A query language designed with speed, simplicity and scalability in mind

  • We significantly simplify communication in your application
  • Implementing a data graph allows replacing code in an API interface, communication with the database, or between microservices
  • You can optimize your project by providing code to increase development in applications significantly

Why GraphQL?

Choose GraphQL for web and 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.

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.
