KiCad Vs Altium Designer | What’s Best For PCB Designing

Considering the number of PCB design software available in the market today, it is definitely tricky choosing the right one. Hence, here we have done an in-depth comparison between KiCad vs Altium Designer.

Perhaps the main difference in these two is that one is a free application, while the other is paid. Altium and KiCad both have been in the market for more than a decade and hence have gone through refinement and upgrades to become much better over time.

KiCad and Altium are two widely used software platforms for schematic capture and layout. These two are very different kinds of programs, but their essential features are the same. To understand the main features and differences, read our complete guide on comparison between KiCad EDA vs Altium Designer.


KiCad is one of the most promising EDA (Electronic Design Automation) programs currently. It is a free software suite with great features and performance. KiCad has been in the market for nearly three decades now, since its initial release in 1992.

It offers tools that can be used for schematics and layouts for circuits and PCB designing. Unlike lots of other free software, this provides some advanced tools such as BOM (Bill of Material) generation, artwork creation, Gerber format files and even 3D modeling and rendering.

Another great thing about KiCad is that it is a multi-platform suite. You can install and use it on Windows, macOS and Linux as well, free of cost. This package contains five main components:

  1. KiCad: (Project Management)
  2. Eeschema: (Schematic Capture and editor)
  3. Pcbnew: (PCB layout solution, with 3D capabilities)
  4. GerbView: (Gerber viewer)
  5. Bitmap2Component: (Image to PCB footprint conversion)

KiCad integrates all the above tools to provide the user a central design environment.  Let’s take a look at the main features of this program.

Comparison between KiCad Vs. Altium Designer


The highlights and key features of KiCad are discussed here.

  • Schematic Capture with Eeschema: KiCad provides an elegant and functional schematic capture solution, with all tools available as you may require. The interface is neat and functional, with a focus on essential tools. It also offers hierarchical conversion for complex designs, which simplifies multi-sheet schematics into sub sheets. All major export formats are supported: PDF, SVG, HPGL, Postscript.
  • Electrical and Design Rule Check: KiCad also offers a powerful ERC and DRC system which checks for errors such as output pin conflicts, missing drivers and unconnected pins. The netlist export options allow designers to save their netlists in various formats such as Pspice, Cadstar, PcbNew, XML.
  • Layout and Routing with PCBNew: PCBNew allows faster and more efficient routing. With features like push & shove routing, the software clears the obstacles by pushing forward traces. Alternately, the obstacles can be ignored, and the program can do rerouting. This system works with DRC compliance.
  • 3D Viewer: With KiCad, users get 3D viewing capabilities, interactive viewing and even the option to view 3D models as two-dimensional drawings, for easier understanding and understanding part details.
  • Open Source and Cross-Platform: KiCad is an open-source software program that allows users and developers to constantly debug and improve the platform, which means faster upgrades and improved features. This application also runs on Windows, macOS, and Linux systems as well.
  • Simple User Interface: KiCad has an intuitive and easy-to-use interface which helps novice users learn designing and improve their skills quickly. The learning curve is also really simple, thanks to the tutorials provided with a focus on essential tools and speed of working.
  • Library Import Feature: Although KC offers a large variety of pre-built components in its libraries, you still might have the need for some additional components. Now, to save you the time of having to build those parts yourself, KC allows you to import them from external sources.
  • GerbView Functionality: The GerbView package of KC supports modern canvases such as OpenGL and Cairo. The new version also features a new measurement tool, along with support for loading Gerber X2 extensions and job files.

Why Choose KiCad? (PROS)

  • The hotkey functionality, which allows users to define shortcuts for easy access to frequently used functions, is a great feature for productivity.
  • Being a completely free program, the performance and variety of features is commendable.
  • Eeschema with ngspice integration now provides SPICE simulation support.
  • Symbols and nets can be moved between hierarchical sheets using the partial clipboard support function.
  • Better navigation and preview tools with improvements such as cross probing with highlighting and a custom colour selection feature.
  • To help users manage internal environment variable, KiCad now provides an environment variable editor.


  • The library management features in KiCad need improvement and need to be centralized. There is limited part availability while working with newer or less common components.
  • macOS users might face certain latency issues on some older KiCad versions.
  • KiCad does not have autorouting or high-speed feature design support.
