Recent advances in NLP and information retrieval have given rise to a diverse
set of question answering tasks that are of different formats (e.g.,
extractive, abstractive), require different model architectures (e.g.,
generative, discriminative), and setups (e.g., with or without retrieval).
Despite having a large number of powerful, specialized QA pipelines (which we
refer to as Skills) that consider a single domain, model or setup, there exists
no framework where users can easily explore and compare such pipelines and can
extend them according to their needs. To address this issue, we present
UKP-SQUARE, an extensible online QA platform for researchers which allows users
to query and analyze a large collection of modern Skills via a user-friendly
web interface and integrated behavioural tests. In addition, QA researchers can
develop, manage, and share their custom Skills using our microservices that
support a wide range of models (Transformers, Adapters, ONNX), datastores and
retrieval techniques (e.g., sparse and dense). UKP-SQUARE is available on
