cloelike is a Python package that calculates statistical likelihoods for Euclid's main cosmological observations—weak lensing, galaxy clustering, and gravitational lensing between galaxies. It standardizes how researchers test competing cosmological models against Euclid data and is already used internally by the Euclid Consortium. The open release enables independent validation and reproducible analyses across the community.
