A channel that already hypes a drop, then dies in Direct. The Mini App opens at a timestamp, locks inventory, takes the invoice, and closes. How I would ship the clock without building a full shop.
Not Jira in a webview. A small board opened from a work group: three columns, haptic on move, a bot line when a card hits done. Why `chat_instance` is the board, and what I would refuse to build.
The interesting Mini Apps in 2026 are not Hamster copies. Seven product patterns I would actually steal: group-native tools, a dual PWA door, exclusive drops, internal ops, one-job AI, matching without a fleet, and Stars as the receipt - not the product.
A concrete Mini App for a trip, a flat, or a small team: open from the group, log who paid, simplify debts, settle with Stars, an invoice, or TON. Why `chat_instance` is the workspace, and what I would ship first.
