We are Modeloop.

Modeloop is a model-based design IDE for embedded control systems, combining visual diagrams, textual models, simulation, testing, and code generation.

The current state of Model-Based Design is broken. For decades, engineers have been forced into a "Binary Era" — locked into opaque file formats, heavy desktop installers, and proprietary licensing servers that treat version control as an afterthought.

Modeloop is here to set your creativity free. We believe that engineering should be tangible and immediate. We’ve stripped away the over-engineering of legacy tools to build an environment so intuitive it feels like you've always known it. No friction, no black boxes — just a bridge between your imagination and physical reality.

II · Engineering Mandate

Why Modeloop exists,
in three movements.

Modern embedded software is shaped by three forces — the rigor of Model‑Based Systems Engineering, the cadence of Agile delivery, and the gravity of codebase scale. Modeloop is engineered to hold all three at once.

01 The Convergence

MBSE Rigor

Source of truth, not documentation.

Model‑Based Systems Engineering has historically meant heavy artifacts and static reviews. Modeloop reframes the model as a live, executable contract: every block is bound to a requirement, every connection is type‑checked, every change re‑validates the system in seconds.

Agile Velocity

Continuous integration, not waterfall.

Embedded verification has always meant multi-month cycles. Modeloop collapses them to seconds — generate the code, run the tests, on every commit and every branch, without leaving the editor.

↻ The synthesis The two principles are usually treated as opposites. Modeloop treats them as two halves of the same loop.

02 The Missing Piece

The V‑Model defines the shape of safety‑critical engineering. Modeloop closes it.

Specification descends the left arm. Verification ascends the right. Historically, a chasm runs between them — engineers manually translating models into code, then manually authoring tests against the code they just wrote. The chasm is where bugs are born. Modeloop replaces it with a generator: the model is the design, and the model emits both the implementation and the test harness that closes the V.

03 The Complexity Mandate

At nine figures of code, every keystroke is a defect site.

Modern embedded software has crossed a threshold. Manual edits do not scale linearly — they compound. A change in one file silently breaks an integration contract three layers away. A unit test passes while the integrated build regresses in ways no human reviewer can catch in time. At 10⁸ lines, the probability of a defect‑free manual change approaches zero.

What Modeloop Actually Does

From visual algorithms to microcontroller C code.

Modeloop is not just a canvas and it is not just a simulator. It is a model-based design environment to create, test and deploy your algorithms on embedded systems.
