Why GraphQL?

Choose GraphQL for web & mobile app development

GraphQL helps tackle over-complexity, which is a common problem in applications that scale. As a query language for your API it simplifies the project and lets you stay nimble without ever hampering scalability and robustness. By design, it minimizes the amount of data on the wire, contributing to a snappy user experience.



GraphQL provides a single source of data, streamlines communication between front and back-end and doesn’t require end-points for every use-case.


Front-end can ask for exact data when it needs it and no redundant data is ever passed around. It results in a much snappier user experience.


GraphQL is perfect for microservice-based architecture and makes it growth-ready. It allows you to extend your project, without increasing technological debt.

What do clients think about working with Vazco?

I had my doubts about outsourcing some key development areas outside our company; however, people at Vazco have proven my doubts wrong. The team at Vazco has shown real commitment and product ownership at such a level that it would be hard to build even internally and definitely rare when outsourced. They are also really nice people and fun to work with.

Jonne Castrén

Geert Peter de Oude

CEO at Onyx

We’re very impressed with Vazco's work pace, communication, and quality. At first, we didn't prepare a sufficiently extensive backlog for the team, as we were not expecting the development pace to be so fast!

Harrison Hunter

CTO at MaestroQA

Introduction of a 3D Configurator, transfer to a new e-commerce platform, and other planned changes we did, increased our conversion rate by approx. 100%. [...] They advised us how to efficiently move into a direction we were aiming at - becoming the most digital furniture retailer in Europe.

Frequently asked questions


Here are answers to some of the most common questions asked by our Clients about the GraphQL technology.

GraphQL is a query language for API.

It creates a common language for communication between clients and servers. The central part of the solution is a GraphQL schema that describes your data's shape so that both parties can communicate more efficiently.

For many years, the gold standards for API data exchange was REST and SOAP. GraphQL gets the best of two worlds and provides a lightweight and fast API that is easy to use, but at the same time, it's strictly typed and secure.

It allows you to define the shape of your business domain data - the schema - and query and retrieve only whats needed. Simultaneously, it's easy and fun to work with, so adoption among developers was very rapid.

Besides the obvious advantages like lowering bandwidth usage by preventing under- and over-fetching or great tooling that makes developers more productive, the biggest reason hides in plain sight.

By taking the SDL-first approach, you put your business use cases in the heart of your IT system, not the other way around. As your app grows, instead of looking for workaround and hacks, you can shape the API (which is the backbone of every IT system) for your ever-changing business needs.

Of course! All three are just API communication standards and can be used interchangeably. There are no limitations on the transferred data or its size, so you can use GraphQL at all times.

Definitely! There are no limitations for the underlying technologies used to retrieve the data exposed via a GraphQL API. If needed, you can use multiple database systems as well as other APIs of all sorts - GraphQL, REST, and SOAP.

There are three types of operations in GraphQL: queries, subscriptions, and mutations. The first two are retrieving the data - once and “as it changes” respectively. The third type is meant to be used for operations that create, change, or remove the data.

No, but it is not slower either. Both have their performance ups and downs. While REST will suffer from over-and under-fetching, GraphQL responses are harder to cache. Of course, all problems are addressable but require additional implementation.
