rea
See how any app feature works inside.
Watch the reel
rea is an open source reverse-engineering toolkit that points a coding agent at any app and learns how it works, from app behaviour down to native binaries.
It inspects native binaries through Hopper or Ghidra, JavaScript and Electron apps, .NET assemblies and websites, and explains how a feature works with the evidence and limits behind each conclusion. Version 6.8.0, MIT licensed.
Key facts
- Reverse-engineering toolkit for coding agents

How to use it
- rea install karo aur apne coding agent se connect karo.
- Kisi app ya feature ko point karo.
- Agent batayega ke feature kaise kaam karta hai — evidence aur limits ke saath.
Pros and cons
Pros
- Kisi bhi app feature ka andar se pata chalta hai.
- Har conclusion ke peeche evidence aur limits likhe hote hain.
- Free, open source, local chalta hai.
Cons
- Deep native work ke liye alag analysis engine chahiye.
- PikyAI ne live test nahi kiya.
Alternative
- Manual reverse engineering — Hopper ya Ghidra haath se chalana bhi mumkin hai, bas agent ki explanation aur evidence ka flow nahi milta.
How this rank works
Directory rank is set by bid, not by editorial opinion. New listings start at $5, a higher bid outranks a lower one, and taking #1 costs at least $5 more than the current top bid. Paid ranks always carry a Sponsored label, and payments are final and non-refundable. This listing sits at the $5 floor as a PikyAI house listing, not a paid rank.
