Decompile Electron 27 .jsc Files
Electron 27 runs on the V8 11.8 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 27 files sit on the V8 11.8 line, paired with Node.js 18.

Upload at jscdecompiler.com
Drag and drop your Electron 27 .jsc file into the web app. Nothing to install.
Auto-detect the version
JSC Decompiler reads the magic header and selects the V8 11.8 deserializer automatically — you never pick a version by hand.

Electron 27 version notes
- Electron 27 spans the V8 11.6–11.8 line (Chromium 118) and bundles Node.js 18; 0xC0DE05EC marks a 27.0 build and 0xC0DE05F8 a later 27.3.x build.
- It closes the V8 11.x Electron line before Electron 28 moves to V8 12.x.
- Pointer compression is on, so the code-cache pointer width differs from a stock Node 18 build.

Electron 27.0 and 27.3.x shipped slightly different V8 11.x builds. Each .jsc records the build that wrote it.
