Kameo is a Rust library for building fault-tolerant, asynchronous actor-based systems on top of Tokio. It supports local and distributed messaging via libp2p, supervision strategies for failure recovery, and type-safe message handling.

Use cases

• build concurrent Rust applications with an actor model
• implement fault-tolerant microservices with supervision and restarts
• communicate between actors across network nodes without schemas
• manage backpressure with bounded and unbounded mailboxes
• monitor a running actor system's supervision tree and throughput
• replace gRPC with dynamic schema-free remote messaging

When to choose

• you want Erlang-style actors with async Rust and Tokio
• you need lightweight local concurrency plus optional distributed actors
• you prefer compile-time type-safe messages over schema-based RPC

When to avoid

• you need a battle-tested actor framework with a large ecosystem
• your project requires predefined schemas and gRPC interoperability
• you are not using an async runtime compatible with Tokio
