Keenetic OS is an OS for routers based on OpenWRT with modifications.
Is it any better than OpenWRT? Yes, if you have Keenetic router with USB, ig? If we are speaking about end user who doesn’t want to modify OpenWRT image and host some servers or doesn’t want to make patches for kernels. While Keenetic allows this with Keenetic-SDK, KeeneticOS is more than easy for most end users.
Keenetic SDK? What’s it? Keenetic SDK is something like build system from OpenWRT, with Keenetic modifications.
