CoreMVP vs Open SaaS
Compare CoreMVP and Open SaaS on framework, license, collaboration, payments, and deployment before choosing a starter.
Choose CoreMVP if you want a premium template for Next.js with Supabase, Organizations and Projects, and documented Stripe or Polar access paths. Choose Open SaaS if a free MIT-licensed starter built with Wasp, React, Node.js, and Prisma fits the framework you want to learn and maintain. Open SaaS is not a Next.js template.
CoreMVP is our product. We checked the sources below on October 30, 2026. This comparison describes published product information, not a private audit or a guarantee about what either application will do after you change it.
Compare the practical choices
| Decision | CoreMVP | Open SaaS |
|---|---|---|
| Cost and license | Solo $99 for one builder, Team $299 for up to five; one-time purchase with lifetime template updates. | Free and open source under the MIT license, subject to its notice requirement. |
| Framework and data | Next.js, Supabase Auth and Postgres, Drizzle, and an embedded Hono API. | Wasp with React, Node.js and Prisma. |
| Payments | Stripe or Polar, with lifetime and subscription access. | Stripe, Polar, or Lemon Squeezy; inspect the provider setup for your offer. |
| Collaboration | Personal and shared Organizations, roles and Projects. | Check its current source and docs against your specific shared-workspace and permission requirements. |
| Other included examples | Private files and account pictures. | Its README lists background jobs, S3 uploads, an admin dashboard, and an Astro blog. |
| Deployment | Vercel and Supabase deployment guide. | The Wasp deployment documentation describes supported deployment paths. |
Pick the framework you want to own
The framework choice affects how you add pages, server behavior, database changes, and deployment configuration. Open SaaS uses Wasp to connect a React client and Node.js server; its README also describes generated types and background jobs. Its Astro blog and supplied upload and admin examples may be useful if those match your product. Read the Open SaaS documentation and follow one feature from its configuration to its implementation before committing to the stack.
CoreMVP keeps the application in Next.js, with same-origin requests reaching an embedded Hono API. Its architecture guide explains where routes, services, and data access belong. If your team already intends to build on Next.js and Supabase, this gives you one documented place to extend the application without first translating the product into another framework.
Trace collaboration and payment
In CoreMVP, a person starts with a Personal Organization and can create a shared Organization, invite members, and use Projects within it. The Projects guide explains the included role behavior. That provides a concrete starting point for a product where an individual later works with a team. It does not automatically secure new tables or features you add.
Open SaaS has substantial functionality beyond sign-in and checkout, including the features in its public README. Its listed features alone do not establish whether its current workspace model matches your exact ownership and permission rules. If collaboration matters, inspect that model and budget for any changes you need rather than deciding from a feature name.
Both products document multiple payment providers. CoreMVP's billing guides connect lifetime and subscription purchases to stored access, so a successful browser return is not itself the access decision. Open SaaS lists Stripe, Polar, and Lemon Squeezy; use its published feature description to check the offer and provider path you intend to use. In either product, configure the provider and test checkout, webhook delivery, access, and cancellation or refunds for your business rules.
Decide whether the license and operating model fit
Open SaaS is free to use and distribute under its MIT license; retain the required notice. CoreMVP is a paid source license with commercial and client application rights within the purchased builder limit. A client receiving reusable source needs its own license under the CoreMVP terms. CoreMVP also includes lifetime template updates and a bounded commitment for critical security fixes within seven days; check the current pricing and terms for the details. Hosting and third-party services can cost money with either starter.
We recommend CoreMVP for a Next.js and Supabase product where the included collaboration and paid-access journeys match the intended customer experience. Open SaaS is a credible choice when its Wasp stack and included jobs, admin, or blog examples suit your application. Before choosing, identify who will maintain the framework, walk through your first paid user journey, and check the deployment and license terms against the people who will access the source.
