What kind of useful web tools do you keep bookmarked?

Hey everyone,

While browsing gaming forums and developer discussions, I realized that many of us keep a collection of useful websites bookmarked for different purposes. Sometimes they’re related to gaming tools, and other times they’re just practical calculators or utilities that make everyday tasks easier.

For example, I recently helped a friend who wanted to buy a small boat for weekend fishing trips, and we were trying to estimate what the monthly loan payments might look like. Instead of doing the math manually, we found an online boat loan calculator that quickly shows estimated payments based on loan amount, interest rate, and repayment period.

It made me think about how many helpful tools exist online that people randomly discover while browsing communities like this one.
