Laravel Multitenancy Laravel Package

Product Decisions This Supports

• Multi-Tenant SaaS Platform: Enables rapid development of tenant-isolated applications (e.g., customer portals, white-label solutions) by abstracting database/connection management.
• Database-Per-Tenant vs. Shared Schema: Supports both architectures (single/multi-database) with minimal refactoring, reducing technical debt.
• Build vs. Buy: Avoids reinventing multitenancy logic (e.g., tenant resolution, job isolation) while maintaining flexibility for customization.
• Roadmap Priorities:
  • Phase 1: Core tenant isolation (domains, APIs, CLI).
  • Phase 2: Advanced features (tenant-specific facades, dynamic subdomains, billing integration).
  • Phase 3: Scalability optimizations (e.g., tenant-aware caching, connection pooling).
• Use Cases:
  • B2B SaaS: Isolate customer data (e.g., CRM, project management tools).
  • Marketplaces: Separate vendor/buyer data (e.g., e-commerce, freelance platforms).
  • Regional Compliance: GDPR/CCPA isolation by tenant (e.g., EU vs. US data).
  • Internal Tools: Departmental portals (e.g., HR, finance) with shared codebases.

When to Consider This Package

Adopt This Package If:

• Your Laravel app requires tenant isolation (data, configurations, or UI) without heavy customization.
• You need subdomain-based routing (e.g., tenant1.app.com) or API-based tenant resolution (e.g., X-Tenant-ID header).
• Shared schema or database-per-tenant architectures are viable, but you want to avoid manual connection switching.
• You prioritize developer velocity over ultra-custom tenant logic (e.g., no need for tenant-specific Eloquent models).
• Your team lacks deep Laravel internals expertise but needs batteries-included multitenancy (e.g., tenant-aware jobs, Artisan commands).
• You’re using Laravel 11+ and PHP 8.2+ (hard requirements).

Look Elsewhere If:

• You need tenant-specific Eloquent models (this package uses a generic IsTenant contract; alternatives like tenancy/tenancy offer tighter model integration).
• Your multitenancy requires complex routing (e.g., path-based tenants like /tenant1/dashboard); consider gecche/laravel-multidomain.
• You’re building a highly dynamic tenant system (e.g., runtime tenant creation/deletion) with strict performance SLAs (this package is unopinionated but not optimized for edge cases).
• Your app uses non-Laravel services that can’t coexist with tenant isolation (e.g., legacy monoliths).
• You need built-in billing/subscription management (combine with Stripe/Lemon Squeezy or use tenancy/tenancy).
• Your team prefers opinionated frameworks (e.g., tenancy/tenancy provides more scaffolding for common SaaS patterns).

How to Pitch It (Stakeholders)

For Executives:

"This package lets us launch a multi-tenant SaaS platform without building multitenancy from scratch—saving 3–6 months of dev time. It handles the heavy lifting:

• Automatically routes users to their isolated tenant (e.g., acme.app.com → Acme’s data only).
• Isolates databases or schemas per tenant with a single config line.
• Ensures jobs, CLI commands, and APIs respect tenant boundaries.
• Scales with our growth—no refactoring as we add features like tenant-specific branding. We’re choosing this over custom code because it’s battle-tested (1.3K+ stars, used by teams like [Example Company]) and MIT-licensed, so we own our stack. Alternatives like tenancy/tenancy offer more scaffolding but lock us into their roadmap. This gives us flexibility to customize later."

ROI:

• Time: 70% faster than custom multitenancy.
• Risk: Proven in production; Spatie’s support for edge cases.
• Cost: Free (MIT license); no vendor lock-in.

For Engineering:

"This is a minimalist, contract-based multitenancy solution for Laravel. Here’s why it’s a great fit:

1. Unopinionated: We control tenant resolution (domains, headers, DB queries) via custom TenantFinder classes.
2. Database Agnostic: Works with single DB (shared schema) or multi-DB setups.
3. Tenant-Aware by Default:
   • Jobs: Mark classes with TenantAware or configure globally.
   • Artisan: Run commands per tenant with tenant:artisan.
   • Facades: Clear cached instances on tenant switch (via custom tasks).
4. Performance: Lightweight (~500 LOC core); no global overhead.
5. Extensible:
   • Add tasks for tenant-specific setup (e.g., load tenant configs).
   • Override default behavior (e.g., custom tenant models via IsTenant contract).

Trade-offs vs. Alternatives:

Recommendation: Use this for core isolation and pair with:

• laravel-breeze/inertiajs for tenant-specific UIs.
• spatie/laravel-permission for role-based access control (RBAC) per tenant.
• Custom middleware to enforce tenant-specific logic (e.g., feature flags).

Next Steps:

1. Spike: Implement domain-based tenant resolution in 2 hours (see DomainTenantFinder).
2. Architecture Decision: Choose shared schema vs. multi-DB based on data size/compliance.
3. Integrate: Add tenant-aware jobs and Artisan tasks in the next sprint."*
