iii
iii is an open-source engine for composing, extending, and observing services and AI agents as workers within a unified, interoperable system.
iii is an open-source engine designed to manage software stacks by treating every service and AI agent as a pluggable worker. Instead of building integrations, developers write functions in languages like Python, Rust, or Node and register them directly within the system. The engine provides durable orchestration, allowing these workers to execute across different languages as if they share a single runtime. It includes built-in observability for tracking operations, traces, and system behavior in real-time. By providing a live discovery mechanism, the platform enables adding new capabilities to running systems without redesigning the architecture. It is built for developers who need a unified backend design that agents and humans can reason about.
