  New Physics model building requires a vast number of cross-checks against
available experimental results. In particular, new neutral, colorless, spin-1
bosons $Z'$, can be found in many models. We introduce in this work a new
easy-to-use software Z'-explorer which probes $Z'$ models to all available
decay channels at LHC. This program scrutinizes the parameter space of the
model to determine which part is still allowed, which is to be shortly
explored, and which channel is the most sensitive in each region of parameter
space. User does not need to implement the model nor run any Monte Carlo
simulation, but instead just needs to use the $Z'$ mass and its couplings to
Standard Model particles. We describe Z'-explorer backend and provide
instructions to use it from its frontend, while applying it to a variety of
$Z'$ models. In particular we show Z'-explorer application and utility in a
sequential Standard Model, a B-L $Z'$ and a simplified two-sector or
Warped/Composite model. The output of the program condenses the phenomenology
of the model features, the experimental techniques and the search strategies in
each channel in an enriching outcome. We find that compelling add-ons to the
software would be to include correlation between decay channels, low-energy
physics results, and Dark Matter searches. The software is open-source ready to
use, and available for modifications, improvements and updates by the
community.
