Turn your AI agent into a paid product without weeks of setup
Mastrakit is a one-time developer kit that gives you a production-ready foundation—Better Auth, billing, built-in metrics, and admin—so you can focus on your agent and start charging users.
One-time purchase. Updates included.
What slows agent products down
Building an AI agent is usually not the hard part.
What slows teams down is everything around it:
- User authentication and management
- Payments, subscriptions, and credits
- Built-in metrics and usage tracking
- Admin tooling to operate the product
- Infrastructure decisions you'll maintain long-term
Most teams rebuild this stack every time. That means weeks of setup before a user can even sign up or pay.
What Mastrakit gives you
Mastrakit gives you a production-ready baseline for agent-based products.
Instead of starting from a blank repository, you start with the core SaaS infrastructure already wired and connected.
- Better Auth for user management
- Billing for subscriptions and credits
- Built-in metrics and usage tracking
- A simple admin surface
- A working agent scaffold you can extend or replace
Install once. Build forward across projects.

Why teams use it
Faster path to revenue
Users can sign up and pay as soon as your agent is ready.
Fewer irreversible decisions
You start from a practical baseline instead of assembling infrastructure under pressure later.
Cleaner mental model
Configuration is centralized. Core logic is separated. Agents stay modular.
Easier to operate after launch
You can see users, subscriptions, and agent usage without building a full dashboard first.
Why this instead of common alternatives
Building it yourself
You spend weeks rebuilding the same SaaS plumbing before reaching users.
Generic SaaS starters
Most are designed for CRUD apps, not agent-based products.
Agent frameworks alone
Frameworks help you build agents. They don't help you run a business around them.
Subscription boilerplates
One-time purchase. Use it across projects. Updates included.
Common questions
Is this too opinionated?
Yes. The goal is to give you solid defaults you can customize, not a blank canvas that delays decisions.
Can I change or remove parts?
Yes. Agents are modular, features are separated, and configuration is centralized.
Will this scale if my product grows?
Mastrakit uses production-grade services and supports multi-tenant and team setups.
Ready to stop rebuilding the same SaaS stack?
Install once. Build your agent. Start charging users.
Trust and credibility
Built by developers shipping real SaaS products.
