What is kotlin-lsp?

kotlin-lsp is a Rust-based LSP server for Kotlin and Java that delivers fast go-to-definition, hover info, dot-completion, and references without firing up a JVM. It indexes large Android or JVM codebases instantly at startup, staying under 200MB memory even for 10k+ files, and falls back to ripgrep for unindexed symbols. Install via `cargo install kotlin-lsp`, add fd and ripgrep to your PATH, and plug it into Neovim, Helix, or VS Code for lightweight navigation.

Why is it gaining traction?

Unlike JetBrains' kotlin-language-server or fwcd's JVM-heavy alternative, this starts in milliseconds and sips memory, making it ideal for sluggish large repos where official LSPs lag or balloon to gigabytes. Developers notice snappy dot-completion on repo objects, stdlib hovers like `run` or `map`, and superclass-aware jumps without compiler diagnostics—perfect when Gradle handles errors. It coexists with full LSPs for hybrid setups.

Who should use this?

Android engineers navigating massive multi-module projects who pair it with Gradle CI for type checks. Neovim or Helix users editing Kotlin without JVM overhead, or VS Code tinkerers seeking faster-than-IntelliJ navigation. Skip if you need rename/refactor or squiggles.

Verdict

Early alpha with 11 stars and 1.0% credibility—docs are solid, setup is straightforward, but expect rough edges like no incremental indexing. Try for low-memory kotlin lsp neovim wins in big repos; otherwise, stick to mature options.
