We’re already building what comes after Langium — and it’s not just the next release.
After years with Xtext and Langium, we’ve hit clear performance limits at scale. This article explains where they come from, and ends with a glimpse at what we’re working on next.

The monaco-languageclient project is an Open Source Software success story and many thanks go to my co-maintainer github.com/CGNonofr
Finally, monaco-languageclient version 10 (www.npmjs.com/package/mona...) is available.
You now have all tools at hand to create editor-centric web applications utilizing one or many language clients to connect to language servers via the language server protocol with one package.
Langium 4.0 is out! 🚀
Highlights:
- Infix operator rules for clearer operator precedence
- Strict mode enforcing explicit types for more stable DSLs
- Multi‑target references for flexible cross‑links

Over the past year, I’ve had a bunch of great conversations about LLMs and DSLs. It’s clear we’re onto something big—this combo really shines when it comes to making AI work in specific domains.
We finally wrote it up. Curious what you think!
We're pioneering semiformal AI communication through domain-specific languages—solving the precision and reliability challenges that natural language prompts struggle with. Our latest article details how language engineering transforms AI interaction. 🦊

How does Langium have only 790 stars? The project is amazing.
It lets you define a parser for a new language, with syntax checking diagnostics (intellisense UI) built into your IDE, and APIs for your own diagnostics (f.e. your own type checking).
Absolutely phenomenal.

How does Langium's Typir library have only 27 stars!? This has to be one of the most interesting advancement in language engineering!
It's a library for common patterns for defining the type checking mechanics of your own programming language, with IDE diagnostics.
