I Built an Anonymous Feedback App for Telegram — Here's What I Learned

I Built an Anonymous Feedback App for Telegram — Here's What I Learned Remember Sarahah? The app that went viral in 2017, hitting #1 in 30+ countries with zero marketing budget? The concept was dead simple: share a link, get anonymous messages from friends. I built something similar — but inside Telegram as a Mini App, with native monetization through Telegram Stars. Here's the full story. 🎯 The Idea WhisprMe (@WhisprMe_bot) is an anonymous feedback service built as a Telegram Mini App. You get a unique link, share it with friends, and they write anonymous messages to you. The hook? You can see a 3-word preview of each message, but the full text is blurred. Want to read it? Pay 15 Stars (~$0.26) or invite a friend. The tagline: "Find out what people really think about you" 🏗️ Tech Stack Layer Technology Backend Node.js + Express Database PostgreSQL (raw SQL, no ORM) Frontend React (Create React App) Bot Telegraf.js Process Manager PM2 (cluster mode) Web Server nginx Payments Telegram S
