The dcupl stack

The dcupl ecosystem is a robust suite of tools designed to streamline every aspect of data management and web development. At its core is the dcupl SDK, empowering developers with versatile functionalities. The dcupl Console takes charge of data, project, and process administration, offering a centralized hub for seamless control.

For rapid web development, dcupl components provide an agile solution, ensuring efficiency in creating dynamic web applications. dcupl's REST APIs excel in crafting out-of-the-box APIs that mirror the functionality of the dcupl SDK - but operate on the server side. Additionally, dcupl Workflows empower users to establish efficient data pipelines, enhancing overall workflow management.

dcupl Playground

  • Check out the SDK in action.
  • The example loads and prepares 44k fashion products + the model definitions from our CDN
  • queries, facets, aggregations and more in your browser - no backend involved.
  • go to console.dcupl.com and join the demo for free


Depending on your use case there are multiple possible architectures. The main points to consider are:

  • Availability: Do you have an production ready API or do you need to work with an static export?
  • Security: Is the data securely available to the world wide web?
  • Freshness: How often does your data change?

Designed for Developers

Created by developers and battle tested in real projects, ensuring an exceptional development experience & performance.

Take back Control

Provide your own data, define your perfect data model and keep your business logic in your front-end project.

Decoupled Development

Develop independently from back-end systems, minimizing dependencies and enhancing agility.


decoupled digital catalog, no direct connection to source system

high-performance filtering of complex data and huge data amounts

rolled out 50% faster, with dual-speed, decoupled from source systems

80% faster to complete the PoC and validate a “lighthouse idea”

dcupl takes away most of the dependencies that prevent our front-end team from working uninterrupted and being productive, like unfinished or constantly changing APIs. It provides a simple to use SDK, that handles a lot of the boilerplate code needed in every application!
