  During its first 10 years of orbital operations Swift dedicated approximately
11% of its observing time to blazars, carrying out more than 12,000
observations of ~1,600 different objects, for a total exposure time of over 25
million seconds. In this paper I briefly discuss the impact that Swift is
having on blazar multi-frequency and time-domain astrophysics, as well as how
it is contributing to the opening of the era of multi-messenger astronomy.
Finally, I present some preliminary results from a systematic analysis of a
very large number of Swift XRT observations of blazars. All the "science ready"
data products that are being generated by this project will be publicly
released. Specifically, deconvolved X-ray spectra and best fit spectral
parameters will be available through the ASDC "SED builder" tool
(https://tools.asdc.asi.it/SED) and by means of interactive tables
(http://www.asdc.asi.it/xrtspectra). Innovative data visualisation methods (see
e.g. http://youtu.be/nAZYcXcUGW8) are also being developed at ASDC to better
exploit this remarkable and rapidly growing data set.
