LINE Mini App Development

Reach customers inside LINE with mini apps that need no download, no install, and no new account.

View Case Studies

LINE is where your customers already are: 56 million people in Thailand, 97 million in Japan, and 22 million in Taiwan use it to chat, pay, and follow the brands they care about. A LINE Mini App puts your product inside that conversation, with no app store and no sign-up form between a broadcast and a purchase.

We design and build LINE Mini Apps end to end on LIFF and the LINE platform: chat commerce, bookings, loyalty, and payments, wired into your official account so every rich menu tap and chatbot reply opens straight into a working product.

Challenges

Key Challenges

Understanding the critical obstacles that drive digital transformation in this industry.

The App Download Barrier

Most customers will not install another native app for a single purchase or booking. Every download, permission prompt, and registration step cuts conversion before the experience even starts.

Fragmented Customer Journeys

Campaigns run in LINE, but checkout happens on an external website. Each switch between chat, browser, and app drops customers and breaks the thread between marketing and sales.

Costly Re-engagement

Push notifications get declined and emails go unread. Brands need a channel customers actually open, where a message leads directly into a product instead of linking away from one.

Platform Expertise Gap

LIFF, the Messaging API, flex messages, rich menus, and the Mini App review process form a stack of their own. Few teams have designed and shipped production apps on it.

Chat Commerce & Official Accounts

Chatbots, rich menus, quick replies, and flex messages that turn your LINE official account into a storefront with a conversation built in.

Payments Inside LINE
