We build the Sailfin programming language — an AI-native, systems-friendly language designed for precision, safety, and introspection.
Sailfin is a pre-1.0 open-source project developed in the open. The self-hosted native compiler, runtime, standard library, documentation, and website all live in a single public monorepo.
