Ballerina is an open-source programming language for the cloud that makes it easier to use, combine, and create network services. Network primitives in the language make it simpler to write services and run them in the cloud. Structural types with support for openness are used both for static typing within a program and for describing service interfaces. Type-safe, declarative processing of JSON, XML, and tabular data with language-integrated queries. Explicit error handling, static types, and concurrency safety, combined with a familiar, readable syntax make programs reliable and maintainable. Easy and efficient concurrency with sequence diagrams and language-managed threads without the complexity of asynchronous functions. Programs have both a textual syntax and an equivalent graphical form based on sequence diagrams.

TypeSpec is a language for defining cloud service APIs and shapes. TypeSpec is a highly extensible language with primitives that can describe API shapes common among REST, OpenAPI, gRPC, and other protocols. TypeSpec is excellent for generating many different API description formats, client and service codes, documentation, and many other assets. All this while keeping your TypeSpec definition as a single source of truth. Using TypeSpec, you can create reusable patterns for all aspects of an API and package those reusable patterns into libraries. These patterns establish "guardrails" for API designers and make it easier to follow best practices than to deviate from them. TypeSpec also has a rich linter framework with the ability to flag anti-patterns as well as an emitter framework that lets you control the output to ensure it follows the patterns you want.

Xtraitj is a programming language for pure trait-based programming. It is completely compatible and interoperable with the JAVA platform without reducing the flexibility of traits. Xtraitj is integrated in Eclipse (editor with all the standard tooling) and JDT. It is implemented in Xtext, relying also on Xbase.

cowbel is a minimalist experimental programming language. It features strict types, static compilation into real machine code (via C), an object oriented system based on interfaces and composition, generics, no null, and a global garbage collector. It is intended to produce fast, tight code for use in systems programming, and to show that you don't need a complex language to be expressive and usable. We've moved!
