I created a complementary resource, https://badtls.io https://badtls.io to allow for automated testing of TLS client libraries. It uses its own self-gendered CA root to allow for generating certificates that exhibit different edge case conditions. A few practical differences are that badtls.io is designed to be easy to run locally and having simple Python scripts to generate new keys and certs. For my TLS libraries I utilize both badssl.com and badtls.io to provide more diverse coverage.
