Google will give you ISFDB results if you search for an author or title plus "isfdb" but it's not nearly as high in the rankings as it should be.

An email service that uses addresses like yourname-appname@port87.com to organize all your email into a folder for every app/service.

You can also make these addresses screen senders before their email goes through, for something like yourname-friends@port87.com.

You can mark them as public and they’ll be included in a list if someone emails the bare address (yourname@port87.com), so you can share your bare address all over the internet without getting spam.

(Full disclosure: I created and operate this service.)

This site will show you how to tackle any stain.

It's very cool to check some calculation out very quickly on your phone or tablet.

Or if you want a full local Jupyterlab experience using the same WebAssembly tech: https://jupyterlite.readthedocs.io/en/stable/_static/lab/index.html (based on the JupyterLite project: https://github.com/jupyterlite/jupyterlite)

The first and foremost thing that comes to mind is the wayback machine. It lets you archive and immortalize any moment in a website's history.

Compare the size of any two landmasses.

No idea if this is obscure or not, but for creating diagrams I've found draw.io a very useful free website/tool (there's an offline version).
The ability to hide the entire model inside the png is really neat. You can upload the png in a wiki and later on just import it to alter it again.

When I watch movies or TV shows, I constantly wonder how old an actor or actress is during the filming of it:

I've been using https://squoosh.app/ a lot recently. Found it in a similar thread

EDIT: It is an image compression site where the images never leave your device. Or so the privacy policy says anyway. It took some tweaking, but i've had some images with an 80%+ size reducrion with almost no perceivable quality loss.
