Comparison: FlexiCapture Engine vs. FlexiCapture Server

FlexiCapture Engine
9.x, 10, 11
Technology & Features, Comparisons
General Features, Integration
  • This article compares the features and differences of ABBYY FlexiCapture Engine (SDK) and ABBYY FlexiCapture Server (Solution, with database & Web API). Both products can be used for high volume document processing within your own application/service or on a back-end server.
  • The comparison focuses on server based processing with both products using the “SDK API” v.s the “Web Service API of the server”.
  • FlexiCapture Engine can of course also be integrated in standalone applications, but therefore a different set of features and business scenarios should be compared.

Development & Setup

  • Users of both products, FlexiCapture Engine and FlexiCapture Server, use the same tool for developing document definitions and document templates: FlexiLayout Studio
  • The ready-to-use application FlexiCapture Server is only sold via certified, trained VARs and channel partners. The SDK FlexiCapture Engine needs further programming and is licensed as technology directly from ABBYY.
  • FlexiCapture Engine is delivered together with the software FlexiCapture Standalone, which contains the FlexiLayout Studio for template development. Developers can use the application FlexiCapture Standalone for creation and testing of templates but are not allowed to re-sell this product.
  • Training on the core FlexiLayout technology is highly recommended for FlexiCapture Engine (Training Overview)
  • ABBYY offers professional services and support to secure the success of your projects, no matter if you decide to integrate the FlexiCapture SDK or deploy the ready-to-use FlexiCapture Server.
