Build, visualize, and simulate systems — together
An open platform for system engineers and collaborators. Create public diagrams with real logic, fork and enhance others' work, and watch systems evolve transparently.
Join the waitlist for early access. No spam, ever.
Everything you need to model systems
Designed for engineers who think in systems. Built for collaboration.
Diagram Editor
Create intuitive flowcharts, networks, and models with a powerful visual editor.
Node Logic
Go beyond shapes. Nodes store data, logic, operations, and formulas.
Reusable Blocks
Access libraries of modules for energy, robotics, data flows, and more.
Collaboration
Comments, forks, merges, and shared feeds. Work together seamlessly.
Execution Layer
Test scenarios, run models, and validate designs in real-time.
Open & Public
Browse, contribute, or build upon existing work. Knowledge for everyone.
Why Open System?
We believe engineering knowledge should be open, collaborative, and alive.
Living Systems
Transform static diagrams into dynamic systems that can be tested, simulated, and validated before implementation.
Public Knowledge
Build a comprehensive library of engineered knowledge. Learn from others, share your expertise, advance together.
Unified Workflow
Research, design, and collaboration in one platform. No more switching between disconnected tools.
