BoxLang is a modern dynamic JVM language built for rapid application development. It's 100% Java-interoperable, compiles to JVM bytecode, and deployable anywhere from OS to AWS Lambda to Spring Boot. In this episode, we sit down with Luis Majano (CEO of Ortus Solutions and creator of BoxLang) and Cristobal Escobar (BoxLang community manager) to dig into the wave of innovation that has hit the platform over the past few months.


We cover the BoxLang AI v3 release, a major overhaul that ships multi-agent orchestration with parent-child hierarchies, an AI Skills system based on Anthropic's open standard, MCP server integration (both consuming and serving), a composable middleware layer with six built-in classes including a FlightRecorder for deterministic CI testing, and a unified API spanning 17 AI providers. Luis and Cristobal walk us through the highlights of a 7-part BoxLang AI deep dive series, covering tools, memory systems & RAG, streaming, middleware, and MCP. We also touch on the BoxLang Spring Boot Starter, BoxLings (an interactive TDD/BDD learning platform), and TestBox 7's real-time streaming test runner.


Whether you're a Java developer curious about dynamic JVM languages, an AI engineer looking for a productive alternative to Python-based agent frameworks, or just want to see what the JVM ecosystem can do in 2026, this episode is for you.
