Who is the target customer? Some of the features seem interesting and useful, like domain-specific syntax highlighting, Definition tooltips.
The site talks about accessibiltity and inclusion, but doesn't expand on what that actually entails.
All of the "Explore" links just download the app instead of expanding on the feature.
I mean, this looks like it could be a nifty product, but as others have said, you must be clear about wetting your target audience in the first screen of the page, and then provide details about what are each of the features.
You can't rely on people installing it to understand if it's for them. You got to make them _think_ it's for them first, then they'll download it and take the time to try it.
There are lots of small psychological hurdles to overcome before someone decides to install a piece of software and commit time to trying it. Downloading it going to require me to clean-up the setup file at some point, maybe it's a messy install, and it's going to be a pain to uninstall, maybe it's not really safe or could be a security hazard or mess up with other parts of my system, or it will just crash, maybe it requires libraries or runtimes that I don't have on my machine (jre?), maybe it will require an account, and I'm not ready to create one, maybe it's complex to use and I'm just going to waste time, maybe it's really targetted at lawyers and won't fit my industry, maybe...
[edit]: so I downloaded and ran the setup and Windows Smartscreen barked at me, and now I have to bypass that safety net. I hate Windows Smartscreen and will force through for software I know to be safe (like grafana), but I know nothing of this software, and I'm not sure I should force its installation. A major hurdle. Maybe having a separate page show up when downloading for Windows, explaining Smartcreen could popup and how to bypass it would help non-techie users?
