# BAML: Basically A Made-up Language

BAML is the programming language for agents.



[Homepage](https://www.boundaryml.com/) | [Explore BAML](https://www.boundaryml.com/explore) | [Discord](https://www.boundaryml.com/discord)

</div>

BAML looks like TypeScript, but every feature is built so agents make fewer mistakes:

- Statically typed like Rust, with colorless concurrency like Go.
- Types persist at runtime. There is no `any`.
- Errors are typed and statically analyzed.
- The filesystem describes the modules/namespaces.
- Run BAML standalone, or call it from any language of your choice (Python, TypeScript, Go, and more).

## Try it out

```bash
brew install boundaryml/tap/baml
baml agent install
baml init
baml ide install --code
```
