iii is a Rust-based runtime engine that composes backend services from three primitives (Worker, Trigger, Function), letting polyglot workers connect over WebSocket with zero integration code. It bundles queues, cron, HTTP, state, observability, agents, and sandboxes into one live system surface, installable via SDKs for Python, TypeScript, and Rust.

Use cases

• compose backend services without writing integration code
• run python and typescript workers in one system
• add queues cron and agents as installable workers
• observe all services in real time
• build ai agent systems with shared runtime
• extend a live system with zero downtime

When to choose

• you want to eliminate per-service integration overhead across a polyglot stack
• you need queues, cron, HTTP, state, and agents from a single runtime
• you want services installable like npm packages
• you are building agentic or event-driven backends in Python, TypeScript, or Rust

When to avoid

• you need a battle-tested framework with a long stability record
• you prefer conventional per-service architectures with mature tooling
• your stack is single-language and already well served by existing frameworks
• you require an OSI-approved license for commercial use
