Nebuloom

Nebuloom is a local-first wallpaper studio for abstract backgrounds built from gradients, shapes, grain, curated presets, and reproducible seeds. The idea is simple: start with a visual recipe, tune the palette, format, seed, and composition controls, then export a clean wallpaper without anything leaving the browser.

The repository is structured as a small workspace. The runnable SvelteKit application lives in apps/web, while packages/wallpaper-engine holds the UI-free engine code for preset definitions, palette and format data, deterministic scene generation, canvas rendering, and raster export helpers.

I started Nebuloom as a learning project for Svelte and SvelteKit, but it also became a practical product-design exercise: studio UX, preset taxonomy, identity, light and dark palettes, local persistence, export controls, and a clean deployment setup on Vercel. It was also a good test bed for working with Codex and Claude Code on real product code rather than isolated examples.
