Short & clear

Symfony is an established open-source PHP framework with reusable components, a fixed release cycle and long-term support (LTS) versions – suited to long-lived enterprise applications, APIs and line-of-business portals. As a Symfony agency, Nano Concepts builds new applications, takes over and modernizes existing Symfony projects and connects them to your systems. Costs depend on scope (Starter from €2,500, Professional from €8,000, Enterprise individually quoted); the exact quote follows after the free initial consultation.

Symfony development with Nano Concepts

You usually need a Symfony agency in one of three situations: you are planning a new, complex PHP application, your existing Symfony project needs new developers, or the version in use is running out of maintenance. Symfony is well equipped for all three. The framework relies on clear architecture, dependency injection and loosely coupled components – qualities that pay off above all for software that stays in use for many years and is developed further by changing teams.

01

We like to use Symfony for applications with a lot of business logic: line-of-business portals, internal administration systems, interface backends and platforms with many roles and permissions. With Doctrine we model complex data structures, with API Platform we create documented REST and GraphQL APIs, and with Symfony Messenger demanding tasks run in the background. Because Shopware 6 is also built on Symfony, this knowledge is in demand for custom shop extensions as well. Whether Symfony or Laravel suits your project better, we advise neutrally – we work with both.

02

We take over existing Symfony projects in a structured way: code review, documentation of the architecture, safeguarding with tests – then comes further development or the upgrade. Symfony publishes versions on a fixed schedule and marks long-term support versions. Anyone moving from an old version such as 3.4 or 4.4 to a current LTS version benefits from the framework's clear deprecation strategy: outdated calls can be found in advance and replaced step by step. That turns a risky major overhaul into a plannable project.

FAQ

Frequently asked questions about Symfony development

That depends on whether we build from scratch, take over an existing project or carry out an upgrade. Smaller extensions and analyses are possible in the Starter package from €2,500, new applications and larger upgrades in the Professional package from €8,000, and extensive platforms in the Enterprise package with individual quoting. The exact quote follows after the free initial consultation.

Both are mature PHP frameworks; Laravel even uses some Symfony components. Laravel often allows a faster start with many ready-made building blocks, while Symfony plays to its strengths with very complex business logic, long lifespans and strict architectural requirements. We work with both and recommend what fits your project and your team.

Yes. We start with a code review, document architecture and dependencies and safeguard core workflows with tests. After that, you receive an assessment of the condition, risks and sensible next steps – only then do we move on to new features.

That depends on the version gap, the number of third-party packages and the test coverage. A move between consecutive LTS versions is often doable in a few weeks; larger jumps we plan in stages. After the analysis, you will receive a realistic schedule.

Symfony is an open-source PHP framework and at the same time a collection of reusable components that also power projects such as Laravel, Drupal or Shopware. It is used mainly for enterprise applications, APIs, portals and e-commerce solutions that are maintained for a long time.

After the free initial consultation and the analysis, we work in short stages with regular check-ins by video. The code lives in your or our Git repository, and every change goes through tests and review. You have fixed contacts and see progress in a test environment.
