GoAkt is a distributed actor framework for Go, inspired by Erlang and Akka. It enables you to build reactive and distributed systems with typed actor messages. From v4.0.0 onward, any Go type can be used as actor messages—no protocol buffers required. This documentation is designed for both users getting started with the framework and collaborators contributing to the project. It focuses on concepts, architecture, and efficient usage patterns rather than exhaustive code examples.

​
What’s New in v4.0.0

  • Unified APIs: Single actor reference (*PID), single lookup (ActorOf), unified scheduler
  • Type flexibility: any replaces proto.Message across all message-passing surfaces
  • Pluggable serialization: ProtoSerializer (default) and CBORSerializer for arbitrary Go types
  • Simplified remoting: Config-only public API; client is internal
  • Path interface: Location-transparent actor identity replacing *address.Address

​
Requirements

  • Go 1.26 or higher
