Continuous Transformation Platform

LeanIX is a Software-as-a-Service helping organization to analyze and plan their Enterprise Architecture in order to build better products and succeed in digital transformation. The core of the product is an extendable inventory that comes with a browser-based user interface and a smartphone app. This documentation supports people for platform-related information and also for people with technical background with the following topics:


The LeanIX platform is accessible through our web app, mobile apps, and our REST API and comes with many features crucial to organizations, such as:

  • Inventory about used Applications, Technologies, Projects, ...
  • Visualization of structures and dependencies
  • Collaboration between experts and stakeholders
  • Implementation of custom workflows (Surveys)
  • Storage of real-time Business & IT Metrics
  • Integration with other IT Management tools (e.g. BPM)
  • Enterprise grade Security (e.g. SSO)


LeanIX provides different services which can be used via the available APIs. All APIs can be used with a common authentication. LeanIX fits well into an ecosystem of modern tools to manage the company's IT. Use our APIs or our built-in integrations to integrate LeanIX into your own environment.


Swagger API Documentation

All available REST APIs are documented using Swagger. Based on the Swagger definition we provide a web frontend for each API which shows the documentation and allows to try out the methods directly from the web browser. We at LeanIX love swagger.



In addition to our REST API, we offer a GraphQL API to read and write the Inventory. Within our web UI we have integrated the in-browser IDE GraphiQL to write and execute GraphQL queries. It also allows you to explore the data model of the Inventory.
