[Takeaways](#takeaways) Why Multi-Panel Filament Gets Painful at Scale ---------------------------------------------- Filament's panel system is elegant for a single admin area. The moment you add a customer portal, a vendor dashboard, and an internal ops panel — each with its own auth guard, middleware, and data scope — the default conventions start to fight you. Add tables with 500k+ rows and you have a performance problem on top of an architecture problem. This article addresses both. --- Registering Multiple Panels Without Coupling Them ------------------------------------------------- Each panel lives in its own `PanelProvider`. Keep them in `app/Panels/` and register them individually in `bootstrap/providers.php`. ```php // app/Panels/VendorPanelProvider.php use Filament\Panel; use Filament\PanelProvider; class VendorPanelProvider extends PanelProvider { public function panel(Panel $panel): Panel { return $panel ->id('vendor') ->path('vendor') ->authGuard('vendor') ->login() ->middleware([ EncryptCookies::class, StartSession::class, VendorTenantMiddleware::class, // your custom scope ]) ->authMiddleware([Authenticate::class]) ->discoverResources( in: app_path('Filament/Vendor/Resources'), for: 'App\\Filament\\Vendor\\Resources' ); } } ``` The `authGuard('vendor')` call wires Filament's internal auth checks to your custom guard defined in `config/auth.php`. No shared session bleed between panels. ### Per-Panel Middleware for Tenant Scoping Don't rely on global middleware for tenant resolution when panels have different scoping rules. A dedicated middleware per panel keeps the logic explicit: ```php class VendorTenantMiddleware { public function handle(Request $request, Closure $next): Response { $vendor = auth('vendor')->user()?->vendor; if (! $vendor) { abort(403); } app()->instance(CurrentVendor::class, $vendor); return $next($request); } } ``` Bind `CurrentVendor` as a scoped singleton so every Eloquent query in that request can resolve it without a second DB hit. --- Table Query Tuning: Where Filament Tables Actually Slow Down ------------------------------------------------------------ Filament's `Table` component calls `->paginate()` on your base query. The base query is built in `getTableQuery()` on the resource. This is where most N+1 and missing-index problems live. ### Always Eager-Load in `getTableQuery` ```php public static function getTableQuery(): Builder { return parent::getTableQuery() ->with(['vendor', 'status', 'latestShipment']) ->withCount('lineItems'); } ``` Filament will not automatically eager-load relationships referenced in columns. If your `TextColumn` calls `->relationship('vendor', 'name')`, Filament does add a join internally — but for anything more complex, explicit `with()` is safer and more predictable. ### Deferring Expensive Counts Avoid `->withCount()` on large tables when the count isn't displayed by default. Use a `TextColumn` with `->default('-')` and `->toggleable(isToggledHiddenByDefault: true)` so the count only loads when the user opts in: ```php TextColumn::make('line_items_count') ->counts('lineItems') ->label('Lines') ->toggleable(isToggledHiddenByDefault: true), ``` ### Scoping the Base Query for Authorization For row-level security, apply the scope directly in `getTableQuery()` rather than a global scope. Global scopes affect every query in the process — dangerous under Octane. ```php public static function getTableQuery(): Builder { $vendor = app(CurrentVendor::class); return parent::getTableQuery() ->whereBelongsTo($vendor) ->with(['status']); } ``` ### Index Your Filter Columns Filament table filters translate to `WHERE` clauses. If your `SelectFilter` targets `status` or `created_at`, those columns need indexes. Use `EXPLAIN ANALYZE` in PostgreSQL or `EXPLAIN` in MySQL to confirm the planner is using them. ```sql CREATE INDEX idx_orders_vendor_status ON orders (vendor_id, status); ``` A composite index on `(vendor_id, status)` covers the common case of scoped + filtered queries in one scan. --- Takeaways --------- - Register each panel in its own `PanelProvider` with a dedicated `authGuard` and middleware stack — never share session state across panels. - Inject tenant context via a scoped singleton bound in per-panel middleware, not a global scope. - Always call `->with()` explicitly in `getTableQuery()`; don't rely on Filament's relationship column resolution for complex graphs. - Hide expensive aggregate columns behind `->toggleable(isToggledHiddenByDefault: true)` to avoid counting millions of rows on every page load. - Add composite indexes that match your most common `(tenant_id, filter_column)` query patterns. - [filament](https://www.msaied.com/public/articles?search=filament) - [laravel](https://www.msaied.com/public/articles?search=laravel) - [multi-panel](https://www.msaied.com/public/articles?search=multi-panel) - [performance](https://www.msaied.com/public/articles?search=performance) Frequently asked questions --------------------------- Can two Filament panels share the same auth guard?Technically yes, but it creates session and authorization ambiguity. Each panel should use a distinct guard so Filament's internal auth checks, redirects, and middleware operate independently without interfering with each other. Does calling ->with() in getTableQuery() conflict with Filament's built-in relationship column loading?No. Filament's relationship columns add their own eager loads on top of your base query. Explicit ->with() calls in getTableQuery() are additive and give you full control over which relationships are loaded and how. How do I prevent a global Eloquent scope from leaking across panels under Octane?Avoid global scopes for per-request tenant filtering entirely. Instead, apply the scope directly in getTableQuery() using the scoped singleton bound in your panel's middleware. This keeps the scope request-local and safe under Octane's persistent worker model. ![Mohamed Said](https://cdn.msaied.com/01M22N44A70A5MC2S599JP0MPH.webp)About the author ---------------- [Mohamed Said](https://www.msaied.com/public#person)Senior Backend Engineer specializing in Laravel, scalable SaaS platforms, APIs, and cloud infrastructure.
