Helix
A post-modern modal editor — Rust-built, zero-config, and blazing fast in the terminal
About Helix
Helix is an open-source, terminal-based modal code editor written in Rust, inspired by Vim and Kakoune. It ships with built-in LSP support, Tree-sitter syntax highlighting, multiple selections, and intelligent auto-completion — all working out of the box with no plugins or configuration needed. Helix uses a selection-first editing model (select, then act) that's more discoverable than Vim's verb-first approach, and its Rust foundation delivers consistent performance across massive codebases. For developers who want a modern terminal editor without spending weeks configuring it, Helix is ready to use in under a minute.
Pros & Cons
Pros
- Zero configuration needed — LSP, Tree-sitter, and auto-completion work out of the box for 30+ languages without any setup
- Selection-first editing model is more discoverable than Vim — you see what you're operating on before executing an action
- Written in Rust for memory-safe, consistently fast performance with minimal resource usage
- Built-in features replace what would require 10+ plugins in Neovim — file picker, LSP, Tree-sitter, and diagnostics are all native
- Active open-source development with regular releases and a growing community
Cons
- No plugin system yet — you can't extend Helix beyond its built-in capabilities, which limits customization compared to Neovim or Vim
- Smaller community and ecosystem than Vim/Neovim — fewer tutorials, guides, and Stack Overflow answers available
- Terminal-only with a significant learning curve for developers coming from GUI editors
- No built-in terminal multiplexer or split terminal support — you'll need tmux or a terminal multiplexer alongside it
- Editing model differs from Vim — experienced Vim users face relearning muscle memory for the selection-first approach
Key Features
Selection-First Modal Editing
Kakoune-inspired editing model where you select text first, then apply actions — more visual and discoverable than Vim's verb-object-motion approach
Built-In LSP Support
Language Server Protocol integration out of the box — auto-completion, diagnostics, go-to-definition, and code actions work immediately for dozens of languages
Tree-Sitter Integration
Incremental parsing via Tree-sitter provides precise syntax highlighting, structural text objects, and syntax-aware selection expansion
Multiple Selections
First-class multiple cursor support with selection splitting, regex-based matching, and per-selection operations — no plugins needed
Zero Configuration
Works immediately after install with sensible defaults for every supported language — no init files, plugin managers, or hours of setup required
Built-In File Picker & Fuzzy Finder
Fast file navigation, buffer switching, symbol search, and global grep built directly into the editor
Rust Performance
Written entirely in Rust for memory safety and consistent performance — lightweight binary with minimal resource usage
Inline Diagnostics & Code Actions
LSP diagnostics shown inline with quick-fix code actions accessible from the editor — no separate terminal or panel needed
Pricing
- Full editor — free and open-source forever
- Built-in LSP for all supported languages
