Symfony web development

Why do we love Symfony PHP framework?

Symfony is a versatile, reliable and mature PHP framework. Used to build web products of all kinds. From small websites to high-performance complex web applications. Symfony development is a great choice for a startup MVP app, but also a robust and reliable solution for an enterprise-level application. Symfony is also one of the most popular frameworks in the open-source community. Community, that is always ready to share knowledge, expertise and guidelines.

And of course, we love Symfony because we grew up together. Need help with Symfony? Hire Symfony developers who know it by heart!

Quotes
Symfony has everything I expect from a modern framework. It is fast, flexible and provides reusable components. Supported by a great open-source community that builds the future of Symfony development. I appreciate it as a CTO and as a Symfony developer myself.

  • Bulb
    Innovation

    Symfony contributors seek continuous improvement in the productivity of PHP developers. Symfony community do not hesitate to innovate by seeking out ideas elsewhere and adapting to the PHP world. Like a dependency injection from the Java world or a “web debug toolbar” taken from other frameworks.

  • Diamond
    Resources

    With Symfony, you will never be left on your own. You will find many publications dedicated to the Symfony framework as well as open-source projects and tutorials. With community support (forums, mailing lists, stack overflow) and company support (training, consulting), you will always find the right answers.

  • Group of dots
    Interoperability

    Symfony was created with interoperability at heart and the idea of "Don’t lock yourself up within Symfony!". It is a complete PHP framework but it also allows you to use certain pieces of its software building blocks. Actually, is so interoperable that, it uses at its core third-party software itself.

  • Upgrade
    Lasting support

    In 2025, Symfony will celebrate its 20th anniversary. Had you chosen Symfony app development for your product two decades ago, it would likely still be growing and improving. Amidst the ever-changing landscape of web development, characterized by the rapid emergence and disappearance of tools and frequent framework updates, Symfony stands out as a stabilizing force. It provides long-term support (LTS) versions, ensuring 3 years of maintenance and 4 years of security fixes - a level of commitment rarely found elsewhere.

  • Diamond
    Stability and predictability

    Modern web development is considered a very fast-paced and ever-changing environment. This means that you have to constantly upgrade your tech stack to keep it up to date with the versions that are still maintained. But Symfony is different! With its just 6 major versions in 20 years! While being actively developed, it does not introduce any revolutions. It evolves, gradually adapting what proved to work well in other frameworks. Stability and ease of keeping up to date is a huge advantage of the symfony application development.
