## Overview
### One Engine.trigger any language
The centralized orchestration runtime for distributed polyglot function execution.
React simplified frontend with Component and Context. iii does the same for backend.
- Polyglot execution — any language participates through one universal protocol.
- Complete observability — logs and traces auto-injected into every invocation.
- Self-hosting/BYOC — connect existing domains and services, full portability.
- Shared capabilities — State, Streaming, Observability accessible to every function.

## Architecture
### One engine.Three primitives.
iii unifies your entire backend with Function, Trigger, and Worker. One mental model for every backend system.
Anything that does work.
A Function receives input and optionally returns output. It can live anywhere — locally, on cloud, on serverless, or as a third-party HTTP endpoint. All Functions are treated the same within iii.
#### The Engine does it all
Operations flow through the Engine to any worker, in any language

## Polyglot Runtime
### One protocol. Any language.
Python registers a function. Rust registers a function. Node.js consumes both.Simply register functions and trigger them.

## Observability
### Trace-level visibility. Built in.
Every function call, every span, every metric — captured automatically with OpenTelemetry. Export to any backend or use the built-in console.
#### Built-in Console
Native trace viewer with waterfall, flame graph, service breakdown, and trace map visualizations.
#### Export Anywhere
OTLP-native export to any OpenTelemetry-compatible backend — Datadog, Grafana, Honeycomb, and more.
#### Zero-Config Tracing
Auto-instrumentation for all function calls with W3C traceparent propagation across language boundaries.
