Boundary

Boundary develops BAML (Basically A Made-up Language), an open-source, Apache-2 licensed programming language designed for AI agents and developers building with models. BAML pairs a TypeScript-like syntax with a strict type system that has no escape hatches, along with built-in tracing and profiling of every function. It can run standalone or be integrated into existing projects in languages including Python, TypeScript, Java, C#, Go, Rust, and others. The company also plans a paid offering, Boundary Web Services, around observability.
