“Picked Paddle because they're merchant of record. I didn't want to spend my life figuring out international tax as a one-man team — Paddle handles the VAT/sales tax stuff and I just get a clean payout. Made the accounting side way less scary.” — the maker, Sep 2026 ↗

“Vercel for hosting. Honestly the best part is I don't think about it — git push, it's deployed, done. No servers, no config, no 2am "why is it down" panic. For a one-person team that's everything.” — the maker, Sep 2026 ↗
