Helix vs Huly Code

Helix is a free, terminal-based text editor for Linux, macOS, and Windows. Its editing model centers on multiple selections, so commands can act on several selections at once; it also supports multi-cursor editing and macro recording. Tree-sitter integration provides syntax highlighting, indentation calculation, and code navigation. Built-in language server support offers completion, go to definition, documentation, and diagnostics, though users need to install language servers for their chosen programming languages. Helix can select and navigate functions, classes, comments, and syntax tree nodes. Other included tools are a fuzzy finder for files and symbols, project-wide search, themes, automatic bracket pairing, and surround integration. Written in Rust, it can run in a terminal, over SSH, or in tmux. Configuration can be global or project-specific, including themes, keybindings, and language-specific settings; language servers and formatters can be configured through languages.toml files. Helix has no plugin system currently, although one is intended for the future. A graphical frontend is described as a future possibility.

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.
