Both are source available software [0], other than that you can't compare them. Krypton is fully proprietary nothing more nothing less, what RedisLabs did was a complete disservice to the whole open source phenomena without addressing any actual business concerns. They misinterpreted the whole clause thing to somehow say that your software can be both open and closed at the same time (it can't). They could at least had maybe done a minimal research and maybe learned somethings from Suns community source SCSL [1] or other similar liceses from the past and they even didn't bother doing that (the irony that SCSL is now hosted at Oracle speaks for itself).
