Frequently Asked Questions
What is the best SaaS starter template?▾
Next.js SaaS Starter, Shipfast, and Supastarter are popular choices. Evaluate based on your specific needs for auth, billing, and included features.
How do I handle multi-tenancy?▾
Use a shared database with tenant ID columns for simplicity, or separate schemas per tenant for stronger isolation. Row-level security in PostgreSQL works well for most SaaS apps.
When should I add team features?▾
Add basic team support from the start if your target market is businesses. Individual-only accounts are hard to retrofit into team-based products later.
