Backend Stack Template · Production-Ready SaaS API Starter

Backend Stack Template is a pragmatic backend foundation for founders, agencies, and product teams that need to launch SaaS APIs without rebuilding the same infrastructure from scratch on every project.

The service packages a production-minded Fastify + TypeScript codebase with authentication, database workflows, background jobs, API documentation, local infrastructure, CI, and deployment guidance already wired together.

Product Scope

  • Fast backend starter for MVPs, SaaS products, and client platforms.
  • API and worker separation from day one.
  • Authentication, organisations, memberships, RBAC helpers, API keys, and audit-log foundations.
  • Local PostgreSQL and Redis infrastructure through Docker Compose.
  • Documentation and operational guides for security, scaling, release checks, and Railway deployment.

Backend Stack

The template focuses on a clean, scalable backend architecture without forcing teams into a heavy framework.

  • Runtime: Fastify 5 with strict TypeScript.
  • Database: Prisma + PostgreSQL with migration-based production workflows.
  • Auth: Better Auth with email/password, email verification, password reset, and optional social providers.
  • Jobs: Redis + BullMQ for background processing, worker scaling, and DLQ operations.
  • Storage: Supabase-ready Postgres and Storage integration.
  • Docs: OpenAPI JSON and Swagger UI generated from route schemas.
  • Quality: ESLint, Prettier, Vitest, TypeScript checks, build checks, and GitHub Actions CI.

Developer Experience

The project is designed to help teams move quickly while keeping production concerns visible early.

  • Module generator for adding backend features with less setup friction.
  • Clear environment examples for local and production deployments.
  • npm run check quality gate covering format, lint, typecheck, tests, and build.
  • Railway deployment guidance for API, worker, and Redis services.

Access

Outcomes

  • Reduces startup time for backend-heavy products and SaaS MVPs.
  • Gives teams a secure default architecture with API, worker, database, queues, and CI already connected.
  • Provides a reusable foundation that can be adapted for client projects, internal tools, and production APIs.
