Every VerdantStack starter ships the unglamorous core of a B2B SaaS — organizations, invites, roles, seat billing, and an audit trail — typed end to end and tested where it hurts. Pick the data layer you already run.
A production-shaped B2B SaaS foundation with multi-tenancy wired end-to-end: organizations, invitations, role-based access, seat-based billing via a merchant of record, and an append-only audit log.
SvelteKit · SQLite via better-sqlite3 + Drizzle ORM
The same multi-tenancy, RBAC, billing, and audit log — running on Supabase for auth, database, and realtime. PostgreSQL with RLS as defense-in-depth.
SvelteKit · Supabase Postgres with RLS policies
The same core on real Postgres with Drizzle ORM: connection pooling, opt-in row-level security, and zero provider lock-in — deploy anywhere Postgres runs.
SvelteKit · Postgres via postgres.js + Drizzle ORM
All three kits share the same tested core — orgs, invites, RBAC, seat billing, audit log. The difference is the data layer. Use the matrix below to pick by situation, then read the notes for each starter.

All three kits ship the same tested multi-tenant core — orgs, invites, RBAC, seat billing, audit log. They differ only in the data layer. So the only real question is: which database do you already run, or plan to run? Pick by situation, not by feature list.
Do I need to scale past a single server / need Postgres features?

Am I already invested in Supabase (auth, storage, realtime)?

Do I want a free, managed, edge-native database with zero ops?
