Show HN: Lettoral – Send one message, get one back. No social hack

https://lettoral.com
1•hayner•1h ago
Lettoral is a web app where you send one message and receive one back from a stranger. There are no profiles, following, or likes.

I built this because I wanted a place to share those small thoughts—things that aren't big enough for social media, or something you wouldn't necessarily tell family or friends, but feel like a waste to just keep buried inside. Even if there’s no specific punchline, it’s for those moments you just want to tell someone.

Another reason was that I simply wanted to build something using vibe coding. I’m not a professional engineer. I built this strictly using Cursor, Vercel, and Supabase. (Though I did have an engineer friend give it a quick review at the very end.)

As a solo developer, I made privacy my absolute priority. IP addresses are salted and hashed so posts cannot be linked to individuals. Messages vanish typically 24 hours after being picked up to keep the encounter one-time and ephemeral.

It’s free to play and requires no login, so please give it a try. I welcome any feedback, suggestions, or technical advice! I had so much fun learning the tech for this project, and I’m genuinely curious about what professional engineers focus on or find interesting.
