ExoSynk is under maintenance. We're rebuilding it from scratch — the Circuit Editor and Signal stay open while we work.
ExoSynk · by ExoSynk LabsDesign electronics in your browser.
ExoSynk is a virtual electronics lab for anyone who designs circuits. Wire up parts, write Arduino-style code, simulate it and watch it work — then, as we grow, order the real thing. It's made by ExoSynk Labs, and we're relaunching it step by step.

The product
What is ExoSynk?
A browser-based workbench for electronics — for students, hobbyists, makers, teachers and engineers. No install and no parts to buy before you know your circuit works.
- Open now
1. Design
Drag batteries, resistors, LEDs, sensors, op-amps and an Arduino Uno onto a grid and wire them pin to pin in the Circuit Editor.
- Open now
2. Simulate
Real circuit math (Modified Nodal Analysis): see voltages and currents, LEDs light up or burn out, probe with a multimeter and oscilloscope.
- Planned
3. Build
Save each design as a repository, share it, and later order it as a parts kit, as a pre-built product, or from a marketplace of designs.
Open during maintenance: the Circuit Editor and the Signal feed. The 3D Editor, public repositories, tutorials and the store come back one at a time.
The studio
Meet ExoSynk Labs
ExoSynk Labs is the independent studio behind ExoSynk. We build focused software that respects its users: ExoSynk for electronics, and small offline-first apps like XPENC and XPENC Business for money and PLANR for your day.
Started by Yash Patil in Kolhapur, Maharashtra, India.
