Makerkit

Makerkit is a SaaS starter kit that gives developers a production-ready foundation covering authentication, team and organization management, subscription billing, and a dashboard UI, built for frameworks like Next.js and Remix, so a developer building a new SaaS product can skip re-implementing the same foundational features that nearly every SaaS product needs regardless of what its core product actually does. Its multi-tenant architecture supports organizations with multiple team members and role-based permissions out of the box, which is a common requirement for B2B software but is genuinely time-consuming and easy to get subtly wrong when implementing it correctly and securely from scratch for the first time. Billing integration is pre-configured to handle subscription lifecycle events like upgrades, downgrades, and cancellations, including the webhook handling needed to keep a database in sync with a payment processor's actual billing state, which is one of the more error-prone pieces of SaaS infrastructure to build correctly without a reference implementation to start from. Makerkit's codebase follows current best practices for the frameworks it's built on, using patterns and tooling that a developer would reasonably want to build a maintainable production application with, rather than a quick prototype-quality template not meant for real, ongoing production use. Because it's sold as source code the buyer owns rather than a hosted platform, developers can customize any part of the codebase as their product's specific needs diverge from the starting template.
