Earlier this year I finally bought a decent keyboard (Kinesis Advantage). While I was searching for what I wanted, I put together a list of keyboards with some features and have just put it online. Hopefully it can help others in search of a good keyboard. I'm sure the list is incomplete (both in terms of keyboards and listed features). I'll be adding keyboards in the coming days. Feel free to give feedback and suggestions if there are certain things missing.

(e.g. I was thinking about adding filter for cherry mx key color)

It is a pretty comprehensive list of desirable (non-gaming) keyboards, but I'm not sure that many of them fit the description of "ergonomic" at all.

This keyboard is basically the ultimate version of what your list tries to compile: * Ergonomic (split) * Hackable (macros and programmable keys) * Mechanical

It's not out yet, but you can pre-order one.

In a similar vein, there is https://shop.keyboard.io/ I pre-ordered one earlier today to replace a TECK.

I agree that most of the keyboards on this list are not ergonomic at all. Most are simply mechanical keyboards.

Thanks for building this. I made a similar (but much simpler) list a few years ago when I was searching for an ergonomic keyboard. Your site would have saved me some time. I'm missing the ErgoDox in your list BTW.

Thanks for the feedback! The ErgoDox is indeed one that's on my todo list =), along with the unicomp, ultimate hacking keyboard and a few others.

I've seen no controlled research that any "ergonomic" keyboard is any better or worse than any other keyboard. Taste-wise, of course, some are clearly better than others, but different people can have different taste.

Is there any science behind this? I don't count "studies" paid for by keyboard makers to be legit --I mean controlled third party studies.

No ISO layout filtering.
