@angelena Here's my suggestions:
1) Pricing is way too confusing. Do you really need 6 pricing tiers?? It's information overload for sure.
2) iFrame background of the help chat being white looks bad. It's also overlapping the "got it" button on my screen so I can't close the cookie footer.
3) On the homepage, your code being in frames that you have to scroll looks ugly. Mobile is even worse... Maybe try giving it more room. 1/2 looks a lot better than 1/3 IMO.
vs
(potentially even adjust the height to fill so there's no scroll bars at all). At least for the above-the-fold code.. the rest you can potentially leave with scroll bars if you need to.
4) On your docs page in dark mode, the logo has a white outline. Now that I mention it... your logo is looks like a block of butter. What is that supposed to be?
5) On the dashboard page, same issue with having to scroll to see all the data. I probably don't need to see the key at all times on that page.. you could probably just make a popup when I click it that shows the whole thing. Also bad opsec to show keys like that on a dashboard (sharing screen, in a coffeeshop, etc)
6) On your quickstart in your docs, under "Making your first API request", you call the cURL "Code". I would just call it "cURL". Also I would break it up into lines... ie the way stripe does it:
https://docs.stripe.com/api/payment_methods/update?lang=curl
Maybe just me, but the first thing people will do to play around with an API is probably just make some calls using cURL to make sure it will work for them before they install anything and set up a project.
