About F1RE

F1RE is a software engineering company specializing in Model-Driven Engineering, Domain-Specific Languages and Language Engineering. Our engineers work with JetBrains MPS, LionWeb, Xtext, EMF, Rascal and SysML v2.

f1re.io is our technical blog: implementation notes, design decisions and problem reports, written by the engineers doing the work. Our company site is f1re.nl.

What we work on

Interoperability through LionWeb. Models locked into a single tool or a single team get duplicated, and integrating them stays a manual job. LionWeb — an open interchange protocol we co-develop — lets models move between tools, teams and platforms. We advise on LionWeb infrastructure, adapt existing toolchains to open modeling standards, and design workflows that still hold when the number of tools and users grows.

Governed AI. AI that drafts is useful; AI you cannot check is a liability. We formalize domain rules as models, then use those models and their validators to constrain, verify and explain what generated output actually does. The model drafts, the language checks.

Ecosystem. No single vendor or team solves these problems alone. We work in the open model-driven and open-source community, contribute to the tools we depend on, and bring in people from that network when a problem crosses boundaries.

How we work

We work alongside your team rather than replacing it: coaching, architecture review, implementation support and collaborative design sessions. Engagements typically start from a proof of concept, or from an existing system that has become hard to change. The artifacts we build — languages, generators, models — stay with the client.
