| Fact | IntelliJ IDEA | Lapce |
|---|---|---|
| Code intelligence | The IDE provides context-aware navigation, inspections, refactorings and debugging across a project. | Lapce includes Tree-sitter syntax highlighting and LSP support for completion, diagnostics, and code actions. |
| Documentation depth | JetBrains publishes installation, security, update, Docker, Kubernetes and extensive plugin-SDK documentation, with source documentation hosted on GitHub. | The GitBook documentation covers setup, workspaces, remote SSH, terminal profiles, keybindings, syntax grammars, architecture and plugin publication, but its introduction page says it was last updated a year ago. |
| Product | IntelliJ IDEA is an IDE for professional development in Java and Kotlin. | Lapce is an open source code editor written in Rust. |
IntelliJ IDEA suits developers working in Java or Kotlin who want an IDE with debugging, build-tool, and version-control integrations. Its free core is an option for those who do not need Ultimate's advanced tools and integrations.
Lapce suits developers looking for an open-source editor on Linux, macOS, or Windows. Its remote development, Vim-like editing, and WASI-compatible plugins may be useful to people who want those workflows.
