It's still missing a comprehensive component library like LTspice does, though.
KiCad can also simulate circuits through NGSpice, but it's missing a library and suffers from a lot of quirks.

There's a similar product at https://wokwi.com/ (with an open source core)
It's actually really useful, fast, educational. Highly recommended.
I also wish someone would revitalize falstad circuit sim (http://falstad.com/circuit/), which is still I think the best tool for experimentation with analog electronics. Just a little bit better interface and user friendliness and it would be amazing!
A somewhat more robust numerical backend (that can give error guarantees) would also be nice, you kind of have to tinker with time steps in some cases.

Perhaps peripheral (the original site has been hugged to death).
Both clashlang: https://clash-lang.org/
And Hardcaml: https://github.com/janestreet/hardcaml
have personally fueled my interest in hardware.
Dan Luu speaks eloquently and at length about how better options are needed for logic design. I would recommend both of the above to the enthusiastic novice.

Logism evolution works great and is quite modern.
