README

Laravel Truss is a live database structure viewer. It scans your live schema and renders it as a scrollable, zoomable ER diagram right inside your app, so you can see how the tables actually connect without opening a DB client. It reads structure only (tables, columns, keys, indexes); row data is never queried or exposed.

Try the live demo to pan, zoom, focus, and export a sample schema in your browser, no install needed.

Features

• Live ER diagram of your database, rendered with Mermaid.
• Focus mode: a table and its foreign-key neighbours, centred and highlighted.
• Filter by table name, and toggle native types against Laravel-style labels.
• Map-style pan and zoom, with auto-fit and a Fit button.
• Light and dark "blueprint" theme.
• Self-contained: Mermaid and fonts are vendored and served from the package, so it works offline and under a strict Content-Security-Policy (no CDN).
• Cached snapshot, rebuilt automatically after migrations.

• Installation
• Quick start
• Authorization
• Configuration reference

Installation

For local use, install Truss as a dev dependency:

composer require albertoarena/laravel-truss --dev

To run Truss gated on staging or production, install it as a regular dependency instead. Dev dependencies are excluded from composer install --no-dev builds, so a --dev install never reaches a production deploy and /truss returns 404 there:

composer require albertoarena/laravel-truss

Requires PHP 8.3+ and Laravel 12+. The service provider is auto-discovered, so there is nothing to publish to get started.

Quick start

By default Truss is enabled in the local environment only. Start your app and visit:

/truss

To use Truss in a non-local environment you must both enable it and authorize the viewers. See Authorization.

Security

Truss exposes structure only and never queries row data. Access is protected by the fixed viewTruss gate. If you discover a security issue, please email [e-mail] rather than opening a public issue.
