  Studying the impact of new-physics models on low-energy observables
necessitates matching to effective field theories at the relevant mass
thresholds. We introduce the first public version of Matchete, a computer tool
for matching weakly-coupled models at one-loop order. It uses functional
methods to directly compute all matching contributions in a manifestly
gauge-covariant manner, while simplification methods eliminate redundant
operators from the output. We sketch the workings of the program and provide
examples of how to match simple Standard Model extensions. The package,
documentation, and example notebooks are publicly available at
https://gitlab.com/matchete/matchete.
