# Reverse Engineer Anything (REA) 解析

一篇關於 REA 的簡短解析，這是一個 MIT 授權的附加元件，可接入 Claude Code、Codex 或 Cursor：一條 npx 設定命令、反編譯器整合（Ghidra、Hopper、IDA）、針對網站的瀏覽器錄製，以及直接讀取 Electron 應用程式的 JavaScript，並以 REA 的 Notion 和 DX-Ball 展示為例，外加成本、限制以及免責聲明——其輸出不授予你對原始程式的任何權利。

## Description

Reverse Engineer Anything (REA) 是一個免費、MIT 授權的附加元件，可讓 Claude Code、Codex 或 Cursor 查看你未撰寫的應用程式內部。這是它在真實目標上返回的內容、花費多少以及在哪裡停止，五分鐘內講完。

影片涵蓋 morluto/rea 儲存庫：一條 npx 命令即可將 REA 接入你的代理，針對編譯應用程式的反編譯器（Ghidra、Hopper 或 IDA），針對網站的瀏覽器錄製，以及直接讀取 Notion 等 Electron 應用程式內部的 JavaScript。逐步演示了兩個 REA 展示：追蹤 Notion 的剪貼簿路徑，以及重建一個 DX-Ball 聲音聲像函式，該函式通過了 3,205 個測試案例並與全部 63 個編譯位元組匹配。它還涵蓋工具定價、第三方測試中的輸出大小、伺服器端限制，以及 REA 的免責聲明——其輸出不授予你對原始程式的任何權利。來源包括 REA 儲存庫、其 Notion 和 DX-Ball 展示以及免責聲明。

## Original README

Reverse Engineer Anything (REA) Explained

Reverse Engineer Anything (REA) is a free, MIT-licensed add-on that lets Claude Code, Codex or Cursor look inside apps you didn't write. This is what it returns on a real target, what it costs and where it stops, in under five minutes.

The morluto/rea repo got single-digit stars a day through September, then picked up just over 50,000 GitHub stars on October 12 and is past 200,000 now. The jump followed posts by Replit CEO Amjad Masad and Matthew Berman ("Software is done.", about 3.5 million views). The video covers what is actually in the repo: one npx command that plugs REA into your agent, a decompiler (Ghidra, Hopper or IDA) for compiled apps, browser recording for websites, and direct reading of the JavaScript inside Electron apps like Notion.

Two of REA's own showcases are walked through. On Notion, the agent traces how text and HTML reach the clipboard, from the page through the notion:clipboard:write channel to the main process. On DX-Ball, a 1996 Windows game, the rebuilt sound-pan function passes 3,205 test cases against the original and matches all 63 compiled bytes, though the game isn't playable yet.

REA and Ghidra are free. Hopper starts at 99 euros and IDA Pro at 1,099 euros a year. REA publishes no typical token cost; it runs on your agent's plan, and in Kingy AI's test a 1,648-byte example produced about 907 KB of output. Server-side logic stays out of reach, and REA's disclaimer says its output gives you no rights to the original program. What you get is a map of one feature that keeps what the agent saw, what it inferred and what it still doesn't know apart.

Questions this video answers:
- What is Reverse Engineer Anything (REA)?
- Why did REA get over 200,000 GitHub stars?
- Does REA work with Claude Code and Codex?
- What does REA return when you point it at an app?
- How much does REA cost, and do you need to pay for IDA or Hopper?
- Can REA make a copy of an app you pay for?

I didn't run REA myself for this video. The Notion and DX-Ball results are REA's own showcases, the CSV and output-size numbers are Kingy AI's test, and the Preview rebuild is MindStudio's informal write-up. Star counts are from GitHub and Trendshift on October 14, 2026.
