DESIGN, WIRE, AND TEST EMBEDDED ARCHITECTURES ENTIRELY IN YOUR BROWSER. NO SOLDERING. NO FLASHING. JUST LOGIC.
A COMPLETE EMBEDDED SYSTEMS SIMULATION TOOLKIT
Sensors, MCUs, actuators, logic gates, network modules, and power supplies — all simulated in real-time.
Visual node editor powered by React Flow. Drag components, draw connections, build systems intuitively.
Real-time signal visualization. Monitor pin values, track state changes, debug timing issues.
Inject sensor failures, network drops, stuck relays — test how your system handles the unexpected.
Write automated tests with our DSL. Assert pin states, wait for conditions, validate behavior.
Write custom JavaScript firmware for MCU nodes. Full access to inputs, state, and emit functions.
PRE-WIRED ARCHITECTURES TO JUMPSTART YOUR PROJECTS
Pick sensors, controllers, and actuators from the library. Drop them on the canvas.
Draw connections between pins. Set properties, write firmware logic for MCUs.
Hit RUN. Watch signals flow. Inject faults. Run automated test suites. Export results.
FREE. BROWSER-BASED. NO CREDIT CARD REQUIRED.
