  For the interpretation of past and future direct searches for dark matter
(DM) particles, it is important to be able to provide accurate predictions for
event rates and spectra under a variety of possible and viable assumptions in a
computationally efficient way. While there exists a few tools to compute DM
induced nuclear recoil spectra, 'obscura' is not limited to nuclear targets.
Instead its main focus lies on sub-GeV DM searches probing electron recoils
which typically requires methods from atomic and condensed matter physics. In
the context of sub-GeV DM searches, new ideas such as target materials or
detection techniques are being proposed regularly, and the theoretical
modelling of these are getting improved continuously. At the same time,
currently running experiments continue to publish their results and analyses,
setting increasingly strict bounds on the DM parameter space. In such a dynamic
field, 'obscura' can be an invaluable tool due to its high level of
adaptability and facilitate and accelerate the development of new, reliable
research software for the preparation of a DM discovery in the hopefully near
future.
