I took a gamble on the Moonlander by zsa. It's expensive but a really nice keyboard and instantly helped wrist aches and pains from long days developing.
There are alternatives that are cheaper, and even DIY ones which are cool too - but if you want a prebuilt split ergo I highly recommend it.
Took me roughly 1-2 days heavy use to get used to it and I've never looked back - I'm a huge fan of the ortholinear (technically columnar on moonlander) layout, it really does make natural sense imo with less finger movements laterally at awkward angles.
