I think Fleet's their hopeful answer to VSCode. IntelliJ is powerful, but so, so messy, with a convoluted UI from the 90s/2000s. Even the simplified one is much klunklier than VSCode, especially for everyday/every-hour tasks like NPM scripts, debugging, etc. Every essential function is hidden in tiny competing side panels triggered by some obscure icon in a different part of the screen. I love and use Jetbrains IDEs…

I'm the opposite, vs code feels so clunky to me and full of crappy bolted on low and mid quality plugins. Yes it's lower barrier to entry on making things and for editing configs but the configs are opaque, hard to find. Odd for microsoft that it's more of a linux mindset than windows. It feels so janky setting up run configurations or test runs.

Not to mention it hardly seems to support simply running things from package.json script section when doing JS stuff. Every time I try it seems to never quite work, or is very clunky and obtuse, sometimes requiring the creation of new files (???) to do it.

Compare that with the other main IDE I use, Visual Studio. It works great.

What would HN be without the agism and nasty remarks that somehow are always initiated by colour and theme preferences.

Grow up.

What would you suggested instead of JetBrains tools for AI-assisted development? (I don't just want to hear what everyone says; I specifically I want to hear what JetBrains lovers think about this.) I was about to go all in on JetBrains becaue I can't stand VSCode, and about to transition from ChatGPT only to trying out in-IDE integrations... but if there's a better thing to try first... all ears.

JetBrains is WAY behind VS-Code and its forks (e.g. Cursor) in terms of AI features. Their own offering, "Jetbrains AI" absolutely SUCKS (just read the reviews, you'll see why). Third-party AI plugins are pretty basic. Most just offer inline completions and a chat sidebar. For example, GitHub Copilot for Intellij is a shell of itself: No agent capabilities, or even model switching (although that seems to be coming in…

> Most just offer inline completions and a chat sidebar

As someone who doesn't use AI all that much: what else does an IDE need besides an inline prompt and a ChatGPT window to the side? I've played around with the continue.dev plugin and I can't think of anything else I'd want out of AI assistants with the quality they're at at the moment.

> GitHub Copilot for Intellij is a shell of itself

That's on Github, to be honest. And to be expected. It doesn't make much sense for Microsoft to fund a plugin for a competitor's IDE when they already have their own IDEs to sell.

> Intellij products are closed source

They follow the same protocol Microsoft uses: the core is open, but some language plugin features are proprietary. For Microsoft, the proprietary part is just the C# debugger at this point, whereas IntellJ has a whole bunch of paid-for plugins that are closed-source. Still, you can fork the community edition of IntelliJ should you wish.

I still don't understand where Jetbrains is going with Fleet. Is it a platform to prototype ideas for their IDEs? Is their long-term goal to replace their IDEs with Fleet? Is it just a standalone product? So far, it seems like they're very slowly recreating their IDEs from scratch in Fleet while continuing development on the IntelliJ Platform and related IDEs, doing twice as much work for nothing.

"doing twice as much work for nothing" - it's precisely right

Most comments here either praise IDEA-variants as "outstanding", or blame it for being "slow and complicated", both of which feel odd to me (especially the first one). I strongly prefer JetBrains products over anything else, so if it's possible to use PyCharm, I will use PyCharm instead of Vim/VSCode. Yet I cannot imagine calling it outstanding. Maybe, that's just my bad character overall, but I just am surprised why…

> I cannot easily add a couple of my own simple refactorings

While this isn't as powerful as the full plugin API, there is Edit > Find > Replace Structurally which can be used to write some pretty complex code alterations, and you can save/load templates to reuse them later.

IMO Jetbrains IDEs are the best IDEs. That doesn't make them amazing or great or outstanding. They have their bugs, their resource leaks, and sometimes just plain weird design decisions, but they're ahead of the competition by a long shot for many programming languages. Other IDEs can match what Jetbrains has to offer, but you have to install and configure every feature yourself, while the Jetbrains stuff mostly comes with batteries included.

I wish Jet brains would give AI features for free for some time, Github co pilot will be incompatible with fleet for some time and even with other legacy jetbrain IDEs like webstorm / pycharm it does not work very well. They always release features for vs code first and then webstorm follows.

CoPilot has been working fairly well for me in GoLand. I don't know if Copilot has the same or more support in Goland than in Webstorm/Pycharm, so, if the latter, my observation might well be disjoint from yours. But so far, it's a moderately capable assistant. My biggest complaints with it have more to do with its responses than its fit with the IDE.

Copilot in VS Code has model options, the new agent is available in VSC Insiders that will implement full features and show it's changes in a diff viewer. Jetbrain IDEs don't have the option to change models

I believe they are heavily reusing the non-UI part of Intellij and the like, so it's not really 2x the development.

Usually Intellij products are slow and fleet does not seem to be slow, so it is feels likely a lot of code was rewritten to make it fast.

I don't think they're slow at all. Takes a while to index when opening a new project, then everything is snappy.

My main reason for using JB is I loathe the shitty build your own ide experience of VSC. Everything is more difficult, whereas in JB everything just works.

You forgot to add "IMHO". IDEA has fantastic UI, it's fully configurable and 100% usable through pre-assigned hotkeys. For example, fuzzy search is available everywhere , in every tool window, in the database window, in search results, etc. The same key combination (ctrl+alt+arrow up/down on my instance) can be used to jump between search results, symbol usages, TODOs, linter results, and so on. They thought through…

>You forgot to add "IMHO"

But also objectively.

That's on you. What it comes with is great. And there's a huge selection of good third party plugins if one takes attention to what they install.

Sadly not, as Clion is not available as a plugin like almost all other IDEs: https://www.jetbrains.com/products/compare/?product=idea&pro...

Thanks!!! I also saw your other post about C# - maybe one day JetBrains would change their mind! I'm trying latest IDEA (2025.1 EAP) and for the first time a bazel project that I have got parsed successfully (had to enable some old legacy flag though), so there is hope!

Did you use the google plugin or the new BSP based one by JetBrains?
