Atlanta developer Brandon Thomas has released open-source counterparts to Photoshop, Premiere, Lightroom and After Effects. They run on macOS, and the PhotoCraft project exposes a command registry that can be driven through a graphical interface, CLI, JSON or MCP server. That makes the software interesting as an AI-controlled creative workflow, not just as a way to avoid a subscription.
There is an important caveat: the author calls PhotoCraft early alpha. Independent testers have found significant bugs and incomplete functionality. Do not trust a production PSD or client deliverable to it. The interesting question is whether a model can reliably automate a tiny creative task with a tool that exposes every operation programmatically.
Action: inspect the GitHub repository and the MCP interface. If you test it, use a disposable layered PSD in a separate folder. Compare the result with Photoshop rather than assuming parity.
