Cat Card Studio - Make adorable cat greeting cards — free, no sign-up

Hi everyone, I made Cat Card Studio because I wanted to send friends cards with my own cat drawings, and every tool I tried either wanted an account, slapped a watermark on the result, or locked the good stickers behind a subscription. So this one is just free. No sign-up, no watermarks, nothing to install. You open it in the browser, pick a background, drop in stickers, add your text, and download or print the card. All the art is hand-drawn — the cats, the comic-style effects, the flowers, the holiday stuff. No stock clipart anywhere. That's probably the thing I'm most proud of, and also the thing that took the longest. It started as a small thing for friends and family and slowly grew into something I figured other people might enjoy playing with too. If you try it, I'd genuinely love to hear what sticker packs you'd want next — more holidays, dogs, something weirder. I'll be around in the comments all day.
