Everything Your SaaS Needs, Built In
Production-ready features, built completely. Stop reinventing the plumbing — start building what makes your product different.
Self-hosted authentication
Email, password, and social sign-in powered by Clerk — sessions, MFA, and webhooks wired end-to-end.
Multi-tenancy & teams
Organizations, invitations, roles and per-tenant data isolation enforced at the Prisma layer.
Stripe billing
Subscriptions, customer portal, usage metering and webhook-driven sync — flexible from day one.
Complete UI foundation
shadcn/ui components, dark mode, responsive layouts, charts and forms with React Hook Form.
Transactional email
Resend + React Email templates for welcome, invitations, password resets and receipts.
Production database
Prisma 7 connected to Neon with serverless pooling, migrations and typed queries baked in.
Permissions & RBAC
Role-based access at the route and component level — protected dashboards out of the box.
Webhooks & integrations
Clerk + Stripe webhooks verified, idempotent and ready for production payloads.
Notifications
Toast notifications via Sonner and a sane pattern for in-app activity feeds.
i18n ready
next-intl preconfigured so you can ship in multiple languages when you're ready.
Type-safe everything
Strict TypeScript, t3-env validated environment variables, and Zod-powered server actions.

Developer Productivity
“Shaved months off our launch. Auth, billing and multi-tenancy were already wired — we shipped the actual product instead of the plumbing.”
Priya Anand
Founder, Slatework
“The codebase reads like something a team would write at year three, not day one. Clean conventions, zero magic.”
Marco Bellini
Staff Engineer, Northvane
“Stripe + Clerk + Prisma + Neon already talking to each other — that alone paid for it twice over.”
Hana Park
CTO, Threadly
“Best money I've spent on a side project. Replaced a stack I'd been gluing together for two weeks.”
Owen Walker
Indie Hacker
“TypeScript-strict, env-validated, webhook-verified. It feels like a senior engineer set up the repo for you.”
Sofia Reyes
Tech Lead, Helio
“We replatformed in a weekend. The org and roles model alone would have taken us a sprint to design.”
Daniel Yu
Co-founder, Inboxer
