  • From the README
  • Any agent

Who it is forA developer on Windows x64 who wants to build the fingerprint kernel locally instead of using the bundled one.

The problemThe release kernel is prebuilt, but a developer who needs to audit or change it has to build the pinned source tree.

The outcomeA local Chromium build with Chromedriver, installer artifacts, a build manifest, and SHA-256 checksums, which can be imported into the app.

What you need first

  • A Windows or macOS computer
  • The latest package from the project's Releases page
  • For the kernel build only: Node.js 22 or later, npm, Git, Python 3, Visual Studio with C++ tools on Windows, or Xcode on macOS, about 300 GB free SSD space, and 32 GB RAM

Steps

  1. Open a non-administrator PowerShell session in the repository, then run Set-ExecutionPolicy -Scope Process Bypass.
  2. Install npm ci dependencies from the repository root, then run cd tools\windows-kernel.
  3. Run .\Check-Prerequisites.ps1 -BuildRoot D:\prism-chromium and follow any long-path instructions it gives, then restart Windows if asked.
  4. Run .\Prepare-Source.ps1 -BuildRoot D:\prism-chromium to download the pinned source tree, which is large.
  5. Run .\Build-Kernel.ps1 -BuildRoot D:\prism-chromium -Jobs 4 and rerun it after any interruption to resume.
  6. Open the Browser Kernels page in Prism Browser, select Import Local Build, choose the directory containing chrome.exe, then verify and activate the kernel.

Prompt for your agent

Using the repo DFarm6/Prism-Browser-Community, check the Windows kernel prerequisites in tools/windows-kernel/README.md for a build root of <build root path>. Expected output: a list of required tools that are missing. Verify the build root is a short NTFS path before running the build scripts.

Caveat. The first build downloads the complete source tree and toolchain and the README recommends 32 GB of RAM and about 300 GB of free SSD space.
