2026.2Starfield, namespaces and a setup wizard

Compile Papyrus without opening the Creation Kit

PCA is a Windows app for Skyrim SE, AE, LE, VR, Fallout 4 and Starfield. Drop your .psc files in and press Start — the imports, the flag file, the namespace and the output folder are worked out for you.

  • Free and open source
  • Windows
  • No account, no plugin to load

One app, five games

A single PCA.exe compiles for all of them. The game is a setting, changed whenever you want.

Everything the command line makes hard

PCA is a front end for PapyrusCompiler.exe, the compiler the Creation Kit ships. It does the parts you would otherwise type out every time.

  • Set up in four steps

    A wizard runs on first launch: pick your game, point at its folder, and PCA finds the compiler on its own.

  • Creation Kit report

    A missing kit, an unextracted archive, sources in the wrong folder — PCA names the problem, and most of the time offers the button that fixes it.

  • Drop, then Start

    Drag your .psc files in and press Start. Imports, flag file and output folder are worked out for you, 15 scripts at a time.

  • Groups and recent files

    The scripts you compile all day, saved under a name and loaded in one click. The last 30 are kept whether you save them or not.

  • Papyrus namespaces

    Fallout 4 and Starfield keep their scripts in folders. PCA compiles them where they belong, and writes the .pex back in place.

  • Nothing personal shipped

    The compiler stamps your user name, computer name and full path into every .pex. PCA strips them before you upload the mod.
