Wands out, nostalgia up
GrobPaint: Somewhere Between MS Paint and Paint.net. Multiplatform by Default
Mac finally gets a Paint-like app — fans cheer, nitpick, and get nostalgic
TLDR: GrobPaint is a lightweight, cross‑platform image editor filling the Mac gap left by Paint.NET. Comments swung between asking for a Magic Wand (it’s already included) and warm HP 48G nostalgia over the name, underscoring demand for simple, no‑bloat tools that just work across devices.
GrobPaint dropped like a tiny art bomb: a fast, simple image editor that feels snappier than MS Paint but not as complicated as Photoshop. It works on Mac, Windows, and Linux, filling the Paint.NET-on-macOS hole with layers, blend modes, and the tools people actually use. The mood? “No bloat, just create” energy — with a side of feature FOMO and retro fanfare.
Top comment drama: one fan begged for a Magic Wand color-select tool, pointing to Paint.NET’s version. Plot twist — GrobPaint already has Magic Wand baked in, complete with adjustable tolerance. Cue knowing chuckles as the feature list quietly flexes. Meanwhile, another commenter turned the thread into a wholesome nostalgia tangent, cheering the name “GrobPaint” because old HP 48G calculator graphics were called “GROBs.” Suddenly we’re swapping pixel memories while testing blend modes — peak internet energy.
Under the hood gossip added spice: it’s built with simple web tech and a tiny Python launcher, and the project even credits help from Claude (an AI by Anthropic) — a wink that had readers curious about how much bots are helping build our tools now. Between the retro shout-outs and the feature wish-listing, the community vibe is clear: keep it light, keep it fast, and yes, keep that Magic Wand within reach.
Key Points
- •GrobPaint is a lightweight, cross-platform image editor positioned between MS Paint and Paint.NET, with layers, blend modes, and selection tools.
- •It runs via a minimal Python backend with a web-based frontend, launching in a native window through pywebview or falling back to the browser.
- •Project files use a .gbp format, a ZIP archive containing a manifest and per-layer PNGs; standard formats (PNG, JPEG, BMP, GIF) are supported.
- •A build script uses PyInstaller to create standalone apps (GrobPaint.app for macOS and a binary for other platforms).
- •The codebase (~2,500 lines of vanilla JS) is organized into modules for core logic, rendering, tools (including flood fill/select), UI, and app initialization, with JSZip as the only external browser-side dependency.
