Launch your Rails SaaS in days, not months.
The Rails + React starter with everything a real SaaS needs already wired: multi-tenant auth, Stripe billing, background jobs, admin, and an in-app AI assistant. Skip three months of plumbing and ship your idea this week.
You didn’t start a company to wire up webhooks.
Every SaaS rebuilds the same boring 80% — and gets it wrong the first time. Here’s what those weeks actually cost you before you write a single line of your actual product.
Not a template. A running app.
Pick a module — each one is production code, tested and following Rails conventions, talking to the rest of the stack out of the box.
Multi-tenancy, done right.
Every user belongs to an Account. Members join through owner, admin, and member roles; personal workspaces are created on signup; invitations ship with scoped tokens and expiry.
An assistant that actually knows your account.
Runway ships with an in-app assistant powered by Claude and account-scoped skills. Every answer is grounded in the current tenant’s real data — never a generic chatbot bolted onto the sidebar.
I built Runway because I kept losing the first month of every project to the same plumbing — tenancy, Stripe, OAuth, admin, jobs. Boring, high-stakes code that’s easy to get subtly wrong. So I extracted the parts I’d shipped five times, hardened them, and wrote the tests. Now I clone Runway and I’m building the actual product by lunch.
It’s the starter I wish I’d had. If it saves you even a week, it’s paid for itself — and you get every future update, free, forever.
Buy it once. Ship forever.
No seats, no per-tenant fees, no tiers to decode. One license unlocks the entire kit for every project you build.
