Top Open-Source Laravel Libraries for Building a Modern B2B SaaS
Introduction
Building a B2B SaaS application with Laravel requires a robust set of tools to handle complex features like multi-tenancy, billing, and permissions. The Laravel ecosystem offers many open-source libraries that can accelerate development while maintaining quality. This post covers the most useful libraries across key areas, explaining what each solves, its pros and cons, and when to use it.
Authentication & Multi-Tenancy
Laravel Jetstream (with Teams)
Laravel Jetstream provides a starting point for authentication, including login, registration, email verification, two-factor authentication, session management, and team support. It uses Livewire or Inertia for the frontend.
Advantages: First-party support, well-tested, integrates with Laravel Sanctum for API tokens. Teams feature provides basic multi-tenancy via team-based data isolation.
Disadvantages: Limited to simple team structures; not true multi-tenancy with shared databases. Customization can be tricky if you deviate from defaults.
When to use: For simple B2B apps where each user belongs to one team and data isolation is team-based.
Stancl/Tenancy
Stancl/Tenancy is a powerful multi-tenancy package supporting both single-database (tenant columns) and multi-database approaches. It handles domain/subdomain routing, tenant-specific migrations, and cache isolation.
Advantages: Flexible, well-documented, supports both architectures, automatic tenant resolution, and extensive customization.
Disadvantages: Steeper learning curve, may introduce complexity for simple apps.
When to use: For serious multi-tenant SaaS where each tenant needs full data isolation or custom domains.
Permissions & Roles
Spatie/laravel-permission
Spatie/laravel-permission is the de facto standard for role and permission management. It allows you to associate permissions with roles and assign roles to users, with caching for performance.
Advantages: Simple API, highly customizable, supports wildcards, and integrates with any auth system.
Disadvantages: No built-in UI; you must build your own management interface.
When to use: Almost always—it's lightweight and solves most permission needs.
Billing & Subscriptions
Laravel Cashier (Stripe)
Laravel Cashier provides an expressive interface for Stripe's subscription billing services. It handles subscriptions, invoices, coupons, and customer management.
Advantages: First-party, seamless Stripe integration, built-in webhooks, and subscription logic.
Disadvantages: Tied to Stripe; not for other gateways. May require additional customization for complex pricing models.
When to use: If you use Stripe, this is the easiest path.
Laravel Spark
Laravel Spark is an official package that provides a complete billing portal with team billing, subscription plans, and invoicing. It builds on Cashier.
Advantages: Full UI for billing management, team billing, and plan switching.
Disadvantages: Paid, opinionated, and may be overkill for simple apps.
When to use: When you need a quick, feature-rich billing UI and don't mind paying.
Queues & Job Processing
Laravel Horizon
Laravel Horizon provides a dashboard and configuration for Redis queues. It monitors queue throughput, job failures, and allows supervisor configuration.
Advantages: Beautiful UI, real-time monitoring, auto-scaling workers, and failure tracking.
Disadvantages: Requires Redis, may be overkill for small apps.
When to use: When you use Redis and need advanced queue management.
Monitoring & Error Tracking
Laravel Telescope
Laravel Telescope is a debug assistant that provides insight into requests, exceptions, logs, queries, and more. It's great for local development and production debugging.
Advantages: Comprehensive insights, easy setup, elegant UI.
Disadvantages: Can slow down production if not used carefully; should be restricted to authorized users.
When to use: For development and debugging in non-production environments, or with proper authorization.
Auditing & Logging
OwenIt/laravel-auditing
OwenIt/laravel-auditing tracks changes to Eloquent models, storing old and new values, user responsible, and timestamps.
Advantages: Simple trait-based setup, customizable, supports multiple storage drivers.
Disadvantages: Can increase database size; may need pruning.
When to use: For compliance or when you need a history of changes to sensitive data.
API Integrations
Saloon
Saloon is a PHP package for building API integrations with a clean, testable interface. It uses a plugin system for authentication, pagination, and caching.
Advantages: Modular, PSR-18 compliant, excellent testing support, and reusable SDKs.
Disadvantages: Newer, smaller community; learning curve for custom plugins.
When to use: When you have multiple external APIs or need robust testing.
Search
Laravel Scout (with Meilisearch)
Laravel Scout provides a simple driver-based approach to full-text search. Meilisearch is a fast, open-source search engine that works well with Scout.
Advantages: Easy integration, real-time indexing, typo-tolerant, and fast.
Disadvantages: Requires running a separate search service; not as powerful as Elasticsearch for complex queries.
When to use: For most B2B apps needing search; Meilisearch is a great balance of simplicity and performance.
Media Management
Spatie/laravel-medialibrary
Spatie/laravel-medialibrary associates files with Eloquent models, handles conversions (thumbnails), and provides responsive images.
Advantages: Rich API, image manipulation, easy file associations, and responsive images.
Disadvantages: Can be heavy if you only need simple file uploads.
When to use: When models need multiple file attachments with transformations.
Admin Panels
Laravel Nova
Laravel Nova is a premium admin panel that provides CRUD interfaces, metrics, and customization. It's not open-source but is the most polished option.
Advantages: Beautiful UI, rapid development, extensive features.
Disadvantages: Paid (€199 per site), can be opinionated.
When to use: When budget allows and you need a fast, professional admin panel.
Filament
Filament is a free, open-source admin panel built with Livewire and TALL stack. It offers forms, tables, notifications, and widgets.
Advantages: Free, modern, highly customizable, great developer experience.
Disadvantages: Requires Livewire knowledge; still evolving.
When to use: For most B2B SaaS apps needing a cost-effective, flexible admin panel.
Conclusion
Choosing the right libraries for your B2B SaaS can save months of development time. Start with Laravel Jetstream for auth, Spatie/permission for roles, and Filament for admin. Add Stancl/Tenancy for multi-tenancy, Cashier for billing, and Scout for search. Monitor with Telescope and audit with OwenIt. Each library has trade-offs, but these are battle-tested and well-supported. Evaluate your specific needs and don't hesitate to mix and match.
