franz-go is a feature-complete, pure Go Apache Kafka client library supporting Kafka 0.8.0 through 4.2+, including producing, consuming, transactions, and administration. It works with any Kafka-compatible broker such as Redpanda, Confluent Platform, Amazon MSK, and Azure Event Hubs.

Use cases

• produce and consume Kafka messages from a Go application
• build exactly-once transactional event pipelines in Go
• administer Kafka clusters programmatically
• consume Kafka topics with consumer groups and rebalancing
• connect Go services to Redpanda or Amazon MSK
• encode and decode messages with a schema registry client
• stream events with compression and SASL/TLS authentication

When to choose

• you need a pure Go Kafka client with no C dependencies
• you require full Kafka feature coverage including transactions, EOS, and share groups
• you need a high-performance client with low goroutine overhead
• you work with Kafka-compatible brokers like Redpanda or MSK
• you want built-in admin and schema registry support in one ecosystem

When to avoid

• your project is not written in Go
• you need a simple high-level wrapper rather than a full-featured client
• you rely on the next-generation group protocol without opting in explicitly
• you need a client for a non-Kafka message broker
