I'm one of the authors of Kowl (github.com/cloudhut/kowl) and compared to the listed solution I think it stands out by it's superior UI/UX. When deserializing messages you don't have to select Codecs, it automatically detects the appropriate codec! The UI does not overwhelm you with a lot of information, it has a proper JSON viewer (Protobuf, Avro, XML messages are rendered as JSON as well). It is also lightweight (written in Go and React) and easy to run (docker container without dependencies).
Last but not least: It's open source and therefore it does not have any restrictions like a user limitation, or a web version which has to be paid for. Support is also available via Discord or GitHub :-).
We do have a business version which offers additional features like audit logging in Kowl, Authentication & Authorization around Kowl etc.. These features are mostly relevant for larger organizations where Kowl is used by hundreds of users.
