REA (Reverse Engineer Anything)
From 30k stars to 120k+ in three days, adding over 25k in a single day. MIT open source.
Everyone is talking about it, "everything software can be reversed,"
What I find more interesting is: tearing down hardware communication protocols.
The air conditioner, water heater, and lights at home all come with a hard-to-use vendor app. Behind the app is essentially a device communication protocol.
REA's recent updates have just completed this chain:
· Connect to an emulator or real device via adb, capture the official app
· Analyze HAR or mitmproxy captures, locate each request to the app source code
· Use Binwalk/Unblob to unpack firmware, then hand it to Ghidra for analysis
Then hand the evidence to Claude Code / Codex, reverse the protocol, and write your own control client.
Someone on X has already used the same approach to reverse an air conditioner, made it into a Mac status bar app, and then spent 15 minutes porting it to AR glasses, so you can control it with a glance.
Previously, vendor apps decided how you could use your own devices; in the future, you can write your own.

REA（Reverse Engineer Anything）逆向一切
三天从 3 万 Star 涨到 12 万+，一天新增 2.5 万以上。MIT 开源。
大家都在说它，"一切软件都可逆"，
我看到更好玩的是：拆硬件的通信协议。
家里的空调、热水器、灯，基本都配了一个难用的厂商 App。App 背后，其实就是一套设备通信协议。
REA 这几天的更新正好补齐了这条链路：
· adb 连模拟器或真机，抓到官方 App
· 分析 HAR 或 mitmproxy 抓包，把每个请求定位到 App 源码
· 用 Binwalk/Unblob 拆固件，再交给 Ghidra 分析
然后把证据交给 Claude Code / Codex，还原协议，自己写控制端。
X 上已经有人用同样的思路，逆向了空调，做成 Mac 状态栏应用，又花 15 分钟移植到 AR 眼镜上，看一眼就能控制。
以前是厂商 App 决定你能怎么用自己的设备，以后你可以自己写。
