100 Websites You Only Need on the Internet

#

The internet has billions of pages. Most of them are noise. This Data Science Resources (DSR) post collects 100 websites that stay useful across common work: building with AI, creating media, learning to code, designing, marketing, staying productive, growing a career, and managing money.

How to use this list: bookmark it, pick one category that matches your biggest problem today, and try one or two links in that section. Most entries offer a free tier or a free plan. Pair tools deliberately—for example, a chat assistant, a design app, and a video tool can cover a simple content workflow.
