Guides for AI builders

The 75-tool directory tells you what each tool does. These guides explain the decisions around them – when to reach for an AI search API vs. a SERP scraper, what changes when your agent needs JavaScript rendering, how pricing per request scales into a real monthly bill, and where the open-source path saves money vs. where it eats engineering time.

Every guide is updated when the underlying market shifts – pricing changes, new launches, regulatory rulings – and dated accordingly. If you want a deeper editorial take on a specific tool, the blog covers funding, legal status, and category landscape pieces.
