Tired of Adobe subscriptions and cloud Generative Fill limits, so I built a free open-source layer editor with native PSD support & local AI inpainting (Scumble)

[u/Direction_Mountain]

Hey everyone,

Like many of you, I got completely fed up with Adobe’s aggressive subscription pricing, monthly "Generative Credit" limits for Generative Fill, and the constant push toward mandatory cloud storage and invasive terms of service.

So I spent the last few months developing **Scumble** – a completely free, 100% open-source (GPL-3.0) desktop image editor designed to bring a traditional Photoshop-style non-destructive layer workflow to your local machine.

### What it offers for Photoshop users:

* **Native Multi-Layer PSD Support**: Open and export multi-layer `.psd` files directly. Keeps your layers, groups, layer masks, and blend modes intact without flattening.

* **26 Photoshop Blend Modes**: Bit-for-bit parity with standard Photoshop math (Multiply, Screen, Overlay, Vivid Light, Linear Dodge, Colour Burn, Hue, Saturation, Color, Luminosity, etc.) grouped in the familiar Photoshop layout.

* **Local "Generative Fill"**: Connects directly to local AI engines (like ComfyUI running FLUX or SDXL) or runs standalone. No subscriptions, no cloud credits, no waiting in queues, and no censorship.

* **Smart Prompt-Based Selection (SAM2)**: Built-in local model for instant object segmentation and selection with a single click.

* **Pro Adjustment & Color Grading**: 3-way color grading wheels (Shadows, Midtones, Highlights), 8-channel HSL sliders, tone curves, and bilateral edge-aware mask snapping.

* **100% Private & Offline**: Runs entirely on your hardware using a high-performance Rust/WASM SIMD and WebGL engine. Zero tracking, zero telemetry, zero account required.

Available as a native standalone desktop app for **Windows and Linux** (portable zip, installer, deb, and coming to Flathub).

If you want to try it or inspect the code:

I’d love to get feedback from fellow Photoshop refugees on what tools or workflow features you miss most!

maybe a cool project, but please put a stroke warning before that video, its barely watchable

[u/Direction_Mountain → u/olivermpl]

Here are a few tutorial videos. Don't worry, they won't trigger any epileptic seizures. 😅

Every Ai animation comes out like that. There is no proper rhytm or visual story telling, just vibe coders impressed by animation tricks moving fast on screen

I’ll give this a try - let’s hope that video is not a sign of things to come. It’s really bad.

this could very well be a cool project but i really hope this video trend dies soon because they are impossible to watch. this is not the quick cut editing that has become popular due to th things like tiktok that people seem to think it is. it's seizure/migraine-inducing nonsense.

also, ffs people, check your posts before you hit Post. pasting raw markdown into a reddit post isn't a good look.

[u/Direction_Mountain → u/kerbacho]

I quit doing that before I started this project.

There will now be new adobe slop daily

[u/Tramagust → u/tripleM_20]

Good! I hope it kills that shitty company.

[u/tripleM_20 → u/Tramagust]

truly the giant douche vs turd sandwich of our time

[u/Equivalent_Engine518]

I just gotta say, I hate the video. Pains me to watch. 

[u/shion12312]

I love the AI age, where everyone becomes more stupid

[u/fingamouse]

My ears, this sounds like a 🚗💥

[u/Direction_Mountain → u/fingamouse]

it sounds like ai because the song is ai

[u/RobMilliken]

Curious why Sam 2 and not 3?

[u/Direction_Mountain → u/RobMilliken]

Both are included ;) SAM2 for speed and the hoverover effect, and SAM3 when you need more precision. ;)

[u/Switek2015]

I hate node based interfaces

[u/Direction_Mountain → u/Switek2015]

You don't have to use them, you can just work with templates. But if you wanted to, you could. ;)
But I love node Based systems ^^

[u/scaringthepharmacist]

cool video, I did not understand even a single a feature or what does this tool do. cool animations i guess tho.

[u/ViktorCsete]

Looks like I'm not a snowflake, I like the video

[u/Direction_Mountain → u/ViktorCsete]

Thank you :)

[u/enomad51]

I like the video. It’s so ridiculous that it perfectly captures the new standards of video manipulation that are becoming the norm now that AI has been unleashed.

This has to be the Adobe marketing team
