# Introduction

The **Go** SDK is the framework-agnostic **core**: a wire-envelope codec,
contracts and dead-letter helpers that read and write the exact same strict JSON
envelope as every other language in the ecosystem.

At its heart it is the **codec**: you build (or decode) the canonical envelope and
move the bytes with your own broker client, so it works over any broker. On top of
that — and **still zero-dependency** — an optional `App` runtime
(publish/consume/worker loop) and **transport modules for all seven brokers** are
available when you want them.

## What you get

- Canonical, schema-validated JSON envelopes (`schema_version: 1`) — no language
  lock-in.
- A built-in `trace_id` on every message for cross-service correlation.
- URN routing (`urn:babel:<context>:<event>`) on a stable key.
- **Zero dependencies** in the core (standard library only) — bring your own broker
  client.
- An **optional `App` runtime + transport modules** for Redis, RabbitMQ, Amazon SQS,
  Azure Service Bus, Apache Pulsar, Apache Kafka and Apache ActiveMQ/Artemis — opt in
  when you want publish/consume instead of just the codec. See
  [Runtime & transports](/docs/babelqueue-go/1.x/runtime-and-transports/).
- **Framework adapters** — `…/asynq` and `…/machinery` bind the codec to those Go
  task queues.
