What You Can and Can’t Build With Caffeine
Caffeine offers a fixed technology stack for app development, emphasizing security and data protection on the Internet Computer. Each application utilizes React, TypeScript, Tailwind CSS, and Motoko, with built-in data storage and passwordless authentication via Internet Identity. Stripe integration supports payment processing, while blob storage handles file management. You cannot add custom packages, but many JavaScript libraries can be integrated via CDNs like jsDelivr.
Limitations are significant: no support for backend languages (only Motoko), external databases, or traditional cloud providers like AWS. Furthermore, only React is allowed for the frontend, and third-party authentication options are restricted to Internet Identity. Features like real-time communication, maps, social media APIs, and external wallets are also unavailable. For best results, users should articulate their goals, allowing the AI to find suitable solutions within the existing stack.
