The last SaaS boilerplate you'll ever need. A complete, production-ready SaaS foundation built entirely through conversation with Claude Code.
The bottleneck for building software isn't engineering capacity anymore — it's imagination. LastSaaS proves it: a single person with a clear vision and an AI agent can stand up what used to require a team and months of work. Now anyone can stand up a complete SaaS business using Claude Code.
What You Get
Every SaaS product needs the same foundation: user accounts, teams, roles, authentication, admin dashboards, billing, usage limits. LastSaaS gives you all of it — production-tested and ready to customize for your specific product.
Authentication
Email/password, Google OAuth, JWT tokens, email verification, password resets, account lockout — the complete auth stack.
Multi-Tenancy
Tenant isolation, role-based access (owner/admin/user), team invitations, ownership transfer. Your customers get their own workspace.
Billing & Credits
Subscription plans with entitlements, usage credits with dual buckets (subscription + purchased), credit bundles, billing waivers.
Admin Interface
Full admin dashboard: users, tenants, plans, system logs, configuration, messaging, health monitoring — all with a dark-themed UI.
Health Monitoring
Real-time CPU, memory, disk, HTTP, MongoDB, and Go runtime metrics. 8 time-series charts with multi-node support and threshold alerts.
Production Ready
Docker multi-stage build, Fly.io deployment, CORS, security headers, rate limiting, graceful shutdown. Ships in a 14MB container.
Built for the Creator Era
Software is entering its creator era. The same way YouTube democratized video and Substack democratized publishing, AI agents are democratizing software itself. The person with the idea can now be the person who ships it.
LastSaaS was built entirely through conversation with Claude Code — not as a novelty, but as proof of a new way of working. Every feature, every handler, every component was described in natural language and implemented by an AI agent. The human provided the vision, the architecture, and the design decisions. The agent handled the implementation.
This isn't a scaffold or a generator. It's a living codebase that you can continue building the same way it was created: describe what you want, and let your AI agent implement it on top of patterns that already work.
