NewMulti-tenant auth, billing, and orgs — ready to ship
Build your SaaS without rebuilding the foundations
A production-minded TanStack Start kit with authentication, organizations, billing, and the UI patterns you need to launch faster.
Product
Everything between signup and scale
Opinionated defaults for the hard parts of a SaaS — so your team can focus on the product customers pay for.
Teams and organizations
Invite members, manage roles, and keep every workspace isolated from day one.
Multi-tenant structure is built in: create an organization, invite your team, and switch contexts without custom scaffolding.
Owners, admins, and members get clear permissions out of the box.
Email invitations and join flows are wired for real onboarding, not demos.
Users move between organizations without losing their place in the product.
Billing that stays out of the way
Subscriptions, trials, and customer portals with a clean plan catalog.
Configure plans once, then let checkout and billing portals handle the rest while you keep shipping product features.
Monthly, yearly, and one-time options map cleanly to your pricing model.
Give teams time to evaluate before they commit.
Customers manage payment methods and plan changes from a portal.
Customers
Trusted by teams shipping real products
Example quotes you can replace with your own customers once you launch.
“We replaced months of auth and billing work with a foundation we could actually extend. Our first paying customers were live in weeks, not quarters.”
Maya Chen
Founder, Northline
“The organization model matched how we already sell. Invites, roles, and workspace switching just worked — we spent our time on the product instead.”
Jonas Weber
CTO, Latticeworks
“Clean defaults, clear structure, and nothing fighting us when we customized. It feels like a senior team left us a strong starting point.”
Amelia Ortiz
Product Lead, Harbor Studio
