The BHPToolkit is aiming to provides codes, data and tutorial for black hole perturbation theory calculations. Its aims are somewhat similar to the Einstein Toolkit and with the Self-Force 1D code there is science overlap.

Their website is https://bhptoolkit.org/ and it might be good to periodically check in with them. Eg for their most recent tutorial and workshop in Prague (https://www.youtube.com/channel/UCuQQbp9Buq-R3da4zASTFfw).
