Wallogen
Make your own wallpaper in a few seconds. Pick a style (or just describe one in words), tweak the colors, and download it at your screen's exact size, up to 8K.
Free. No sign-up. Your wallpaper is drawn right in your browser.
Try it: wallogen.vercel.app
What it does
- 18 styles: waves, auroras, glass, mountains, light rays, and more.
- Describe it: type something like "calm ocean at dusk" and AI picks the style and colors for you.
- Any screen: presets for 4K and 8K monitors, ultrawides, iPhones, Android phones, and iPads. You can also type your own size.
- Make it yours: change the colors, size, detail, grain, and angle with sliders.
- Private: no accounts and no tracking. If you use the AI box, only the words you type are sent out. The image itself is never uploaded.
Run it on your computer
You need Node.js 18 or newer.
git clone https://github.com/denzeltl/wallogen.git
cd wallogen
npm install
npm run dev
Then open http://localhost:3000.
Turn on the AI box (optional)
The app works without this. Without a key, the AI box matches your words to a style on your device instead.
- Get a free key from Groq. A Gemini key also works as a backup.
- Copy
.env.example to .env.local and paste your key(s) in.
- Restart
npm run dev.
Keep these keys secret. Don't commit .env.local.
