestration platform for individuals and teams building AI applications, and the free tier is the full engine rather than a trimmed demo.

You get the complete workflow engine, every task type (basic, parallel, collection and router), AI agent management, and custom tools written in JS or TS on the Bun runtime.

MCP server integration is included, and you host it yourself, with community support as the help channel.

Two paid levels sit above that.

A managed Cloud plan is marked as coming soon and adds managed infrastructure, automatic scaling, monitoring and observability, priority support, a 99.9% uptime SLA and team collaboration features.

An Enterprise plan with custom pricing adds on-premise deployment, advanced security and compliance, custom integrations, a dedicated support team, training and onboarding.

If you want to define agent pipelines in config files and keep everything on your own servers, Compozy covers that today at no cost.

Cloud is the part you will have to wait for.
