How I Built an AI Pet Video Generator with TanStack Start and ByteDance Seedance

A few months ago I set out to build something that felt genuinely magical. Not another CRUD dashboard, not another productivity tracker. I wanted to build something my non-technical friends would actually use and enjoy.

The result is is live and free to try. Upload a photo of your pet, give it a prompt, and see what Seedance 2.5 can do. No credit card, no time-limited trial — just one generation a week you can actually use and download.

If you're curious about the underlying SaaS architecture — auth, payments, admin panel, the credit engine — the backend runs on ShipAny, a headless SaaS boilerplate. Their source is on . I mention it because a lot of indie devs burn weeks on infrastructure before they ever write a line of product code. Having that layer done meant I went from idea to working prototype in about a week.

Would love to hear what you're building — or how you'd approach this differently. Drop a comment.
