Source-owned Next.js SaaS codebase

Ship your SaaS, not your shame.

Auth, organizations, RBAC, Stripe billing, CMS, media, i18n, feature flags, admin screens, and MCP operations already wired. You own the codebase. You ship the product.

The boring stuff, wired as a system

Not a pile of starter snippets. A connected SaaS spine.

The design goal is simple: make every operational surface talk to the others before your product logic arrives.

Talk to my SaaS

Your site, catalog, pages, media, and offers are operable through MCP.

That is the difference between a starter and an operating system: trusted agents can inspect, draft, validate, diff, and publish with audit trails.

Pages, CMS data, media, design tokens, and billing catalog live behind tools.

Open-source proof, not decoration

Your admin tables are quietly eating the roadmap.

Sorting, grouping, global search, typed filters, calculations, column state, URL state and i18n are not checkbox features. They become product infrastructure. YaYaw Table is the open-source proof: serious table UX, owned in your codebase.
