My first instinct based on a cursory glance (ie. specific language compatibilities) is that it's a portable embedded database for data analytics of the cybersecurity domain, particularly mobile penetration testing possibly.
Echoing the sentiment for Brave Browser as well. It's been great as a faster alternative to Chrome so far. Haven't actually used Brave Rewards, but it's nice that it at least offers some remuneration for personalized ads.
Despite years of trying to use Firefox as my default browser, as a direct alternative to Chrome, it's never been as performant and almost always somehow clunky and reminiscent of 2000's browser bloat. I did reinstall Firefox very recently and was surprised that it was even faster than Brave Browser for non-cached page loads.
However, for some benign reason I cannot resize browser windows at all using Firefox, and it seems I'm far from alone after searching for solutions online. At least there's more browser parity now in 2019/2020 onwards.
Check out Dracula At Night for VS Code. I swear by it for every IDE possible. I'm honestly surprised it's only got around ~52k installs. I don't remember where I first found it, but I'm glad I did.
