All three Supabase kits in one download: shared subscription (web + mobile), account deletion + data export, and production hardening. EUR 39 instead of EUR 57 bought separately. Subscribe on web or mobile and unlock both; ship the in-app account deletion Apple and Google require plus a GDPR export; and lock the app down with rate limiting, per-user caps, private storage, and an immutable audit log. Every kit is real production code, generalised, with its own setup README. Single-project commercial use. The full write-ups behind these kits: one subscription across web and mobile, rate limiting in Postgres with no Redis, and account deletion that satisfies the app stores. All three kits now ship an AGENTS.md so Claude Code or Cursor can install them directly: install order, the mandatory config edits, and a verification step for each.
