Rennu is a free tool for creating atmospheric, textured gradients inspired by Japanese art and design. Pick from curated presets or build your own from scratch — adjust colors, blur, texture, and direction until it feels right. No login, no watermark, no paywall. Export as PNG or JPG at any resolution — ready for backgrounds, wallpapers, UI screens, or brand assets. Built for designers who want that soft, textured, slightly imperfect look flat gradients just can't give you.

Hey Product Hunt 👋 Most gradient tools give you clean, predictable results. I wanted something different — gradients that actually carry mood and texture, something closer to a feeling than a formula. There was no real reference for this, so I had to imagine the tool before I could build it. The hardest part was translating something as fuzzy as "mood" into controllable settings — texture, blur, direction — that still export cleanly as PNG/JPG. Alongside the web app, I also built a Figma plugin with the same functionality, plus a small design system and visual identity to tie it all together. Rennu is completely free, no account needed. Would love to hear what you create with it — and any feedback on what you'd want to see next!
