de:volt Documentation
de:volt is a browser-based electronics prototyping and circuit simulation tool. Design, simulate, and iterate on circuits in real-time — no downloads, no setup.
What you can do
- Build circuits on a virtual breadboard with 58+ components: resistors, capacitors, LEDs, Arduino boards, 555 timers, logic gates, and more.
- Run live simulation at 60 Hz using a pure-TypeScript Modified Nodal Analysis engine running in a WebWorker.
- Save projects to the cloud with Supabase-backed persistence.
- Visualise signals with the built-in oscilloscope and live probe plots.

Status
de:volt is in public beta. Cloud saves, magic-link auth, and the full component library are live at sim.devoltapp.com. Billing, Arduino simulation, and the Learn mode are coming in upcoming stages.
