## What it is
Vanus is an open-source, cloud-native, serverless message queue with built-in event processing capabilities, written in Go. It connects SaaS applications, cloud services, and databases to build event-driven pipelines and, via Vanus AI, real-time AI applications like chatbots with auto-updated knowledge bases.

## Use cases
- build event-driven applications connecting SaaS and cloud services
- replace Kafka or RabbitMQ with a serverless event bus
- stream events from webhooks and SaaS apps into microservices
- transform and filter events between systems
- sync database changes to a data lake in real time
- build a chatbot with an auto-updated knowledge base from SaaS sources
- route CloudEvents between producers and consumers

## When to choose
- you need an event bridge connecting SaaS tools like Slack, Shopify, or Stripe to your services
- you want a Kubernetes-native, serverless message queue with built-in event transformation
- you need CloudEvents-compatible event streaming with connectors
- you want real-time data pipelines without managing Kafka infrastructure

## When to avoid
- you need a battle-tested, high-throughput message broker with a large community
- you require strict ordering guarantees or Kafka ecosystem tooling
- you want a project with frequent releases and active development
- you need a simple point-to-point queue without event processing
