SvelteKit SaaS Boilerplate: What You Actually Need
You're building a B2B SaaS with SvelteKit. You need a starter that handles the hard parts — multi-tenancy, RBAC, billing, audit logging — so you can focus on your product.
Here's what to look for, what free starters provide, and what you'll need to build yourself.
What every B2B SaaS needs (but few starters include)
Multi-tenancy
Every B2B SaaS needs organizations. Users belong to orgs, not just accounts.RBAC
Owner > admin > member hierarchy with capability matrix. Server-side enforcement.Seat billing
Charge per seat. Pluggable adapter for any merchant-of-record.Audit log
Who did what, when. Append-only by construction. Enterprise requirement.Rate limiting
Protect login from brute force. Sliding window, per-IP+email.Tests

Skeleton
Includes: UI components, basic auth
Missing: Multi-tenancy, RBAC, billing
SKsingularity

These are great starting points for prototypes and MVPs. But for production B2B SaaS, you'll need to build multi-tenancy, RBAC, billing, and audit logging yourself.
The math: build vs. buy
Building RBAC from scratch: 2–4 weeks for a senior engineer. That's $5,000–$20,000 in opportunity cost.
Building seat billing: 1–2 weeks to integrate a merchant-of-record. Plus ongoing maintenance.
Building audit logging: 1 week for append-only design, query interface, and export.
Total build cost: 4–7 weeks, or $10,000–$35,000 in opportunity cost.
Production starter cost: our starters run $79–$149 depending on the data layer (SQLite vs Postgres). One-time. Tested. Documented.

- Tests — comprehensive coverage of the hard parts
- Documentation — architecture, patterns, how to extend
The verdict
Free starters are great for learning and prototyping. For production B2B SaaS, you need a starter that handles the hard parts — multi-tenancy, RBAC, billing, and audit logging — so you can focus on your actual product.
The Multi-tenant SvelteKit Starter includes all of these features, tested with 77 tests, and priced at $79–$129.
