为什么值得关注

它提供了原生的、键盘驱动的代码审查体验，包括统一/分屏视图、词级差异和直接提交 GitHub 审查，全部集成在一个轻量级 Rust 应用中。

适合谁使用

探索 gpui 原生 GUI 的 Rust 开发者
经常审查 GitHub 拉取请求的 macOS 用户
希望获得快速、键盘为中心的浏览器替代方案的开发者

典型使用场景

在 GitHub 拉取请求中进行内联评论和审批
比较本地 git 差异，包含词级变化
通过缩略图和模糊文件过滤器在代码审查中快速导航大型代码库

项目优势

在 Apple Silicon 上具有原生性能，依赖少
丰富的差异功能：统一/分屏视图、词级行内差异、缩略图
深度 GitHub 集成：PR 选择器、内联评论读写、审查提交
以键盘为主的设计，提供大量快捷键以实现快速导航

使用前须知

仅支持 macOS 且需要 Apple Silicon（不支持 Intel 或 Linux）
应用未签名，首次启动需要手动覆盖或移除法务隔离
作者声称未审查代码（vibe coded），可能影响可靠性和可维护性

README 快速开始

lgtm

A fast, native code-review app in Rust, built with gpui.

Requires the GitHub CLI (gh auth login first), otherwise you can only review code locally.

This is 100% vibe coded. I have not read the code.

Setup

Grab LGTM.dmg from the latest release (built from every commit on main, Apple Silicon only), open it, and drag LGTM to Applications.

The app is unsigned, so on first launch macOS will complain — right-click the app and choose Open, or:

xattr -d com.apple.quarantine /Applications/LGTM.app

Or build from source:

cargo run --release

Note that you will need Xcode to build it from source because the metal dev tools are bundled with it. Otherwise the build fails with the following error:

cargo:rerun-if-changed=./src/platform/mac/shaders.metal
cargo::error=metal shader compilation failed:
xcrun: error: unable to find utility "metal", not a developer tool or in PATH

Features

unified + split views
tree-sitter highlighting (18 languages),
word-level intra-line diffs,
multi-item sidebar with file tree
cmd-k palette with fuzzy PR picker,
local repo diffs
minimap,
inline GitHub review comments (reading + posting, hover a line for +)
submitting reviews (approve / request changes / comment, cmd-enter or the Review button)

Coming: LSP, AI inline review annotations

Keymap

Key	Action

`r`	refresh active item
`cmd-enter`	submit review (approve / request changes / comment)
`home` / `end`	top / bottom
