Our company uses https://github.com/obsidiandynamics/kafdrop it's FOSS. It can also handle AVRO and PROTOBUF messages.

Does your company use both Avro and Protobuf for message serialization? Most places tend to standardize with one or the other and I’m wondering if there is a use case for both.

We use Avro only, just wanted to mention that Protobuf is also supported.

CMAK, AKHQ, Kafdrop, Kowl, Conduktor, Kafkatool etc.... why are there so many attempts to build a kafka UI? Does each one have its own use case? I'd think that something as large as "Kafka" in the software ecosystem would have a goto defacto standard UI for managing it.

There are also many different UIs for kubernetes.

I was looking for something like this about a year ago but no open source solution existed. Thank you!

you must not have looked for long, most of the other OSS tools mentioned in this thread exist for several years already.

Earlier quoted context omitted.

Slightly off topic but for the shell in the example what did they export PS1 to get the nice looking solid background color for the host name and current working directory?

Looks like some type of powerline plugin for their shell https://github.com/b-ryan/powerline-shell

Yep, that's powerline (or an alternative inspired by) with an improperly-patched font (which is why it's got the box characters).

These ones (stolen from another comment)?

Maybe if they had been given better, more descriptive, names they'd have been easier to fit

Having looked into a couple of these, it seems like they each have their own sort of focus, which makes sense. From my own experience, and talking to other engineers, companies use kafka for: an http replacement that lets subscribers have down time, a way to record and replay time series data, a tool for buffering to some async path, or general pub-sub event bus. Sometimes all of these at once! Each one has it's only operational patterns, so having UIs that focus on these patterns sorta clicks with me.

That said, it's been a while since kafka gained popularity, so it's surprising we've not seen any coalesce into a main contender.

Some of these had more descriptive names, but the apache software foundation doesn't allow names with "Kafka" as part of the name because it's a protected trademark apparently.
