If you want an opensource / non AGPL licensed alternative for Kibana, Opensearch also includes a fork of Kibana in the form of Opensearch Dashboards.
Clickhouse not being Elastic/Opensearch based means they would need to reinvent that wheel in any case because Kibana cannot use Clickhouse for storage. So this isn't so much an alternative but an essential component to make Clickhouse useful. Since you can't use Kibana for that. From various accounts here; they seem to have done a decent job.
Of course the key strength of Kibana is that it builds on features that Elasticsearch has; like aggregations that are probably more limited in Clickhouse. Same with Opensearch Dashboards. It depends on your use case whether you actually need that of course.
One point of concern with Clickhouse is that, like Elastic, they require contributors to sign contributor agreements. This basically allows them to re-license the code base if they want to at some point. Which is of course what Elastic did several times now (they changed it back to AGPL a few weeks back). Like Elastic are well funded by VC money but still pre-IPO. Just saying that if you moved to Clickhouse because of the Elastic licensing debacle, you might just have moved that problem instead of solving it.
