supastack

Overview

supastack is a full-stack SaaS boilerplate and starter kit designed for building cross-platform applications across web, mobile, and desktop environments. Built by an independent software founder, the platform provides a unified TypeScript monorepo combining front-end frameworks with pre-configured backend utilities, database schemas, and third-party integrations. It is sold under a perpetual license model that allows developers to launch unlimited personal and commercial client products.

Key Features

• Multi-platform application support — The codebase supports web deployment via Next.js and TanStack Start, mobile applications using Expo, and desktop packaging through Tauri within a single monorepo.
• Multi-provider billing engine — The billing module includes prewired checkout flows, customer portals, and webhook handlers for eight payment providers, including Stripe, Lemon Squeezy, Paddle, and PayPal.
• Workspace authentication — User access control is powered by Better Auth, providing Google, GitHub, Apple, and email one-time passcode sign-ins scoped to individual or team workspaces.
• AI orchestration and cost controls — The architecture integrates with OpenAI and Anthropic compatible APIs, offering model routing, token usage tracking, and automated spend limits.
• Background jobs and messaging — Transactional email delivery and scheduled background worker tasks operate through unified backend interfaces across supported providers.
• Data persistence and storage — The platform configures relational database schemas and migrations via Drizzle ORM on PostgreSQL, alongside S3-compatible file storage pipelines.
• Redacted observability and logging — Workspace-tagged error monitoring, activity audit trails, and product analytics automatically sanitize sensitive user context and API keys.

Who It's For

supastack is designed for solo software founders, indie developers, and small engineering teams aiming to reduce setup time when launching commercial software. It is particularly relevant for builders creating multi-platform applications that demand native desktop or mobile presences alongside standard web applications. It also serves development agencies and freelance consultants who deliver white-label or custom SaaS platforms to external clients.

Notable Strengths

The platform distinguishes itself through its cross-platform scope, handling native mobile (Expo) and desktop (Tauri) distributions from the same codebase alongside traditional web applications. Its payment abstraction is unusually broad compared to standard boilerplates, shipping with native support for eight different payment processors and merchants of record. Furthermore, its commercial terms grant lifetime updates and unlimited personal or client project deployments for a one-time purchase without recurring fees.
