Google Programmable Search Engine

The Google Programmable Search Engine (formerly known as Google Custom Search) is a platform provided by Google that allows web developers to include a specialized search engine for their own website. It provides highly customizable search results based on Google's core search technology, allowing users to narrow down searches to specific web pages or domains.

Originally launched by Google in 2006, the tool has become a staple for site administrators looking to leverage Google's indexing power without sending users away from their own platform. The product is developed and maintained primarily in the United States, though its infrastructure is hosted across Google's global data center network. As of 2026, it remains a core offering within the Google Cloud and developer ecosystem, managed by Alphabet Inc.
