What is claude-preview.nvim?

claude-preview.nvim is a Lua Neovim plugin that pops open a side-by-side diff preview of Claude Code CLI's proposed file edits right before you accept or reject them. It hooks into Claude's PreToolUse and PostToolUse events via RPC to your Neovim instance, using native diff mode for full-file reviews with syntax highlighting. Install via lazy.nvim or manual path in your neovim github config, then run :ClaudePreviewInstallHooks to wire it into .claude/settings.local.json.

Why is it gaining traction?

Unlike neovim github copilot chat or agent plugins that inline suggestions, this gives a dedicated tab or vsplit for scrutinizing full AI diffs—auto-equalized widths, custom highlights, and auto-close on accept prevent bad merges. Commands like :ClaudePreviewStatus and :checkhealth claude-preview make setup and troubleshooting dead simple, fitting right into neovim plugin manager workflows. It's a lightweight safety net for neovim github integration with AI tools, standing out in neovim plugins lists for Claude users.

Who should use this?

Neovim users running Claude Code CLI externally for file edits, like full-stack devs using neovim github copilot agent mode alternatives on large repos. Teams in neovim plugin tutorial flows experimenting with AI agents, or solo coders wanting previews before hitting 'y' in the terminal.

Verdict

Grab it for your neovim plugins if Claude Code is in your stack—excellent README and config guide make the 19 stars and 1.0% credibility score feel like early upside, not a red flag. Skip for production until more adoption, but perfect for side projects.
