In 2022-Q1, I conducted a series of data-viz trials between Grow, PowerBI, Mode, trevor.io, GoodData, Klipfolio, Domo, Sisense, Knowi et al. The trials included my team members, but we were outnumbered (by design) by non-tech business users. The biggest surprise was how quickly Mode ("too inflexible & slow") was eliminated – I thought for sure they would be a finalist. We built the highest number of useful dashboards the fastest using Knowi – a clear win. After the trials, we migrated everything we made to Knowi, as we didn't try out any canned use cases, only real-world "need" cases. While we selected Knowi as a viz tool, I'm also happy we did so from a data engineering perspective. Knowi's architecture models data thoughtfully, which I'd credit for enabling a collection of elegant features. Like the ability to live-update the contents of a dataset incrementally via API. Or Knowi's ability to query a source, returning a dataset that you can immediately re-query where it becomes a transformed/derived data-set... which it can hold on to for you, or persist in a different destination, or Knowi can even rewrite that derived dataset back to the original source.

The ease of use and the different amount of widgets they offer.

Knowi is an incredibly flexible web-based tool. You can join data from multiple sources (a previously developed Knowi dataset being one of them), add transformations _a piacere_, and then have the resulting dataset available as a "live" connection to data (with or without cache), refreshing at specified intervals, or "triggered". The many visualization options are quite customizable, and very importantly there's the option of developing your own via HTML/JS. I haven't dived into embedding, but I saw there are lots of options there, too, and regardless of embedding dashboards can have a public shareable link. You can also set up alerts or scheduled PDF reports via email/Slack/Teams/webhooks. And on top of everything, the tool is constantly evolving, adding features and fixes every week. Knowi has everything!
