## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: concurrency, rpc, middleware
- domain: microservices, developer-tools, backend
- platform: rust, cross-platform
- tags: actor-model, tokio, fault-tolerance, supervision, libp2p, message-passing, distributed-actors
