# PeerBrush on Ubuntu: painting and layered PSD editing on a shared canvas > Source: > Published: 2026-11-08 13:14:38+00:00 [Ilai_Perez](https://linuxcommunity.io/u/Ilai_Perez) (Ilai Perez) 1 I’m affiliated with PeerBrush. The project summary below was drafted with AI assistance using the released documentation. PeerBrush is a GPLv3 desktop image editor for painting and working with layers and masks. Version 0.30.1 has a DEB for Ubuntu 24.04 amd64. You can paint in the editor normally, or connect a compatible local MCP client to work in the same document. Separate layers can be reserved so an automated edit does not overlap your work. PeerBrush edits and saves supported 8-bit and 16-bit RGB layered PSDs. Files with unsupported Photoshop structures open as read-only previews. [Source code](https://github.com/Deftr0y/PeerBrush) · [Ubuntu DEB and SHA-256 checksums](https://github.com/Deftr0y/PeerBrush/releases/tag/v0.30.1) · [63-second demo](https://peerbrush.com/#demo) If you try the Ubuntu build, feedback on brush responsiveness and reopening a saved layered file would help. Please include your Ubuntu version and GPU if you run into a rendering issue. The workspace screenshot uses example artwork made with ImageGen. PeerBrush is developed with AI assistance. 5 Likes [hydn](https://linuxcommunity.io/u/hydn) (Hayden James) 2 Welcome to the community [@Ilai_Perez](https://linuxcommunity.io/u/ilai_perez) and thanks for being upfront about your affiliation. What’s your role on PeerBrush, and is it a solo project or is there a team behind it? Also curious what led to the shared canvas and MCP approach, and who you see using it? For someone already painting in Krita or GIMP, where does PeerBrush fit? Any plans for a Flatpak or packages for other distros? 4 Likes [Bombilla](https://linuxcommunity.io/u/Bombilla) (John) 3 Welcome to our community!
