Two codes for integrating the secular equations of motions for the three-body problem, including the quadrupole and octupole terms (see Tremaine+2009, Petrovich2015 and Liu+2015)
Also includes relativistic terms for the inner binary, including:
----1pN Pericenter precession (ala Ford+2000)
----Gravitational Wave emission (ala Blaes+2002)
----Spin-Orbit coupling (ala me, following Barker and O'Connell 1975)
----Spin-Spin coupling (same)
You are welcome to use either code in any way you like, though we ask that if you use any results from it in a paper that you cite Rodriguez and Antonini (2018, https://arxiv.org/abs/1805.08212) and Antonini et al (2017, https://arxiv.org/abs/1711.07142)
