Capybara Onsen
by Chinese
A hot spring that is always open. Everyone who opens the link appears as a capybara in the same water — and the capybaras who live there remember you between visits.

About This Project
Capybara Onsen is a hot spring that never closes. Open the link and you're already in the water — no sign-up, no lobby, no loading screen. Everyone else with the link is in the same pool, live.
Three capybaras actually live there, and they remember you. Tell Yuzu-sensei you've had a hard week and he'll ask how it went tomorrow. Mention it to Momo instead, and Kinako pipes up from across the pool already knowing — the residents gossip about you between themselves. 🧠
Built end-to-end on InsForge 🍊 — realtime presence and broadcast, Postgres with RLS, pgvector for the memories, Model Gateway for the dialogue, edge functions, cron, storage, auth, payments, and hosting. We wrote no backend server. There isn't one.
