Design Digital Circuits in Your Browser with CircuitVerse
Ever wished you could build and simulate digital logic circuits without installing a single tool? CircuitVerse lets you do exactly that right in your browser. It’s an open-source, web-based digital circuit simulator that works smoothly on any device with a browser.
Think of it like a digital breadboard for logic gates, flip-flops, and even microprocessors. No downloads, no setup. Just open the page and start wiring.
What It Does
CircuitVerse is a full-featured digital circuit simulator that runs entirely in your browser. You can create circuits using basic logic gates (AND, OR, NOT, etc.), combinational blocks (adders, multiplexers), sequential elements (flip-flops, counters), and even memory components. It supports both manual simulation (step through clock cycles) and automatic simulation for real-time behavior.
The tool also includes an integrated Verilog editor and compiler, so you can write hardware description language code and see the circuit behavior directly.
Why It’s Cool
No install required. Most circuit simulators need heavy IDEs or local tools. CircuitVerse runs in your browser, so it works on Chromebooks, public computers, or your phone.
Shareable circuits. You can save your designs and share a link. This makes it killer for teaching, demos, or collaborative debugging. No more sending screenshots or giant files.
Built-in Verilog support. If you want to mix schematic entry with HDL, CircuitVerse lets you do both. It even generates a schematic from your Verilog code.
Open source. The entire project is on GitHub. You can fork it, contribute, or even self-host if you need to run it offline. The codebase is Python/Django on the backend, and JavaScript on the frontend.
Real educational value. It’s used in actual university courses for digital logic design. The UI is intuitive enough for beginners but powerful enough for advanced projects.
How to Try It
You don’t need to install anything. Just go to the live instance:
Or if you want to run it locally, clone the repo:
git clone https://github.com/CircuitVerse/CircuitVerse.git
cd CircuitVerse
# Follow the setup instructions in the README
The README covers everything from Docker setup to manual installation. For most people, the online version is all you need.
Final Thoughts
CircuitVerse is one of those tools that just makes sense. It removes the friction of setting up a development environment for digital logic
