I’m not sure I’ve met a Jetbrains user in projects I’ve worked on. It’s a paid product so just has a small userbase.

Here are some numbers on their user base in real number and dollar amounts: https://www.jetbrains.com/lp/annualreport-2024/

Their tools are wildly popular in many spaces. It isn't for everyone though. It's totally believable in your circle no one uses their tools, but it isn't niche.

Funny enough, I know a lot of people who work at JetBrains, but only a few end-users.

Their use base is completely different. And we’re both in a bubble, I reckon. IntelliJ people also only know a few VSCode users!

Pycharm is extremely popular in the data science world. The Community Edition is free and has 99% of the features most people need. Even when developing with Cursor, I find myself going back to Pycharm just to use the debugger, which I greatly prefer to the debugger used in these VS Code forks.

Lately I’ve only tried clion, which has no free version. Personally it didn’t function as well as vscode for C++.

You may have missed it but they did release a free version of clion recently (for personal use). https://news.ycombinator.com/item?id=43914705
