You could try Glassdoor, but my understanding is that it’s not as accurate as levels.

A surprising number of people don’t know about levels.fyi

Go to levels.fyi, find some companies and compare at your level. For a long time I was like “ain’t no way these numbers are accurate, people are getting paid that much?” YES THE NUMBERS ARE ACCURATE; your company’s excuses for a shitty raise this year (“blah blah market conditions, blah blah you are already on the upper end of your band, let’s work on a promotion next year”) are bullshit.
