Symfony

Symfony remains the reference PHP framework for business applications designed to last 10 years. Where other ecosystems prioritized velocity over maturity, Symfony built a reputation for stability, rigorous documentation, and predictable evolution. For French SMBs with a historical PHP stack, or for those maintaining critical applications, it's often the right tool.

1. 01

   Architecture in bounded contexts (light DDD), no mega-monolith

2. 02

   Systematic unit and functional tests (PHPUnit)

3. 03

   API Platform for headless or mobile needs

4. 04

   Automated CI/CD with security checks (Symfony Security Checker)

5. 05

   Technical documentation kept in sync with code (PHPDoc, OpenAPI)

• Is Symfony still a good choice?

  Yes, for the right use cases. Symfony remains the most mature PHP framework for business applications meant to last 10 years. Its stability, documentation and predictable LTS cycle make it a defensible choice against the constant JavaScript novelty. For a marketing site or simple e-commerce, it's overkill.
• What's the difference vs Laravel?

  Laravel prioritizes development velocity and convention-over-configuration. Symfony is more configurable, more modular, more enterprise-oriented and long-term. For a quick MVP, Laravel is often more efficient. For a complex business app built to last, Symfony provides a better foundation. Both are excellent PHP frameworks.
• Do I really need to move to the latest LTS?

  For security and maintainability, yes. Symfony LTS gets security updates for 3 years, and the community gradually drops older versions. Version upgrades are predictable: Symfony maintains excellent backward compatibility through its announced deprecations.
• How much does Symfony development or migration cost?

  For a new business application, expect €8,000 (MVP) to €40,000 (full multi-module app). For a migration from Symfony 4/5 to 7, expect €3,000 to €10,000 depending on size and accumulated technical debt. A prior audit clarifies the scope.
• Is API Platform worth it?

  For REST or GraphQL APIs, yes. API Platform built on Symfony has become a reference: automatic OpenAPI documentation generation, input validation, native format handling, fine-grained security. For a simple endpoint, it's oversized. For an API consumed by mobile, SPA frontend or partners, it's very efficient.
