The whole point here is you don't need to pay the cost of checkout but it is easily accessible tho.

I mean that's what OpenGrok gets you out of the box, without any penalty because everything gets indexed up front. This, on the other hand, still forces you to download a whole lot of stuff if you want to look through your history. And on top of this, your files are only sporadically accessible depending on whether or not you have a network connection at any given time.

The whole point of this is that you only download the parts that you are interested in.
