Iron Babel

IronBabel is a protocol bridge, not just an API gateway. It connects HTTP APIs to gRPC, GraphQL, WebSockets, MQTT, AMQP/RabbitMQ, and ZeroMQ in one lightweight runtime.

Features

• Protocol translation between:
  • REST/HTTP ↔ GraphQL
  • REST/HTTP ↔ gRPC
  • HTTP ↔ AMQP publish/consumer webhook flows
  • WebSockets ↔ HTTP/SSE
  • WebSockets ↔ REST polling
  • HTTP ↔ MQTT publish/webhook flows
• Automatic schema discovery and generation
• Request/response transformation
• Developer-friendly configuration
• Comprehensive monitoring and metrics via built-in admin dashboard
• Advanced features like rate limiting and circuit breaking

Monitoring Dashboard

The built-in admin dashboard is available at http://<host>:<port>/admin/ and provides real-time request metrics, latency percentiles, error rates, per-route stats, and a draft configuration editor with transport templates for common route and listener setups.

Project Structure

The project is organized into several key components:

• config/: Configuration management
