Show HN: ReviewReply — AI review responses, 3 free per day
I built ReviewReply to solve a specific problem: restaurant and hotel owners spend 15-20 minutes per review response, or more commonly skip it entirely.
What it does: Paste any customer review from Google, TripAdvisor or Airbnb. Get a professional, empathetic response in about 3 seconds. No account needed.
Stack: Cloudflare Worker + KV, Claude Haiku for responses, Claude Sonnet for the full audit product, Brevo for email delivery, Stripe for payments. Total infrastructure: $0/month.
The interesting parts:
- Rate limiting at 3/day per IP via Cloudflare KV server-side (no client trust)
- Pro activation without Stripe webhooks — validate
cs_live_session_id on redirect, generate KV token - Daily Telegram tip via Worker cron — passive audience building with zero maintenance
Products:
- ReviewReply (free/Pro $19/month) — one reply at a time
- ReviewScan ($29 one-time) — full audit of all reviews, email delivery within 2 minutes
Live at reviewreply.pages.dev.
Curious whether the output quality reads as genuinely professional or as obviously AI-generated.
