Huly Code vs Lapce

Huly Code is a free, open-source integrated development environment based on IntelliJ IDEA Community Edition. It includes code navigation, completion, and analysis, and works with modern Language Servers, including Rust Analyzer. Tree-sitter supports syntax highlighting and code analysis. For plugins, Huly Code uses open-source software rather than proprietary JetBrains plugins. Huly says it is developing the IDE to examine efficient collaboration between humans and AI agents in software development. The README describes optional integration with Huly Platform as a future capability, rather than a current feature. The project is described as open-source and free to use, with a listed Free plan at free. The repository links to a security policy. Its specified coding tools and language-server support give developers core navigation, completion, and analysis capabilities in an IDE built on the Community Edition foundation. Those interested in the stated human-and-AI collaboration focus may also want to follow the project, while treating Huly Platform integration as a future possibility.

Lapce is an open-source code editor written in Rust, available for Linux, macOS, and Windows. It uses a native graphical interface with GPU acceleration through Floem. For code intelligence, it combines Tree-sitter syntax highlighting with Language Server Protocol support for completion, diagnostics, and code actions. Developers can connect to a remote machine to work in an environment matching a production server, and the included terminal opens at the workspace path. The editor has built-in Vim-like modal editing and supports multiple cursors. Plugins can be written in any programming language that compiles to WASI, and the editor supports extensions. Downloads include Linux tar.gz builds for x86 and ARM, Windows system installer and portable x86 builds, and a universal macOS DMG. The product page displays version 0.4.2. Its documentation covers setup, settings, keybindings, modal editing, remote development, themes, terminal use, multiple cursors, syntax highlighting, and plugin development. The About page says Lapdev is maintained by the Lapce team and describes Lapce and Floem as open-source projects.
