Robbie Tilton got tired of paying for Photoshop and built Compositor, a free, open-source Mac image editor focused on compositing and post-processing workflows, releasing the full Xcode project so anyone can modify it.
- The entire app is 12MB, versus 6,455MB for Photoshop on the same machine
- Ships pro compositing tools: layers/folders, masks, clipping masks, blend modes, selections, adjustment layers, filters, background removal, liquify, spot healing, clone stamp
- The author admits the workflow feels old-school: AI still can't nail pixel-perfect manual compositing, so he built the tool he actually needed
