The best open source alternative to Schematics is KiCad. If that doesn't suit you, our users have ranked more than 25 alternatives to Schematics and 12 is open source so hopefully you can find a suitable replacement. Other interesting open source alternatives to Schematics are Fritzing, QUCS, LibrePCB and gEDA Project.
KiCad is an open source software suite for electronic design automation (EDA) - designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by Jean-Pierre Charras. And features an integrated environment between schematic capture, bill of...
Open-source initiative aiding designers, artists, and researchers in transforming prototypes to actual products, documenting circuits, sharing, teaching, and PCB manufacturing.
The Quite Universal Circuit Simulator (QUCS) is an integrated circuit simulator allowing the simulation and graphical presentation of results of large-signal, small-signal and noise behavior in circuits.
LibrePCB is a free EDA software to develop printed circuit boards. It’s currently under heavy development to bring out first stable releases as soon as possible.
The gEDA project has produced and continues working on a full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production.
This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It's very helpful for experimentation and visualization. It's a desktop version of the Circuit JS.
Qucs-S is a spin-off of the Qucs cross-platform circuit simulator. "S" letter indicates SPICE. The purpose of the Qucs-S subproject is to use free SPICE circuit simulation kernels with the Qucs GUI.
Circuit Diagram is a free application for making electronic circuit diagrams and exporting them as images. Design circuits online in your browser or using the desktop application.
eSim (previously known as Oscad / FreeEDA) is an open source EDA tool for circuit design, simulation, analysis and PCB design.
TinyCAD is an open source schematic capture program for MS Windows. Use TinyCAD to produce professional circuit diagrams and export net list information to PCB applications.
PCB Elegance is a suite of circuit board design tools for Windows. Including schematic capture, board layout, and manufacturing file generation. First released in 1998, it was proprietary software until 2012, when it was released as open source software under the GPL.
oregano - An electrical engineering tool for GNOME
oregano is an application for schematic capture and simulation of electronic circuits. The actual simulation is performed by Berkeley Spice, or GNUcap or the new generation ngspice which is required for simulation, but not neces.
