Installation

Basilisk is a single Rust binary with no runtime dependencies — no Node.js, no Python interpreter, no package manager required after installation. For every supported editor, the binary comes with the extension; you never install it separately.

Pick your setup:

Editor support (LSP)

Basilisk implements the Language Server Protocol, so any LSP-capable editor can use it:

• VS Code — official extension, binary bundled → guide
• Cursor, Windsurf & other VS Code forks — via Open VSX → guide
• Zed — native extension, binary auto-downloaded → guide
• Neovim — official basilisk.nvim plugin, binary auto-downloaded → guide
• Helix — native LSP support (point it at a CLI install)
• Emacs — via eglot or lsp-mode (point it at a CLI install)
• JetBrains (IntelliJ / PyCharm) — coming soon

Integration status by editor

User estimates link to their sources and are the platforms' own published figures, not our measurements.

Next steps

Once installed, head to the Quick Start to run your first type check, or the Configuration reference to tune Basilisk in pyproject.toml.
