CosmoScape

Space imagery is stunning — but most people have no idea what to type into a prompt box. Nebulae, accretion disks, magnetars: the terminology is foreign, and a blank text field doesn't help. CosmoScape was built around that problem. Instead of open prompts, users browse predefined categories and make selections that feel intuitive, even if they couldn't name what they're looking at.

The result is a product that's genuinely accessible. You don't need to know space to get something beautiful out of it.

On the technical side, the challenge was making 2K–4K generation feel smooth in the browser. Lazy rendering and client-side caching mean images stream in as they finish rather than blocking the UI — important when generation takes time and impatient users tend to refresh. The layout handles everything from mobile to 4K displays cleanly.

Under the hood: a Node.js API managing the async generation pipeline, a credit-based system with Stripe payment integration, JWT auth, and full user state persistence so credits never disappear on refresh.
