iii-hq/iii

iii unifies diverse backend tools like API frameworks, task queues, and schedulers into a single engine with Function, Trigger, and Worker primitives, simplifying distributed backend development.

Core Features

Unified Backend Engine: Consolidates API frameworks, task queues, cron schedulers, pub/sub, state stores, and observability into a single system.

Simplified Primitives: Utilizes Function, Trigger, and Worker to abstract complex distributed backend logic.

Durable & Interoperable Execution: Enables robust, language-agnostic workflow orchestration.

Live System Traits: Offers real-time discovery, extensibility, and comprehensive observability across the entire stack.

Multi-language SDKs: Provides official SDKs for Node.js, Python, and Rust, alongside AI agent integration.

Detailed Introduction

iii (pronounced 'three eye') is a powerful backend orchestration platform designed to simplify the complexities of distributed system development. It replaces the need for multiple disparate tools—such as API frameworks, task queues, and cron schedulers—with a single, unified engine. By introducing three core primitives: Function, Trigger, and Worker, iii provides a cohesive model for execution, enabling durable orchestration, language interoperability, and real-time observability. This approach streamlines configuration, deployment, and monitoring, allowing developers to focus on business logic rather than infrastructure.
