Supastack is a software-as-a-service boilerplate designed to accelerate the development of multi-platform applications. It provides a single TypeScript codebase that can be deployed across web, mobile, and desktop environments. The boilerplate includes preconfigured integrations for authentication, payments, artificial intelligence workflows, email, and search engine optimization. Users purchase the boilerplate once and can build an unlimited number of personal and client applications with it. The platform offers a range of built-in features. Authentication supports email, one-time passwords, and social sign-in through Google and GitHub, all scoped to a personal workspace. Payment handling includes checkout flows, customer portals, and webhooks across eight payment providers, with Stripe as a primary option. AI workflows allow users to bring their own provider keys, route between providers, and set spending caps. Additional capabilities include background job processing, transactional email through a unified send interface, file uploads to S3-compatible storage, and an in-app notification system with mobile push and threaded replies. Typical use cases involve building SaaS products that require user accounts, subscription billing, and AI features. Developers can start with a personal workspace that can later expand into full organizational structures with permissions, audit logs, and workspace-scoped activity history. The boilerplate also includes token tracking and budget management to prevent runaway spending, as well as sanitized exception and event logging with workspace context. From a technical standpoint, Supastack uses a single TypeScript codebase and provides a typed client along with command-line tools for connecting applications. Provider keys remain encrypted and server-side only. The product is licensed per purchase, with a limited number of licenses available at a discounted price before a scheduled increase.
