Best Open Source Software Options for PCB Design: KiCad, Fritzing, LibrePCB

What are some best open source  software for PCB design ?

I'm not aware of any open source PCB design software, so this may not help you, but for what it's worth: My company outgrew the capabilities of the PCB design package we were using, so we spent several months evaluating all of th packages we could find.We discovered some really good free ones, but they all lock you in to ordering the PCB's from one specific company so we ruled them out.We found some really good ones that had a steep learning curve and were very expensive.  Then we discovered Diptrace and fell in love with it. It had all of the features we needed and was easy to learn.  They've got a very active and helpful forum in case you have questions.  There's a huge library of pre-defined components, but if you need one that's not in the library it's easy to create your own.I have never trusted autorouters until I tried the one that's included in Diptrace.  Yes- it does still need some tweaking after it's done its job, but it saves me a tremendous amount of time.They have a free 300-pin version for home or non-profit use, and 30-day fully functional evaluation version.  Pricing for the purchased versions starts at $75.00.In case you're wondering- I'm not associated with the Diptrace company in any way- I just really like their product.-Rick

There's one software I would recommend, and that's KiCad. Free open source software. Worth checking out.

By the way- Just because I like Diptrace doesn't necessarily mean it's right for you. It's very much a matter of personal preference- which one "feels" most intuitive.Hopefully, others will chime in with suggestions.  I encourage you to download evaluation versions of Diptrace, Eagle, Kicad, Orcad, PCB123, Circuitmaker, etc. and see how you like them. -Rick 

The two open source PCB design software that I know of are gEDA and KiCAD
http://www.geda-project.org/http://kicad-pcb.org/I haven't used either so I can't comment on usability.I've used Diptrace and while it's very capable, I can't say that I love it. But then I've been spoiled by the very high-end (and very expensive) tools we have at work.
Eagle seems to be what a lot of open-source / hobbyist folk use. Unfortunately, they were bought by AutoDesk and the AutoDesk web site appears to run afoul of my anti-spyware add-on...

There is a company called Upverter who have web based free schematic/pcb tools. They were recently acquired by Altium and I just received an email stating "Since joining Altium last summer we’ve been hard at work on a new version of Upverter. We’re getting close, and would like to give you a sneak peek, talk about what you’re working on, ..." I was not enamoured of the product back when I evaluated it, but as Elizabeth says, I have worked with some expensive software and am set in the old way of doing things. 

There is no such thing as best, it depends on what your perceived need are, as well as the operating system you are using. If you are going to do a PCB, then some idea of what your requirements are would help. Additionally, you may quickly outgrow a low end package, so it helps to have some idea of where you may  be headed in the future. The reason is quite simple, despite what all the vendors or suppliers say, there is always a learning curve, some are quite steep, so you have to invest quite a bit of time to learn how to best use whatever you choose. Secondly, there is a big investment in creating libraries, which are  often not transferable to another package if you decide to change. It can therefore be worthwhile exploring that feature carefully when choosing a package, since some have extensive libraries, or have the ability to download them from web sites. Don't rely on the libraries to be accurate, you need to check the part against the data sheets to be sure on the first use.Cloud based packages need a good internet connection, and your design files may not be secure, which may have commercial implications.There is a link here which may be of some help,https://www.circuitsdiy.com/best-free-pcb-design-software-list/
I personally use PADs, a commercial package, that was a decision forced on me many years ago, I am now very familiar and comfortable  with it, and have a vast library of parts and fixtures, like any package, it has its quirks and quite a learning curve. There is a free very limited addition available through DigiKey which is not in the list above, but it's not open source, so doesn't meet your criteria.
Cheers,Richard

A further comment, something that was alluded to in an earlier post. Some of the free packages are tied to a specific pcb manufacturer, and use  propriety output formats suited to there manufacturing process. If any of them allow a Gerber file to be exported, then in theory they would work for you as well,cheers,Richard

I last used PCB which is part of http://www.geda-project.org/ mentioned above by Elizabeth. I ran PCB on Linux, though I haven't used it recently so I can't report on the latest versions. One advantage of PCB was that the internal data formats are in plain ASCII text, so I can make changes with a text editor. This is particularly useful for making library parts using a text editor, a feature the original MS-DOS Orcad had (later Orcad versions removed this capability, requiring the more-awkward-for-me use of gestural interface to annotate library parts).gEDA also includes a Gerber-file viewer, gerbv.http://repo.hu/projects/pcb-rnd/ is an actively-being-developed fork of PCB, which I have not yet tried.

For boards of spiral antenna coils, years ago, I wrote my own C code to directly output Gerber files. This allowed me to numerically specify what I wanted, and also output the coils' geometry in a 3D format for electromagnetic modeling.

If you are only after schematic capture, I just discovered a schematics entry tool on EE Web that is part of a schematic converter from a company that seems to be called Transim.
There is also pcbWebthat is "a free CAD application for designing and manufacturing electronics hardware"You can see both of these plus a host of other useful tools off the the right on the EE Web home page as well as here..

Digikey lists several free and low cost options here.They also have a schematic editor Scheme-It

There is free ORCAD in the cloud via Arrow

Thank you so much for your suggestions. It helped me lot to decide pcb design software to be used. After reading it I decided to use kicad. Because it is open source software.

I think the eagle is the best to do this.This days i have buy some PCBs from PCBGOGO which is a best PCB factory in China.It will arrived to Indonesia 5 days later.I can't wait it i will have a new project.
Have a guess!

Thank you very much for the information. Very helpful.
