New version of https://check-tls.akamai.io/ now checks H2, H3, and if the key exchange used PQC, in addition to TLS version and IPv6 support. It's a good way to test agents, thumbnailers, search engines, etc. Perhaps for a future version I'll replace the image.

Using https://check-tls.akamai.io/v1/tlsinfo.json will give some more raw data and can be usable for other types of agents.
