Scumble is a free, open-source desktop editor for AI inpainting. Select part of a picture, say what belongs there, and the result lands as its own colour-matched layer. Runs on your own ComfyUI or your own API keys: FLUX 3, GPT Image, Nano Banana and more.
Hey Product Hunt 👋 I'm Dennis, and Scumble started as a weekend project.
I do a lot of inpainting, and I kept doing the same dance: build a mask here, run a workflow there, pull everything back into an image editor, fix the edges, repeat. So I built an editor made for exactly that.
What it does:
🎯 Select by painting, by pointing at an object, or by typing what it is
🧱 Every result comes back as its own layer, colour-matched to its surroundings. Your original is never touched
✂️ Through an API, only the area around your selection leaves your machine, and the answer comes back at full resolution
📦 Boxes in the prompt: draw where things go and describe each box (FLUX 3 Image, Ideogram 4)
🖼️ Reference images by name: "put their cup from @img1 on the sill"
🔌 Your own ComfyUI (local, remote or Comfy Cloud) or your own keys for FLUX 3, FLUX.2, GPT Image, Nano Banana, Seedream, Qwen, Ideogram and more
🤖 An MCP server with 105 tools, so Claude Code or any other MCP client can drive the editor
🎞️ 46 film looks as layers, retouch tools, PSD / ORA / TIFF export, and pictures of 15,000 pixels and more
It's free and open source (GPL-3.0). No account, no telemetry, and your API keys stay in the system's credential store. You pay the providers directly; Scumble takes no cut.
Honest status: it's version 0.1.x and moving fast. Windows comes first: it's in the Microsoft Store (signed by Microsoft), and there's a GitHub installer and a portable zip. Linux builds come out of CI, but I haven't run them myself yet. Mac is planned. Not every API provider has been tested live.

One question for you: what's the most annoying step in your inpainting workflow today?
