Circle software is built using some GNU GPL (General Public License) software components along with some non-GPL components. We want to make sure that the source code for these GPL components is readily available to those that are interested (whether for the sake of curiosity, security concerns, for education, or otherwise).
Circle-branded Product
If you're interested in reviewing the GPL software components that make up Circle, you can check the source code out for those HERE.
The Circle device also runs on an operating system called OpenWRT which is an AMAZING open source project based off Linux and is mostly used for networking. You can download the full source code for that HERE and learn more about it at their website.
You can also view our version of the open source boot loader, U-Boot, HERE.
Sky Broadband Buddy
If you're interested in reviewing the GPL software components that make up Sky Broadband Buddy, you can check out the source code HERE.
If you have any concerns or question about the security of the Circle device or software components please reach out to us at security@meetcircle.com. We want to make sure those are taken care of as far as we can.
