Fleet was a terrible product. I’m a long time jetbrains user and still use goland, rust rover, and clion. I was really excited when it got announced because I had had a lot of issues with vs code, extensions, and lsp at the time. I was hoping jetbrains was going to build something competitive but it never materialized. Rather than building something lightweight and fast on a native ui toolkit with faster analysis engines they basically built on top of a lot of the tech that was the bad parts of their existing IDEs. important features and the ability for community extensions to fill them never came to fleet which meant it never could replace other tools for real work and jetbrains seemed to focus on building LLM features to capture the hype rather than fixing the issues people have with their existing products. Instead they have mediocre ai features that are essentially commoditized and IDEs that are under invested in that are sluggish. In terms of full batteries included IDEs they’re still probably the best, but they’re losing a lot of the market.
