Hairdoo — see if you can actually pull off a haircut before you're in the chair.

Upload one selfie, pick a style (or upload a reference photo of a cut you like), and get a photo-real preview in about 15 seconds. Drag the before/after slider to compare.

What makes it different:

• No account, ever. Your looks live in your browser (IndexedDB), not on my server.

• Two ways to run it — bring your own Gemini (Nano Banana) key and it's free and fully private (your photo never leaves your device), or buy a credit pack: $9.99 for 30 previews, no subscription, no lifetime-deal nonsense.

• Fast: ~15s per preview, portrait-framed so you actually see the hair.

Stack: TanStack Start on Cloudflare Workers, D1 for anonymous credit codes, Gemini for image gen. Solo-built.

P.S: Every 'virtual hairstyle' app wants your account and your face on their server. This one wants neither."

Would love your feedback — especially which styles it renders convincingly vs. where it falls apart. 👇 hairdoo.me
