Summary: RGIsearch is a C++ program that searches for invariants of a user-defined set of renormalization group equations. Based on the general shape of the \(\beta\)-functions of quantum field theories, RGIsearch searches for several types of invariants that require different methods. Additionally, it supports the computation of invariants up to two-loop level. A manual for the program is given, including the settings and set-up of the program, as well as a test case.
