Modeloop is a tool designed to generate code and deploy on embedded systems. The core idea behind this product is to create a vertical solution to design, test and iterate on the model faster, leveraging the modern software practices like Git. For this reason, Modeloop avoids vendor lock-in by saving model data as readable JSON rather than proprietary formats, making model reviews significantly easier.

At its core, Modeloop is conceived with a developer-first mindset, focusing on delivering an optimal user experience. This approach comes from my personal experience working in the robotics and automotive industries where I've experienced firsthand the frustration of fighting with tool configurations. The software we use should be built to accelerate innovation, not spend all day setting the right parameters to make the tool work. This is why it is engineered to prioritize developer happiness by automating the complex under-the-hood operations, resulting in a cleaner UI/UX. There is still a lot to do, though.

Modeloop supports a comprehensive library of standard blocks and also Finite State Machines (FSM) for advanced diagram modeling. Within the engine, a mathematical consistency checker runs automatically, blocking code generation if any defined contracts in the model exhibit mathematical inconsistencies.

Furthermore, Modeloop features an integrated test harness that allows developers to test their models directly within the UI, supporting MIL (Model-in-the-Loop), SIL (Software-in-the-Loop), and PIL (Processor-in-the-Loop) simulations. This built-in Testing & Validation suite accelerates the production of testing and code generation artifacts proving that verifying model logic isn't a separate project, but an intrinsic part of the design process that speeds up the V-model workflow.

As a solo-founder project, I don't yet have all the certifications of the industry giants. There are surely some edge-case code generation bugs I haven't hunted down yet. But the core engine is solid, fast and, honestly, a joy to use. There's a lot left to polish — my roadmap for the coming months is packed with improvements. Maybe too many, haha.

But… yes, the tool is in Beta. And I'd be thrilled to hear your feedback and take your criticism, however brutal it may be — in fact, I invite you to technically tear my design choices apart.

I'll be here in the comments all day to respond, but if you'd rather, you can DM me on Instagram (@_lucamark) or via mail (lucamarkdev@modeloop.app).

Enjoy, Luca Marchionna
