Need solutions for consuming Kafka messages in browser

Hello!

I'm looking for opensource solutions for consuming Kafka messages in
browser.
I found to interesting articles
1.
https://www.confluent.io/blog/consuming-messages-out-of-apache-kafka-in-a-browser/
2.https://ably.com/topic/websockets-kafka

Unfortunately:
- the first is from 2019 and does not provide any reference to solution and
a github repository.
- the second one is a proprietary solution of Ably.

Can you please advice what open source solutions are using for consuming
Kafka messages in browser?

Thank you,
Florin
