Remote script. The install command pipes a script from GitHub straight into bash, so read install.sh first if you want to check what it does.

Credentials. The private link gives access to your photo library, so do not share it, and use --lan only on a network you trust.

Who it is forA person with a Linux or macOS computer holding a large photo archive who wants to edit it from a laptop, tablet or other device at home.

The problemPhotos sit on one machine, and editing them from other devices means copying files or paying for a cloud service.

The outcomeYour photos are edited in a browser through a private link served from the computer that holds them, with edits saved as XMP next to each photo.

What you need first

  • A computer running macOS, Windows or Linux with a photo folder you want to edit
  • A terminal for the Linux and self-host install commands
  • A GPU with WebGL 2 support is helpful; the README says older graphics cards are supported at reduced working size
  • Permission to open unsigned builds (System Settings › Privacy & Security › Open Anyway on macOS, More info › Run anyway on Windows)

Steps

  1. Open a terminal on the Linux or macOS computer that holds your photos.
  2. Run curl -fsSL https://raw.githubusercontent.com/thesnarkitecht/rembrandt/main/install.sh | bash -s -- --server
  3. When asked, choose the photo folder to use. The installer starts the server at login and prints a private link.
  4. Open the private link in a browser on the same computer, then run the same command with --lan added if you want other devices on your network to reach it.
  5. Make an edit, then check that an XMP file appeared next to the photo and that the original photo is unchanged.

Prompt for your agent

Using the repo thesnarkitecht/rembrandt, run the self-host install on <target-computer> with the --server option and report the private link it prints. Verify that the photo folder you chose still contains only its original photos and that any edit creates an XMP file beside the photo.

Caveat. The self-host server runs on Linux and macOS only, according to the README.
