FilamentPHP Development
13Node is a small Laravel studio based in Spain. We build the part of your product your team lives in every day: admin panels, internal tools and multi-tenant back offices, built on FilamentPHP and designed around how your business actually works.
We also publish Filament plugins, so we know the framework from the inside, not just from the docs. When you work with us, you talk to the developer writing your code.
What we build with Filament
Admin panels and back offices
Resources, relation managers, custom pages, dashboards and widgets. Roles and permissions that match your organisation, not a generic template.
Multi-tenant SaaS panels
Tenant-aware panels where every company sees only its own data. We run our own multi-tenant platform on Laravel and Filament, covering HR, time tracking, invoicing and lead management.
Custom fields and plugins
When the form or table component you need does not exist, we write it: custom fields, columns, actions and full plugins, packaged so you can reuse them across projects.
Upgrades between Filament versions
Stuck on an older major version? We upgrade Filament panels and the Laravel app underneath, fix what the upgrade breaks and leave you on a supported release.
Migrations to Filament
Moving from Laravel Nova, a hand-rolled admin or a legacy PHP back office. We migrate in phases so your team never loses access to the tools it depends on.
Integrations
Connecting your panel to payment gateways, ERPs, invoicing tools and third-party APIs, with queued jobs and clear logs when something fails.
Our open-source Filament plugin
Filament Mermaid Field
A custom field to write Mermaid diagrams inside your Filament forms and see them render as you type. It is MIT-licensed and available on Packagist.
- Integrated editor with real-time Mermaid rendering
- Interactive zoom and pan
- Follows Filament’s light and dark themes
- English and Spanish translations bundled
- Filament 5 on Laravel 11, 12 and 13, with a 2.x branch for Filament 3
composer require trecenode/filament-mermaid-fieldSource on GitHub, package on Packagist and documentation on the plugin page.
How we work
A call about the problem
One hour, no cost. We look at what you have, what your team needs and whether Filament is the right fit. Sometimes it is not, and we will say so.
Written scope and fixed price
What we will build, what is out of scope and what it costs. Changes along the way are quoted separately, never added silently to the bill.
Deliveries every two or three weeks
Each phase ends with something you can log into and use, so you correct course early, while it is still cheap to do so.
Handover and support
The repository is yours, with documentation. Ongoing support is available as prepaid hour packs, or not at all if your own team takes over.
Why a small studio
No account managers relaying messages to a team you never meet. You talk to the person writing the code, and decisions take a message, not a meeting. We have been building for the web since 2011, and today most of our custom work runs on Laravel and Filament.
Where we work from
Madrid and Tenerife, on Central European Time, with working hours that overlap the UK and the rest of Europe. We work in English, Spanish, Portuguese and Japanese. More of our work in projects and custom applications.
