Ninety-four percent of developers use Git [6]. The remaining six percent are mostly in specialized industries — game studios, large finance companies — and even they are slowly migrating. Every other version control system has either died, is in hospice, or survives only in a corner niche. That’s a strange outcome for software one person wrote in about two weeks.

Millions of people use Claude every day — but there’s a crucial distinction that trips up beginners and developers alike: a Claude.ai subscription and an Anthropic API key are two entirely separate products with different pricing, access methods, and intended audiences. Understanding which one you actually need can save you money and prevent frustrating “why doesn’t this work?” moments.
What Is the Claude.ai Subscription? A Claude.ai subscription gives you access to Anthropic’s conversational AI interface through the web app, desktop client, and mobile apps [1]. Think of it as a Netflix-style service — you pay a flat monthly fee and get a polished, user-friendly chat experience.
