zerodiffa declaration
Compiled code is a locked room.
Studios close. Toolchains rot. Repos vanish in a move.
The binary survives, and everything that made it is still in there.
We get it back out.
If you own the software, you should be able to read it, fix it and port it. ZeroDiff turns that into a job you can order.
zero diff
fig. i — the first survey7 of 8 functions. Byte-identical. Blind.
We gave an AI agent the raw disassembly of eight arm64 functions. No source, no hints. Seven came back as C that compiles to the exact same bytes as the original, on the first try.
| function | rebuilt / original | status | evidence |
|---|---|---|---|
| sum64 | 156 / 156 B | byte-exact | NEON loop, 39 insns |
| binary_search | 68 / 68 B | byte-exact | 17 insns |
| fnv1a | 48 / 48 B | byte-exact | 12 insns |
| count_ones | 36 / 36 B | byte-exact | 9 insns |
| gcd | 32 / 32 B | byte-exact | 8 insns |
| clamp_s32 | 20 / 20 B | byte-exact | 5 insns |
| rotl32 | 20 / 20 B | byte-exact | 5 insns |
| insertion_sort | 104 / 112 B | parity-red | builds, 3-round budget |
Nothing ships as "trust me". Every function is graded.
Identical bytes to the original, same compiler, same flags. Zero diff.
Builds and passes an independent checker and the build and test gates.
Builds, with every gap listed.
Builds, with the instruction diff attached.

owners of the shipYour game
Running on the hardware you actually play on. Port it, mod it, keep it alive.
Your lost source
The repo is gone. The binary isn't. Get the code back.
Your firmware
The toolchain died. Your devices didn't. Rebuild it on today's tools.
Your research
See exactly how it works, down to the instruction, in software you have the right to study.
how it works
the route- 01
Drop the binary
Upload it with a rights statement that says it is yours to open.
- 02
Lock the price
You get a quote first and set a hard cap. The agents stop at it.
- 03
Agents go to work
Decompilers take the easy functions. Agents take the rest. Every one is recompiled and diffed against the original bytes.
- 04
Take the source
C, disassembly, call graph, and a grade on every function. Yours to build, ship and keep.
pay onchain
No card, no invoice, no sales call. Fund the job from your wallet and watch it run.

articles of the crew- Your binary, your source. You own it or have the right to analyse it. That is the only way in.
- Inputs are wiped on a short clock. We keep nothing we weren't asked to keep.
- We respect the decomp community. No agent patches pushed into community projects.
