Introduction

As the sole developer on whspr, my goal was to ship a product that people could trust with their most honest thoughts — one that felt premium, loaded instantly, and kept every sender completely anonymous. I handled everything from schema design and API routes to the landing page animations and responsive theming.

Project Overview

whspr is a full-stack anonymous messaging SaaS built on Next.js (App Router) with a Neon serverless Postgres database and Resend for transactional email. Users register with a unique username and receive a shareable profile URL. Anyone visiting that URL can type a secret message and submit it without signing in — their IP address, location, and browser fingerprint are never stored. The receiver logs into a private dashboard to read, manage, or delete messages. The platform supports multiple link aliases on paid tiers, a username-change flow, and a freemium billing model. The entire stack is deployed on Vercel's edge network, delivering sub-100 ms response times globally.
