Looking for suggestions for online simulators. Would be willing to pay for a subscription, however I can NOT download software to my computer. Looking to "build" circuits with LED and 555 timers, etc. and 'test' them on the simulator before building them. Any suggestions would be appreciated.

I use LTspice, which is a good, free Spice simulator, but it must be downloaded.
Are you using a computer at work where downloaded software is not allowed?

For most accurate results, you want one that uses a Spice engine and Spice parts models for simulation
There are a number of those listed as working online, but I'm not familiar with them.
You might try several to see which seems the best for your purposes.

Why do you think you need a simulator for such simple circuits? Just about everything you need to know about a 555 timer is in the datasheet.

The Falstad simulator is ok, for simple simulations, but if it does not use Spice models, it will likely not be particularly accurate in simulating circuits with complex active components such as ICs (op amps, etc.).

I use it still because it provides a real time output which aids in imaging circuit operation. I'm yet to find a similar function in LTspice that just spits out a graph with some plot.

Yes...it doesn't output "pretty" pictures (that's not its purpose), but you can be confident it will be accurate.
I can't say the same for Falstad.

Can't argue with that however TS asked for an online simulator. Does a better one exist that is free and web based?

Maybe "EasyEDA", it uses the LTspice engine but overlays a graphical user interface.
I didn't like it because it "did things in the background" that broke some of my models that I had been using for years without problems.
