Aether: A Compiled Actor-Based Language for High-Performance Concurrency

Hi everyone, This has been a long path. Releasing this makes me both happy and anxious. Today I’m introducing Aether , a compiled programming language built around the actor model and designed for high-performance concurrent systems. Repository https://github.com/nicolasmd87/aether Documentation https://github.com/nicolasmd87/aether/tree/main/docs Aether is open source and available on GitHub. Overview Aether treats concurrency as a core language concern rather than a library feature. The programming model is based on actors and message passing , with isolation enforced at the language level. Developers do not manage threads or locks directly — the runtime handles scheduling, message delivery, and multi-core execution. The compiler targets readable C code , which: Keeps the toolchain portable Allows straightforward interoperability with existing C libraries Makes the generated output fully inspectable Runtime Architecture The runtime is designed with scalability and low contention in m
