Decompile Electron 30 .jsc Files
Electron 30 runs on the V8 12.4 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. Electron 30 files sit on the V8 12.4 line, paired with Node.js 20.
No single magic is pinned for Electron 30. The decompiler reads the exact V8 version string from the file header instead. Not sure what you have? Analyze the header.

Upload at jscdecompiler.com

Auto-detect the version
JSC Decompiler reads the magic header and selects the V8 12.4 deserializer automatically — you never pick a version by hand.

Electron 30 version notes
- Electron 30 is built on Chromium 124 (the V8 12.4 line) and bundles Node.js 20.
- It sits on the same V8 12.4 line as Node 22's launch build, so their code caches share a bytecode format family.
- No dedicated magic is pinned for this build; the header's V8 version string drives detection on upload.
