Modeloop is in Closed Beta. Join the waitlist for early access.

The Future of Systems Engineering

Models as Code.
Software as Workflow.

Modeloop is the only visual environment that brings modern DevOps — Pull Requests, CI/CD, and total transparency — to model-based design for robotics and embedded systems.

Git-Native PRs, Diffs & CI/CD for your models

Modern Engineering Workflow

Stop using 1990s tools for 2026 problems. Modeloop brings the DevOps revolution to model-based design.

The Only Tool for Model-Level Pull Requests

Modeloop is unique. We don't just store diagrams; we enable a modern workflow. Submit a Pull Request for a model change, and your teammates can review the logic changes with semantic visual diffs.

Native CI/CD for Systems

Integrate your models directly into your GitHub or GitLab pipelines. Automatically run simulations, verify requirements, and generate code on every commit. No human intervention needed.

Designed for Delight (UX)

Systems engineering doesn't have to be ugly. We've spent thousands of hours perfecting an interface that is fast, responsive, and intuitive. From senior architects to new grads, everyone loves the Modeloop experience.

Built Different, For a Reason

Every feature was designed to eliminate a specific pain point in embedded systems engineering.

01 MODULARITY
SUBSYSTEM Σ × in out

Hierarchical Containerization

Without Modeloop: In C, nothing stops you from connecting everything to everything. Spaghetti is the default.

Wrap any subsystem into a single block with explicit inputs and outputs. Reuse it anywhere. Modeloop makes modularity the path of least resistance — at any scale.

02 STATE MANAGEMENT
Idle Running Done start done reset

Visual State Machines

Without Modeloop: Writing nested switch/if-else for FSMs by hand is error-prone. Edge cases get missed. Bugs live at transitions.

Embed StateCharts directly into your signal flow. Hierarchical states, event-driven transitions, every corner case visualized — before a single line of C is generated.

03 SIGNAL ROUTING
temp pres spd stat volt SensorBus 5 signals

Bus Management System

Without Modeloop: Passing 50+ arguments to functions or managing massive global structs. Change one value, risk breaking everything else.

Group hundreds of signals into a single Bus line. Update one field inside a complex bundle without touching the rest. Object-Oriented wiring for embedded systems.

04 LIVE CALIBRATION
BEFORE edit #define recompile reflash restart test ≈ 15 min MODELOOP CALIBRATION Kp = 2.4 < 1ms

Live Parameter Tuning

Without Modeloop: Gain too low? Stop → find #define → recompile → reflash → restart. Feedback loop: 10–15 minutes.

Mark any value as CALIBRATION. Change it at runtime via dashboard, JSON, or script — no recompile, no reflash. A 15-minute engineering cycle collapses into milliseconds.

Performance Without Compromise

Our simulation engine is optimized for intensive workloads, ensuring real-time decimal precision across every platform.

Engineered for Critical Systems

Transparent, reliable, and qualified for the most demanding industries.

Functional Reliability

Our C-Code Generator is architected for predictability and performance. We focus on **Deterministic Execution** and rigorous validation.

  • 100% Deterministic Signal Flow
  • Zero Dynamic Memory Allocation
  • Fixed-Step Solver Precision

Mathematical Truth

Modeloop utilizes advanced Back-to-Back Testing to ensure the generated C code behaves exactly like the Python reference.

Numerical Precision
ε < 10⁻⁷
*Verified across 100+ Golden Models.

Data Sovereignty

Your models and intellectual property never leave your machine.

Modeloop runs entirely local (via Electron or Pyodide). We do not upload your diagrams to cloud servers for simulation or code generation, ensuring maximum confidentiality for industrial R&D.

Modeloop is built by engineers, for engineers. We prioritize transparency and deterministic behavior in every line of generated code.
