Decompile Node.js 23 .jsc Files
Node.js 23 runs on the V8 12.9 line. JSC Decompiler reads the V8 build straight from the bytecode header and turns compiled .jsc files back into readable JavaScript — no matching runtime required.
Bytecode fingerprint
Every .jsc file opens with a 4-byte little-endian magic header that identifies the V8 code-cache format. Node.js 23 files sit on the V8 12.9 line, paired with Electron 28–32 (V8 12.x).

Auto-detect the version
JSC Decompiler reads the magic header and selects the V8 12.9 deserializer automatically — you never pick a version by hand.

Node.js 23 version notes
- Node 23 shipped the V8 12.9 line and carries the 0xC0DE0656 magic; it is the 'current' bridge release between the Node 22 and Node 24 LTS lines.
- V8 12.9 sits on the same major as Node 22's launch V8 (12.4), so the two share a bytecode format family disambiguated by the header.
- Node 23 files are relatively rare given the short 'current' window before Node 24.
