--- title: "Best Multi-Tenant SaaS Boilerplates in 2026" description: "Multi-tenant SaaS boilerplates compared: Supastarter, Makerkit, Bedrock, and Volca. Pricing, data isolation, and team billing — find the right B2B starter." date: "2026-03-08" tier: 2 authors: ["team"] tags: ["multi-tenancy", "b2b", "boilerplate", "saas", "2026"] featured_boilerplate: "Supastarter" --- ## TL;DR verdict The approved current evidence supports a two-product shortlist: **Supastarter** and **MakerKit**. Both document organizations, invitations, roles or permissions, and organization billing. They do not use one identical tenancy implementation, license model, or feature set. Use a source-bounded shortlist and verified decision criteria: stack, tenancy model, billing providers, data isolation, license, developer seats, project-use rights, update entitlement, support, and code access. Bedrock, Volca, and Nextacular are intentionally omitted from the current matrix because the frozen packet contains no approved current first-party identity/source record for their claims. ## Key Takeaways - **Supastarter $299/$799/$1,499:** the checked page listed Solo, Startup, and Agency as paid-once commercial offers. - **MakerKit $349/$649:** the checked page listed Pro and Teams as lifetime commercial offers for its current Supabase kit. - Product-specific tenancy matters. Supastarter and MakerKit document different application and database interfaces; do not claim every starter uses PostgreSQL RLS. The guide keeps documented current capabilities tied to their source. - Clerk Organizations documents membership, roles, permissions, and **Clerk active organization** session context. It does not prove an unverified starter wires Clerk organization IDs into database policy. - PostgreSQL RLS can enforce row policy, but table owners and roles with `BYPASSRLS` normally bypass it. Test the owner and BYPASSRLS caveats in the production connection model. - There is no comparable first-party ratings dataset for the products in the old matrix, so review counts and popularity rankings are removed. ## At-a-glance table Values were accessed 2026-08-22. | Starter | Verified current organization surface | Verified billing/data surface | Checked commercial offer | |---|---|---|---| | Supastarter | Organizations, member invitations, roles, configurable organization use | Seat-based billing; Stripe, Lemon Squeezy, Creem, or Polar documented | Solo $299 once; Startup $799 once; Agency $1,499 once | | MakerKit | Organizations, invitations, RBAC | Stripe billing; Supabase Auth, Storage, Database, and RLS documented | Pro $349 lifetime; Teams $649 lifetime | The table does not include Bedrock, Volca, or Nextacular. Unfrozen products omitted from a comparison are preferable to unsupported current prices, licenses, and features. ## What a multi-tenant starter must prove A B2B starter should expose clear interfaces for five jobs: 1. **Membership:** create an organization, invite a person, accept or reject the invitation, and remove a member. 2. **Authorization** — Define roles and permissions, then enforce them at every server-side action. 3. **Active context:** bind the request to the selected organization and prevent context changes from crossing authorization rules. 4. **Billing:** attach the subscription, plan, and seat count to the correct organization. 5. **Data isolation:** scope reads and writes at the application layer, database layer, or both, with explicit privileged-access behavior. A checklist is not proof. Inspect routes, server actions, policies, migrations, tests, background jobs, webhooks, and admin access before buying or shipping. ## Product-specific tenancy ### Supastarter The checked Supastarter page documents organizations, member invitations, roles, configurable organization use, seat-based billing, and several payment-provider options. That is documented current capability, not a guarantee that its defaults match your authorization or billing model. Its current named commercial offers were: - Solo: $299 once; - Startup: $799 once; - Agency: $1,499 once. Confirm developer seats, project-use terms, code access, support, and update entitlement for the selected tier. Paying once describes purchase cadence; it does not by itself describe redistribution or lifetime-update rights. ### MakerKit MakerKit's checked Supabase offering documents organizations, invitations, RBAC, Stripe billing, and Supabase Auth, Storage, Database, and RLS. The checked commercial offers were Pro at $349 lifetime and Teams at $649 lifetime. Treat “lifetime access” as the vendor's named commercial offer and still review tier-specific terms. Confirm project count, developer seats, updates, support, and any limits that affect a team purchase. ## Data isolation: verify the actual layer Do not assume every multi-tenant boilerplate uses PostgreSQL RLS merely because it has organizations. ### Application scoping Application code can bind every query to the active organization: ```typescript const documents = await db.document.findMany({ where: { organizationId: session.activeOrganizationId, }, }); ``` This interface must be hard to bypass. Review service methods, server actions, webhooks, jobs, and admin tools—not only page loaders. ### PostgreSQL row-level security RLS can add a database policy seam: ```sql ALTER TABLE documents ENABLE ROW LEVEL SECURITY; CREATE POLICY tenant_isolation ON documents USING (organization_id = current_setting('app.current_org_id')::uuid); ``` The policy is only one part of the design. PostgreSQL documents that table owners and roles with `BYPASSRLS` normally bypass row security. Verify which database role the application uses, how the tenant setting is established, whether connection pooling can leak context, and how privileged operations are audited. ### Clerk organization context [Clerk Organizations](https://clerk.com) supplies organization membership, roles, permissions, and active-organization session context. Those are auth and session primitives. They do not prove that a particular starter enforces database isolation. The application must still bind its data access and billing operations to that context. ## Team billing checks A starter's billing demo should not decide your product model. Verify the exact workflow: - which organization owns the customer and subscription IDs; - whether seats are billed immediately, prorated, or at renewal; - how invitations affect seat count; - how failed payments and downgrades affect access; - whether usage, credits, taxes, invoices, and refunds are supported; - how webhooks are retried and reconciled; - whether an organization transfer changes billing ownership safely. Supastarter documents seat-based billing with several named payment providers. MakerKit's checked Supabase product documents Stripe billing. Do not transfer one product's provider list to the other. ## License and purchase boundaries Supastarter and MakerKit are commercial offers. Record developer-seat and project-use terms exactly by tier. The checked pages describe lifetime or paid-once access signals, but purchase cadence, code license, redistribution rights, updates, and support are separate terms. Do not assign Bedrock, Volca, or Nextacular a free, MIT, paid-once, or subscription label from the current packet. The rule is to **omit products without current first-party records** for those claims. Prices and plan names change. Recheck both vendor pages immediately before purchase or publication. ## Methodology This refresh uses the five approved first-party sources in the frozen StarterPick packet. The product order remains unchanged where a product is still eligible, but unsupported products are omitted from the current matrix. We separate documented capabilities, auth context, database behavior, commercial offers, and comparative judgment. Source reachability is access-time availability only. It does not establish active maintenance, future support, production readiness, review quality, or a winner. The old review counts, ratings, customer counts, implementation-time estimates, and superlatives lacked a comparable first-party dataset and were removed. The separately owned observability route `/guides/ai-agent-saas-observability-evals-2026` remains excluded and untouched. ## Best fit cards ### Choose Supastarter if Its integrated organization and seat-billing surface, named payment providers, selected tier, and codebase shape match your product. Review the larger inherited surface rather than treating “more features” as an automatic advantage. ### Choose MakerKit if Its current Supabase organization, RBAC, Stripe, and RLS model matches the stack you want to operate. Verify the exact Pro or Teams rights before purchase. ### Build the tenancy layer yourself if Your domain requires an isolation model, billing contract, privileged-access workflow, or deployment architecture that the inspected starters do not expose cleanly. Budget for policy tests, webhook tests, organization-context tests, and recovery procedures. ## Affiliate and data disclosure StarterPick does not use private ratings, customer-count, performance, or popularity data for this guide. The source set provides no comparable first-party ratings system. Product links are editorial references in this refresh; commercial terms must be verified on the vendor's current checkout. ## Source notes Sources accessed 2026-08-22: - [Supastarter multi-tenancy template](https://supastarter.dev/nextjs-multi-tenancy-template) - [Supastarter FAQ](https://supastarter.dev/faq) - [MakerKit](https://makerkit.dev/) - [Clerk Organizations overview](https://clerk.com/docs/guides/organizations/overview) - [PostgreSQL row security policies](https://www.postgresql.org/docs/current/ddl-rowsecurity.html) ## Related guides - Compare [MakerKit and Supastarter](/guides/makerkit-vs-supastarter-2026). - Read the [multi-tenancy SaaS boilerplate buyer's guide](/guides/multi-tenancy-saas-boilerplate-buyers-guide-2026). - Compare [ShipFast, Supastarter, and MakerKit](/guides/shipfast-vs-supastarter-vs-makerkit-2026).
