Decompile Node.js 20 .jsc Files
Node.js 20 runs on the V8 11.3 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 20 files sit on the V8 11.3 line, paired with Electron 23–27 (V8 11.x).

Upload at jscdecompiler.com
Drag and drop your Node.js 20 .jsc file into the web app. Nothing to install.
Auto-detect the version
JSC Decompiler reads the magic header and selects the V8 11.3 deserializer automatically — you never pick a version by hand.

Node.js 20 version notes
- Node 20 launched on V8 11.3 and carries the 0xC0DE05F2 magic; it shares the V8 11.x line with Node 21 and Electron 23–27.
- V8 11.x introduced the Maglev mid-tier compiler groundwork, though the code cache still stores Ignition bytecode.
- Node 20 is an active LTS, so fresh bytenode bundles are common — the decompiler tracks new 11.x minors as they ship.
