Show HN: Genjutsu – Dev social network where posts vanish in 24h

[iamovi]

Built this as an experiment in removing permanence from developer communication. Every post, comment, and interaction hard-deletes after 24 hours via pg_cron — not hidden, actually gone from the database.

Stack: React + Vite, Tailwind, Supabase, Vercel. Fully open source: github.com/iamovi/genjutsu

Happy to answer questions about the architecture or the ephemeral deletion logic.

If everything vanishes, why to force the creation of accounts?

[iamovi]

accounts exist so content is tied to a person, not to persist the content itself. you follow people, not posts. knowing who's active in the community still matters even when what they said yesterday is gone. anonymous ephemeral content tends to invite spam and abuse, accounts add just enough accountability without permanence.
