Big time for a product!

You have an idea, we have the expertise to build it

We know that building a product is a long-term game. We are here to help you on this journey! We develop tailor-made software built on top of Ruby on Rails and React. 


We can build your web application and serve mobile devices at the same time

Most of the applications we work on have a solid server side business logic. Keeping logic at your server brings safety into the table. We can also serve mobile devices through API or mobile web. This setup works great in practice and can scale to millions.

Instant feedback by an agile team

We will minimise your business risks by letting you see progressing features any time.

Integrations made easy

We can integrate to APIs to extend your abilities. And you can also provide your own APIs for other businesses with ease.


Tests and processes for safety

Your application will have an extended test suite and a CI/CD pipeline to ensure that everything is deployed as planned.

Hosting stacks, where products live

Clouds we deploy to every week

Our clients come with tools they like to work with. We respect their choiches.

Words from our CTO, Attila Juhász

We understand the language of business and IT at the same time. This can be a real advantage for you.

We value a good connection with our partners. It means that we try to achieve your goals not just clear off the task list. We also give honest feedback, so you can plan and change your actions in case anything comes up during development which could disturb your vision.

Case study / UNHCR

It was a pleasure to work with the UNHCR ERM team. We enjoyed their deep understanding of the application and the data they operate with. Their mission also motivated us to make our best.

Reflections on the development / maintainance journey

What our partners say

Alongside green field development, we have been happily upgraded Rails codebases frome Rails 2 to Rails 7 and made further development possible.

We have been working with App Maintainers for almost a decade - and it's not without reason. They have received even our craziest ideas with such care, creativity, and patient professionalism that we almost consider them as members of our own team.

Gergely Lukácsházi

CEO at UrbanDialog

The App maintainers team, have worked with UNHCR on a long term project (8 years) – The Risk Register Tool. It is a simple yet an extremely efficient tool in capturing the risk information for country operations. This tool serves its purpose very well and it is highly appreciated by the colleagues in fields due to its simplicity. The quality of software development service delivered by App Maintainers is instrumental in the success of our application. App Maintainers are dedicated, highly professional and it has been a pleasure to work with them. They were extremely responsive when we faced high severity issues and ensured it is solved in time. They have proposed innovative solutions to some of change requests which have elevated the quality of our application.
