How does it compare to Plausible, Matomo and Umami

Thank you for the question.

Those platforms seem to be web analytics platforms, purpose built to track and analyze data from visitors to your web site.

Delve, on the other hand, concentrates on ingesting large quantities of structured, semi-structured and unstructured text based data. Think log files, csv, json, xml, item descriptions, etc.

The closest product to Delve would be something like Splunk or ELK.

I would say Delve is easier to get started with than Splunk or ELK, but actually offers more control since you can easily write your own search commands and field extractions. Also, role based access control is implemented to give fine-grained access to data.

Also configuration is all in one place, backend databases are configurable (sqlite, postgres, MySQL and any other database that works with the django ORM) and more.

Please let me know if you'd like any more details.
