Plunxo
A Next.js starting point with the parts you rebuild for every service — subscription billing, social sign-in, AI integration — already wired up.
Sign-in
ReadyGoogle, Kakao, and email magic links together. Sessions live in the database so the server can end them instantly, and abuse limits are built in.
Billing
PlannedPortOne connects Toss Payments for both subscriptions and one-off purchases. Webhooks are re-checked server to server before anything is applied.
AI
PlannedUsers drop in their own API key and it works. Keys are stored encrypted, with per-plan usage limits alongside.
Still under construction. Pricing and purchase pages come in a later step.
