What is grobpaint?

Grobpaint is a lightweight image editor positioned somewhere between MS Paint and Paint.NET, filling the gap for macOS and Linux users missing Paint.NET's features. Built in JavaScript with a minimal Python backend, it delivers layers, 16 blend modes, selection tools (rect, wand, lasso), adjustments like brightness/contrast and gaussian blur, plus sprite sheet import/export—all multiplatform by default via pywebview or browser. Launch with `python grobpaint.py` for a native window, or install as a PWA for offline use; supports PNG/JPEG/BMP/GIF and .gbp project files with auto-save to localStorage.

Why is it gaining traction?

No frameworks, no bundlers—just 2500 lines of vanilla JS for snappy performance across Windows/Linux/macOS, with PWA perks like clipboard paste and multi-tab docs. Standout hooks include live previews on adjustments, pixel-perfect tools with anti-aliasing toggles, and sprite workflows like splitting sheets into layers, appealing to devs ditching bloated apps like GIMP for quick edits. Its "somewhere between" simplicity avoids Photoshop bloat while packing pro tools like opacity/blends and rotatable selections.

Who should use this?

Pixel artists crafting sprite sheets or UI mockups, indie game devs needing fast layer compositing without installs, and frontend engineers tweaking assets cross-platform. Ideal for macOS users wanting Paint.NET vibes for casual edits like resizing/cropping with nearest-neighbor scaling, or anyone prototyping between heaven and hell in browser tabs.

Verdict

Grab it for lightweight, multiplatform pixel editing if you need layers and selections without the overhead—impressive vanilla JS craft shines despite 46 stars and 1.0% credibility score signaling early maturity. Solid docs and zero deps make it a fun daily driver, but wait for more tests if production-critical.
