Build a midnight-vanishing social media app with Replit

A user built a complex social app with vanishing posts, media, DMs, groups and AI characters using Replit, asking whether anyone has finished such a project.

What they did

One commenter said they used Replit to build a fairly complex social web app around a fixed rule: every post disappears at midnight in the poster’s timezone. They described shipping support for image, video, text and link posts, DMs, and public, private and hidden groups, plus AI character accounts that users can tag; the only human handoff they mention was abandoning a freelance-built prototype and rebuilding it themselves on Replit in spare time.

How it went

They said the Replit version was built in two months, was being used by close to 300 people, and was far better than a prior outsourced prototype. Their comparison point was a six-month, $7,500 freelance build they called clunky and unusable.

Worth knowing

Their main practical claim is cost and speed: spare-time rebuilding on Replit took two months and, by their estimate, cost less than a decent mobile phone.
