| E-commerce & OMS | Order management, marketplace integrations, stock and returns in one flow. |
| Logistics | Shipping, labels and parcel tracking across couriers. |
| Custom development | Business applications designed around the way your team works. |
| Integrations | Marketplaces, shops, couriers, invoicing and accounting systems. |
| Long-term support | We maintain what we build — updates, monitoring and new features. |
sellero.org The operating system for e-commerce sales. Orders, messages and stock from every marketplace in one panel — from purchase to shipment and a calculated margin. |
deliverio.org Every courier. One API. Create shipments, generate labels and track parcels across InPost, DHL, DPD, GLS and more — synchronously or asynchronously. |
We build our products on open source and give back what we can. Everything below is MIT-licensed and installable with Composer.
Filament Enhanced Charts Apache ECharts for Filament panels — from sankeys to calendar heatmaps, every chart built from typed PHP objects. |
Filament Presence Live "who's on this page" avatars for Filament panels, with a link to the exact view a teammate has open. |
Filament Saved Views Save a table exactly as you left it — filters, search, sort, grouping and columns — and reopen it in one click. |
Filament Multi-Source Upload A drop-in FileUpload that also imports from a URL — fetched safely on the server and stored like any upload.
|
Filament Passkeys Multi-factor authentication with WebAuthn passkeys, powered by laravel/passkeys.
|
Filament Turnstile Cloudflare Turnstile for your panel — register once to protect login, and optionally registration and password reset. |
Filament Translatable Multilingual content in Filament — translatable fields in a tabbed interface, for any number of locales. |
Filament PHPStan Macros Teaches PHPStan and Larastan the macros registered on Filament components, so the code chained after them is checked again. |
Filament User Profile A user profile page for Filament panels, with every section replaceable, removable or extendable with your own components. |
Filament Comments Comments on any record — rich text or Markdown, mentions, quoting, shareable deep links and pagination. |
Laravel True Modular Makes a modular monolith explicit, deterministic and analyzable — topological service provider ordering and an enhanced application lifecycle. |
Laravel True Modular PHPStan Enforces module boundaries and types the relations modules add at runtime — statically, with zero configuration. |
Laravel True Modular Health Lets each module declare its own health checks, aggregated with architecture diagnostics in module:doctor.
|
Laravel Access Control Enum-based permissions and voters for modular Laravel applications — every module brings its own permission logic. |
Laravel LTree The PostgreSQL ltree extension through an expressive Laravel API, for hierarchies and tree queries.
|
Address Splitter Splits an address into street, building number and apartment number, with formats for 29 European countries. |
