I found this thing years ago and still occasionally go to it to play around with different circuit concepts. Very cool!

I designed an actual board with this. Would have been SOL without it.

Same here. It never hit production, but this simulator was fully-featured enough to replace SPICE and accompany breadboard prototypes before I ordered a PCB run.

I used and enjoyed circuitlab.io until it went for-pay only. Nice to have an easy to use free alternative for very casual hobbyists like me.

That would be https://www.circuitlab.com/ -- I built it :) Edit: if anyone wants, reply with your CircuitLab username and I'll give you a free membership upgrade when I get home this evening.

Thanks, great site! My username is TKems

If that's also true for brand-new users, the username is the same!

Thank you, I'm just at the stage where I'm learning schematics and this looks like a fantastic tool!

I'll throw my hat into the ring as well. I have also recently been building a small signal AC analysis circuit simulator [1]. The main idea behind it is to convert a closed source tool that has been around for years within the LIGO scientific collaboration to one that is open source and implemented in Python. It's almost functionally complete, can simulate transfer functions and (accurate) noise from op-amps, resistors, capacitors and inductors in circuits with current or voltage sources. There is a library of popular op-amps for which we've measured the noise, open loop gain and various other parameters, available to be simulated with.
