  We describe ColliderBit, a new code for the calculation of high energy
collider observables in theories of physics beyond the Standard Model (BSM).
ColliderBit features a generic interface to BSM models, a unique parallelised
Monte Carlo event generation scheme suitable for large-scale supercomputer
applications, and a number of LHC analyses, covering a reasonable range of the
BSM signatures currently sought by ATLAS and CMS. ColliderBit also calculates
likelihoods for Higgs sector observables, and LEP searches for BSM particles.
These features are provided by a combination of new code unique to ColliderBit,
and interfaces to existing state-of-the-art public codes. ColliderBit is both
an important part of the GAMBIT framework for BSM inference, and a standalone
tool for efficiently applying collider constraints to theories of new physics.
