Please don't change my mouse cursor. It is unexpected; disorienting; it is unnecessary; there were probably more pressing areas to focus attention; if the project is successful at some point, you will wind up having to work on it again; and until then you will spend mental energy responding to or ignoring complaints about it.
Hi brudgers, thanks for the feedback. I had the same concern, so I will change it in the next few hours. Do you want to share other feedbacks about the product itself?
Hey, Embedded Dev here, i will suggest my team to use and i will test it out as well. but honestly i feel more than embedded developers it will be more useful for solution engineers who work with direct customers. Regardless i will my feedback here after testing it.
Mostly unrelated, but what is going on with the "I specifically approve section ... of the terms and conditions" when you sign in without an account. Is this a new requirement somewhere?
Other than that, seems interesting! Simulink could always do with a competitor, although I'm always saying Simulink needs a text-based interface. Same signal flow programming model that supports scopes and continues time integrators, just with text instead of drag-and-drop.
I wish that people would not use AI to generate copy or websites, at this point it induces an almost instinctual negative reaction: 'What Modelloop does -- in three movements' is a classical example of AI lingo. I don't have proof but I feel that the most recent models have gotten worse. The rhetorical devices they use are tiring and off-putting at this point.
Hi Developers,
I'm Luca, the creator of Modeloop. I've spent the last 18 months building, from scratch, a model-based design tool and today I'm finally opening the Open Beta.
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 libraries or 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
P.s.: For the HN community, I've prepared a promo code to unlock functionalities through the Pro Plan. Once registered, please insert the promo code HN_PRO_2026 .
can you explain what or how you used to make the onboarding flows? I like the simple UX intro, shows you what you can do, simple next and highlights the active screen
what do you call that type of UX and hows it made?

I've seen slighly similar presentations in LabView and/or Matlab. How does your project compare to them?
