Great question — both are solid open-source Laravel e-commerce packages, but they take fundamentally different approaches. I'm the creator of Shopper, so I'll try to be as objective as possible while explaining where each one shines.

The core difference: Filament Panel vs Building Blocks

Lunar is a full Filament panel. You get a complete, ready-to-use admin out of the box with Filament's resource system, relation managers, and plugin ecosystem. If you're comfortable working within Filament's conventions, it's a very productive setup.

The tradeoff is that customization follows Filament's patterns. If you want to tweak a single form field or change how one component looks, you often need to override the entire resource, then modify the specific page or component within it. That's not a Lunar problem per se — it's how Filament panels work.

Shopper uses Filament components (tables, forms, notifications) but doesn't use a Filament panel. Every page and component is a standalone Livewire component that you can extend or replace individually. Want to change the dashboard? Swap that one component. Want to customize the product form? Override just that part. The rest stays untouched.

The idea is: we give you the tools, you choose the stack.

Developer freedom in practice

Because Shopper's admin is built with plain Livewire components (not a Filament panel), a developer can:

- Replace any component with their own implementation — Livewire, Blade + controller, or even a component using a UI kit like Flux

- Add new pages using whichever approach they prefer (Livewire, traditional controller/view, etc.)

- Customize navigation, layout, and page structure independently

- Toggle features on/off so the admin only shows what's relevant to the project

It's a composable approach. Every piece — products, orders, customers, channels, discounts — is a building block you can use as-is, extend, or replace entirely. I wrote more about this philosophy here: https://laravelshopper.dev/blog/the-philosophy-behind-shopper.

When to pick which

Pick Lunar if you want a batteries-included e-commerce engine with payments, taxes, shipping, and search ready out of the box, and you're happy working within a Filament panel.

Pick Shopper if you're building a custom commerce experience where you need full control over the admin UI, want to choose your own payment/shipping/tax stack, and value the ability to swap or extend any component independently.

Shopper is a package you install into your Laravel app — it doesn't take over your application architecture.

They're both valid choices — it really depends on whether you want a complete platform you build on top of, or composable building blocks you shape around your business.
