AnonyMessage

A full-stack anonymous messaging platform where users can share a unique public link and receive honest, anonymous messages from anyone — without revealing who sent them.

Features

• Anonymous messaging — Anyone with your link can send you a message without creating an account
• Email verification — New accounts are verified via a one-time code sent by email
• Google OAuth — Sign in with Google
• AI-powered suggestions — Powered by Google Gemini 2.5 Flash; suggests open-ended message prompts when composing
• Dashboard — View, delete, and paginate through received messages
• Accept / reject messages — Toggle whether your profile accepts new messages
• Shareable profile link — Each user gets a public URL at /u/<username>
