kotlin-lsp

It's a bit strange to project a personal experience with one product onto all other products by the same vendor, even if those products use shared platform parts. Not to dismiss your claim, it's just IDEs (code engines specifically) are naturally pretty complicated pieces of software, so the experience may vary. The claim that 8Gb RAM is required just for Intellij seems to be at least overgeneralization (also depends a bit on how you count RAM usage; e.g. do you count all mmaped files as RAM usage even when pages are not loaded?). Can be true for some projects, but I've been working on decently sized Java/Kotlin codebases (~250k locs) with way less RAM allocated for Intellij (again, your experience may vary). Even Intellij and Kotlin projects themselves have been usable with less memory, at least some time ago. What's more baffling, thoug

My org had to write a pivotal backend service on the JVM, due to JDBC having the largest number of data source adapters. The choice was Kotlin. Scala is too "powerful" and can be written in a style that is difficult for others, and Java too verbose. Kotlin is instantly familiar to modern TypeScript/Swift/Rust etc devs. The only negative in my mind has been IntelliJ being the only decent IDE, but even this has changed recently with Jetbrains releasing `kotlin-lsp` for VS Code https://github.com/Kotlin/kotlin-lsp

As of somewhat recently, Kotlin has a language server: https://github.com/Kotlin/kotlin-lsp Using it in vscode, while not perfect yet, is starting to be alright.

Jetbrains is working on an LSP: https://github.com/Kotlin/kotlin-lsp It was announced at KotlinConf 2025.

this will change, Jetbrains is working on a Kotlin-LSP, just don't expect it to be done anytime soon: https://github.com/Kotlin/kotlin-lsp

at the (semi-state owned) company (in Germany) I work at, Kotlin is a first-class language also for backend. It depends on the teams wheather they prefer Java or Kotlin. I'm firmly in the team-Kotlin camp and Java code that becomes my responsibility has the strong tendency to suddenly become Kotlin code. By the way, I never worked on Android, so all my Kotlin work (since 2019) was server-side Kotlin. Java is getting better, so maybe in 10 years it'll be a less ergonomic Kotlin variant. PS: Jetbrains - the company behind Kotlin - started a strategic partnership with the Spring team, to make the combo Kotlin-Spring even better: https://blog.jetbrains.com/kotlin/2025/05/strategic-partners... PSS: Jetbrains is actually working on an official Kotlin-lsp server: https://github.com/Kotlin/kotlin-lsp So devs in the near future won't be locked int

I agree, but I can strongly recommend Claude Code with the Intellij plugin. Actually works pretty great for kotlin! And, JetBrains finally started working on an open language server. It's not perfect but it makes it bearable to at least edit Kotlin in Cursor/VS Code. https://plugins.jetbrains.com/plugin/27310-claude-code-beta- https://github.com/Kotlin/kotlin-lsp
