Code Preview.Nvim

code-preview.nvim

A Neovim plugin that shows a **diff preview before your AI coding agent applies any file change** — letting you review exactly what's changing before accepting.

Supports [Claude Code](https://docs.anthropic.com/en/docs/claude-code) and [OpenCode](https://opencode.ai) as backends.
