What's New in the Beta Web Editor

February 19, 2025

The Beta Web Editor has some new updates:

The new History panel shows every change made to the circuit in the current session.
The new Wire tool lets you place multiple wire segments at once. Right click to complete the wire.
Use the Text shape tool to add multi-line text to a circuit.
Star components from the components page and they will appear automatically in the toolbox.
Changes will be autosaved if you are signed in and the circuit has been previously saved.

The local components feature has been removed but may return in a future update.

Extended Components Library

July 1, 2024

The Extended Components Library is a new project providing a additional component symbols to use in Circuit Diagram.

Find it on GitHub at circuitdiagram/ext-components.

Introducing Circuit Shaders

March 18, 2024

Circuit Shaders are a new way to extend the functionality of Circuit Diagram by adding effects and modifying the appearance of circuits.

Written in Python, they can do things such as:

Change the color of circuit elements
Apply formatting to text
Render new elements
Change the thickness of wires
Change how connection points are rendered

Check out the available shaders in the Shader Gallery.

Web Editor Beta

August 28, 2023

We are excited to announce a new version of the Web Editor has recently been in development and is now available to try in a closed beta.

The new Web Editor has been re-written from the ground up and features a number of improvements including a new dark mode.

To be among the first users to try the new editor, follow us on Twitter @Circuit_Diagram where we will be sharing invite codes to join the beta.

New Web Editor Features

January 5, 2020

The Web Editor is regularly updated with new features and improvements. Here are a few of the new features that have been added recently.

Copy and Paste

Cut, copy and paste components and layers between circuits using the keyboard shortcuts Ctrl+X, Ctrl+C and Ctrl+V.

Resistor, Inductor and Capacitor Improvements

These components can now display both their text and value properties at the same time.

Adding More Components

Many components are available by default in the Web Editor, but for even more, click on the Add more components button.

Circuit Netlists

April 3, 2019

Circuits created using the Web Editor can now be viewed or exported as a circuit netlist.

Netists describe how components in a circuit are connected together, and are commonly used for circuit analysis, simulation and PCB design.

The circuit details page also shows a rendered view of the circuit with each of the netlist nodes marked on the circuit visually.

The above circuit is represented by the following netlist:

V1 1 0 5
R2 2 0 220
R3 1 2 220

Colored Circuits

January 1, 2019

The Web Editor now supports creating color-coded circuits:

After placing a component, use the color picker in the Layers panel to set the color.

Visual Studio Code Extension

May 7, 2018

Build custom components in Visual Studio Code with the new VS Code extension.

As an additional option to using componenteditor.com, you can now use Visual Studio Code to create and edit custom components.

The extension is currently available as an early preview. It provides the following features:

Show component syntax errors in the VS Code editor
Render a preview that can be viewed in VS Code

Circuit Simulation

April 7, 2018

Simulate your circuits using the new simulation functionality in the web editor.

After clicking the simulate button, you will be presented with a snapshot of the simulated version of your circuit. This displays the voltages at all of the connection points in your circuit, and any components with dynamic behaviour will be rendered appropriately. For example, the Lamp will be lit if there is a voltage difference across it, and the 7 Segment Display will illuminate to show the input number.

Please be aware that this is a preview service and currently only supports a limited number of components. You might also experience some circuits that cannot be simulated while we are still working on improving this new feature.

Below is a copy of the simulation output from the Simulation Demo circuit:

New Web Editor

March 26, 2018

The web-based version of Circuit Diagram has been redesigned and is now available to use. The new and improved features are:

Improved interface
Undo/redo functionality
More components
Larger document size
Improved property editing
More download options including PNG and SVG

You can share links to circuits, and publish them on the circuits section.

Get link will provide a link to your circuit without listing it in the circuits directory.

Publish will make your circuit available for others to view in the circuits section.
