Reviewer：面向 macOS 的代码审查工具，支持 Claude Code 与 Codex

Reviewer showing a side-by-side diff of uncommitted changes, with the changed files beside it

Features

A diff viewer that reads the way you do

Lay the diff out side by side or top to bottom, whichever reads better for the change in front of you. Click any file to open it on its own and read it whole.

Work with Claude Code and Codex from the same interface

Use popular harnesses directly in Reviewer, or use skills to connect to any harness you have on your machine.

Picking the model for an agent chat, with Claude and Codex models side by side

Comment, then hand it off

Leave a comment on any line, then assign it to an agent to pick up and fix.

Run your services in one click

Set up your local services once from a macOS widget and start them with a single click. If it runs in a terminal, it runs here.

Intuitive Git integration

Create new branches and let Reviewer write the commit message from what changed.

Know what changed, and when

Filter the history by author, date or branch. Click any entry to see what changed and when, or open a single file's history to follow how it got to where it is.

Follow a code symbol to its source

Language server protocol integration for TypeScript, Swift, Ruby and PHP. Hover a symbol for its signature and docs, or find every usage of it across the codebase. In a Laravel app, view(), config(), env(), __(), Blade includes and <x-…> components link to the files they name, and PHPStan's findings show beside the language server's when the app runs it. No PHP server installed? Settings → Languages installs intelephense for you.

And the rest

Terminal — A built-in terminal for ad hoc work, right next to the code.
Light and dark — Follows your Mac, or pick the appearance you prefer.
Themes — Shiki and Pierre themes to make the environment your own.
Native to the Mac — Built for Apple silicon, macOS 26 and later.

Install

Download the latest Reviewer-<version>-arm64.dmg from Releases (or from reviewer.sh).
Open the disk image and drag Reviewer into Applications.

Requirements: an Apple silicon Mac on macOS 26 or later.

Every release is signed with a Developer ID and notarized by Apple. Reviewer keeps itself up to date: new versions are offered in-app as they ship.

Resolve review comments with any agent

Comments you leave in Reviewer can be handed to any coding agent (Claude Code, Codex, Cursor, OpenCode, …) through the resolve-reviewer-comments skill. It reads the repository's comments from Reviewer's local API server, implements them and resolves them one by one.

npx skills add Darna-Digital/reviewer --skill resolve-reviewer-comments

Then, with Reviewer running, ask the agent to "resolve my reviewer comments".

Development

Reviewer is a pnpm monorepo: a native SwiftUI/AppKit shell that hosts parts of a React web app as views inside its own layout, beside a local API server that does the git and filesystem work.

Package	What it is
`packages/mac-os`	The macOS app — a Swift package (SwiftUI + AppKit), bundled into `Reviewer.app`
`packages/spa`	The React web app whose surfaces the shell hosts
`packages/embedded-server`	The local API server the app runs beside it (Effect, git/filesystem-backed)
`packages/core`	Feature schemas and services shared by the server and the SPA
`packages/tui`	Reviewer in a terminal — diffs, branches, history and comments (OpenTUI, Bun)
`packages/www`	reviewer.sh, on Cloudflare Workers
`packages/brand`	The brand studio that draws and exports the logo and icons
`packages/lint`	Shared ESLint and Prettier config

Prerequisites

macOS 26 on Apple silicon, with Xcode 26
Xcode's Metal toolchain: xcodebuild -downloadComponent MetalToolchain
Node.js (current LTS) and pnpm 11 (corepack enable)
Bun 1.3+, for the terminal UI only

Run it locally

pnpm install
pnpm dev      # API server + SPA, in one terminal
pnpm dev:mac  # build and open the debug app, in another

Command	Does
`pnpm dev`	API server + SPA in watch mode
`pnpm dev:mac`	Build and open the debug `Reviewer.app`
`pnpm dev:www`	The reviewer.sh site
`pnpm tui`	The terminal UI, on the repository you are in
`pnpm install:tui`	Build the terminal UI and install `reviewer`
`pnpm build:mac`	A release build of `Reviewer.app`, as CI builds it
`pnpm lint`	ESLint across the workspace
`pnpm format:check`	Prettier across the workspace
`pnpm typecheck`	TypeScript across the workspace
