DataGrip is $20 a month for more features. However, after you've paid for 12 months you get perpetual access, so you can essentially pay for 12 months (or yearly at $199) and it essentially becomes a one-time license to that version if you'd rather not keep paying.

(I've been a DataGrip customer for a couple of years now)

Also gets cheaper on 2nd and 3rd year.
