Choosing a Backend: Supabase, Laravel or a Custom PHP API?

There is no single best backend

Over several projects we have used three different backend approaches: Supabase for an HR management system, Laravel with a relational database for a school portal and a fintech service, and small custom PHP APIs with MySQL for a group of healthcare websites. Each choice was deliberate. Here is how we think about the trade-offs.

Supabase: speed and built-in features

Supabase gives you a Postgres database, authentication, file storage and serverless functions out of the box. For our HR system this was a good fit. Roles, row-level security and audit logs could be expressed directly in the database, and the React front end could talk to it through typed queries. You get to a working product quickly and security rules live next to the data.

• Best when you need rapid development and standard features such as sign-in and file storage.
• Row-level security is powerful, but policies must be written carefully and tested.
• Custom functions need to verify the caller themselves, so you must be disciplined.
• You depend on a hosted service and its pricing.

Laravel: structure for complex business rules

Laravel is a full-featured PHP framework. For the school portal and the fintech platform, we needed rich workflows: results computation, fee records, WhatsApp command handling, payments and role-based dashboards. Laravel's structure, migrations, validation and testing tools keep a large codebase organised over years. It also runs well on standard hosting.

• Best for complex business logic and long-lived systems.
• Rich ecosystem and strong conventions help new developers join quickly.
• Requires a PHP-capable host and a deployment routine.
• Server-rendered pages are fast and simple when you do not need a heavy front end.

Plain PHP and MySQL: small, cheap and portable

For the group of healthcare websites, each company needed its own small backend for contact forms, bookings, staff accounts and content. A tiny PHP API with a MySQL database is inexpensive, runs on almost any shared or cPanel hosting, and is easy to hand over. We added the essentials ourselves: hashed sessions, anti-forgery tokens, rate limiting, honeypots, audit logs and role checks.

• Best for small, well-defined needs on tight budgets or standard hosting.
• You must build security basics deliberately because there is no framework to supply them.
• Keep the surface small and test it end to end.

How to choose

Ask these questions:

• How complex are the business rules, and how long will the system live?
• Do you need real-time features, sign-in or file storage quickly?
• Where will it be hosted, and who will maintain it?
• What is the budget, and who will own the data and the code?
• What skills does the team that will maintain it already have?

Our rule of thumb

Use a managed backend such as Supabase when speed and built-in features matter most. Choose Laravel when business logic is rich and the system must last. Use a small custom API when needs are simple and hosting is basic. Whatever you choose, insist on good security practice, backups and documentation.
