🌀 BabelQueue

Polyglot Queues, Simplified.

One strict JSON message envelope that Laravel, Symfony, Go, Python, Java, .NET and Node.js all speak — over the broker you already run.

---

The problem

Frameworks like Laravel serialize queued jobs with PHP's serialize() — a PHP-only object graph. The moment a Go, Python or Java service needs to consume that job, it can't read it. The usual escapes — adopt Kafka/gRPC, or hand-roll bridge services — are heavy and invasive.

The idea

Don't change your broker. Change only the serialization.

BabelQueue replaces serialize() with a frozen, language-neutral JSON envelope and routes by a URN instead of a class name — so a job produced in one language is consumed natively in another, with a built-in trace_id for end-to-end tracing. No sidecar, no proxy, no broker plugin.

{
  "job": "urn:babel:orders:created",
  "trace_id": "7b3f9c2a-e41d-4f88-9b2a-1c0d5e6f7a8b",
  "data": { "order_id": 1042, "amount": 99.90 },
  "meta": { "id": "…", "queue": "orders", "lang": "php", "schema_version": 1, "created_at": 1749132727000 },
  "attempts": 0
}

A quick taste — Laravel produces, anything consumes

use BabelQueue\Facades\BabelQueue;

BabelQueue::publish('urn:babel:orders:created', ['order_id' => 1042]);

# a Python service consumes the very same message — natively
@bq.handler("urn:babel:orders:created")
def on_order_created(data, meta):
    ...  # AI/ML, data processing, anything

Why teams use it

• 🧩 Agnostic serialization — a strict JSON envelope, no serialize() lock-in.
• 🔖 URN routing — identity (urn:babel:<context>:<event>) decoupled from class names.
• 🔭 Built-in trace_id — follow one message across every service and language.
• 🔌 Broker-agnostic — Redis, RabbitMQ, Amazon SQS, Azure Service Bus, Apache Pulsar, Apache Kafka & ActiveMQ/Artemis — swap by a config line.
• 🪶 Drop-in & lightweight — reuse your framework's worker; zero heavy dependencies.

Ecosystem

Each language ships a framework-agnostic core plus thin framework adapters, so the wire format stays identical everywhere.

Language	Core	Framework adapters + broker transports	Registry	Status
PHP	babelqueue/php-sdk	babelqueue/laravel, babelqueue/symfony (Redis/AMQP/SQS/Pulsar/Kafka/Artemis transports in the core)	Packagist	✅ 1.x
Python	babelqueue	[celery] [django] + broker extras [redis] [amqp] [sqs] [pulsar] [kafka] [azureservicebus] [artemis]	PyPI	✅ 1.x
Go	babelqueue-go	…/redis …/amqp …/sqs …/pulsar …/kafka …/artemis …/azureservicebus + …/asynq …/machinery	Go modules	✅ 1.x
Node.js	@babelqueue/core	@babelqueue/bullmq @babelqueue/nestjs + redis rabbitmq sqs pulsar kafka artemis azure-service-bus packages	npm	✅ 1.x
Java	com.babelqueue:babelqueue-core	…:babelqueue-spring + -redis -sqs -pulsar -kafka -artemis -azureservicebus	Maven Central	✅ 1.x
.NET	BabelQueue.Core	BabelQueue.MassTransit + .Redis .Sqs .Pulsar .Kafka .Artemis .AzureServiceBus	NuGet	✅ 1.x

Brokers — every SDK speaks the same envelope over each: Redis · RabbitMQ · Amazon SQS · Azure Service Bus · Apache Pulsar · Apache Kafka · ActiveMQ/Artemis. Each is locked by the cross-SDK conformance suite and proven by a live cross-language interop demo. (PHP × Azure Service Bus is the one documented deferral — every other (language × broker) cell ships.)

Status: BabelQueue is GA (1.x) — every SDK is published with a SemVer-stable public API (breaking changes require a MAJOR, per the deprecation policy), and each produces and consumes the envelope across the seven brokers above. The wire contract is frozen at schema_version: 1.
