Optimized for AI Coding

No noise. Just value.

Everything you need. Nothing you don't.

Multi-Tenant Architecture

Single-database tenancy with middleware isolation, tested by design. Users, roles, permissions, scoped by tenant.

Production Billing Engine

Flat, seat-based, and usage-ready pricing. Stripe Tax integration. Strict currency invariants. Webhook-safe lifecycle.

Subscriptions

End-to-end subscription flows with Stripe. Trials, upgrades, proration, and webhook-safe lifecycle handling out of the box.

Entitlements & Feature Gating

Define feature access and quotas per plan. Centralized entitlement system to control capabilities across your entire application.

Webhook-Safe by Design

Idempotent Stripe webhook handling with full lifecycle synchronization. Built to handle real-world edge cases reliably.

Teams & Invitations

Invite users, assign roles, manage seats. Built-in invitation flow with email notifications.

User Impersonation

See exactly what your users see. Impersonate accounts securely to diagnose issues and provide faster support.

Multi-Currency Ready

Strict currency invariants with no hidden conversions. Reliable multi-currency support designed for real billing scenarios.

Internationalization

EN/FR/ES/IT out of the box. Translatable models via dedicated translation tables (not JSON columns).

Settings System

Three-tier preferences (App → Tenant → User) with cascading resolution and caching.

Content Management System

Nuxt Studio integration for visual content editing. Structured, versionable content without breaking your application architecture.

API-First Design

Laravel Resources as source of truth, Zod schemas for frontend validation, snake_case standardized.

AI-Ready Architecture

Built for humans and AI agents. Clear structure, explicit contracts, and predictable patterns for high-quality AI-generated code.

Admin & Manager Panel

15+ ready-made pages: analytics, user & tenant management, roles, product catalog, currencies, and settings.

Revenue Analytics

Built-in MRR, ARR, churn rate, and revenue-per-plan dashboards with interactive charts. Enterprise-grade metrics without a third-party tool.

Deep Metering & Quotas

Track usage with meters, events, and four aggregation modes. Enforce quotas with soft or hard limits, snapshots, and automatic reconciliation.

Real-Time WebSockets

Laravel Reverb included as a Docker service. Broadcast admin and tenant events instantly for live dashboards and notifications.

Push Notifications

Web push via VAPID out of the box. Tenant-wide notification jobs with subscription management — production-ready, not a proof of concept.

Multi-Step Onboarding

Guided onboarding flow with dedicated controllers, progress tracking, and checkout retry. Middleware ensures every step is completed before access is granted.

Docker-based Development

Zero-config development environment. Run the full stack with Docker and start building immediately.

Clean Architecture

Clear separation between domain, application, and infrastructure layers. Maintainable, testable, and designed for long-term evolution.

Built to last

Architecture is what you feel 6 months later

SaaS4Builders follows clean DDD-inspired separation between Domain, Application, and Infrastructure layers. Every decision is documented. Every boundary is explicit.

Clear separation of concerns. Tested business logic. No God classes. No hidden coupling. Architecture decisions documented with rationale. So, you (and your clients) understand the why.

Domain Layer

Models, Value Objects, Enums, Business Rules, Invariants

Application Layer

Actions, DTOs, Services, Use Cases

Infrastructure Layer

Repositories, Providers, Stripe, External APIs

Designed for real-world billing

Billing designed for evolution, not shortcuts

Plan Selection

Internal Price Calculation(shadow)

Stripe Subscription + Tax

Stripe Invoice(source of truth)

Webhooks

Local Sync

Reconciliation

No shortcuts. Just solid foundations

Designed for what comes next

A complete billing architecture built for correctness, not convenience. Shadow validation, strict currency invariants, tax-aware flows, and a clear evolution path beyond Stripe-managed billing.

Stripe-managed today. Evolution-ready tomorrow.
Strict currency invariants enforced at the domain level.
Explicit proration rules, no hidden behavior
Webhook idempotency built in.

Built with intent

Not another boilerplate. A foundation.

You know this already

You've built this before. Every. Single. Time.

Authentication, multi-tenancy, billing, teams, permissions, webhooks, invoice generation, subscription lifecycle management…

Every new SaaS project starts with the same 8-14 weeks of infrastructure work. The same decisions. The same traps. The same "we'll clean this up later" that never happens.

What if that foundation was already built — and built right?

Made for builders

For developers who build for others

SaaS4Builders is a structured foundation designed for developers who deliver real products to clients and need something they can trust over time.

Clear architecture, explicit constraints, and production-ready patterns. No shortcuts. No hidden complexity.

Freelancers & Consultants

You deliver SaaS products to clients. You need a foundation you can reuse across projects, defend in code reviews, and maintain long-term.

Agencies & Dev Teams

Your team ships multiple SaaS products per year. You need consistent architecture, documented decisions, and a starting point that doesn't create technical debt.

Serious Indie Builders

You're building a SaaS that needs to scale. You care about architecture, not just velocity. You want a production base, not a hackathon template.

What this is. And what it isn't.

This is not

A no-code website builder
A theme pack or UI kit
A hackathon starter
A completed SaaS product

This is

A reusable SaaS foundation for Laravel + Nuxt
Architecture you can defend to clients and teammates
A structured starting point for production-grade projects
Documented, tested, and opinionated

From early adopters and beta testers.

"Beta version helped me move much faster on my SaaS. Instead of spending time on auth, billing, and edge cases, I could focus on the product itself. Instead of rebuilding the basics, I could focus entirely on the core features."

Thomas

Freelance Web Developer

"I've built this kind of stack multiple times, and this is the first time I didn't feel like I had to rewrite parts of it after a few days. The architecture is well thought out, especially around billing and domain rules."

Jérôme

Indie SaaS Founder

"I got early access and used it on a client project. It saved me weeks of setup, especially on billing and multi-tenancy. What I appreciated most is that nothing feels hacky."
