What is Algolia?
Algolia is a search and discovery API that sits between your application and your data, returning search results in milliseconds. It's designed for websites and applications that need fast, relevant search experiences without building search infrastructure from scratch. The service handles the complex work of indexing content, ranking results by relevance, and learning from user behaviour. You integrate it via API, then tune how results rank through a dashboard. It works well for e-commerce sites, marketplaces, documentation, and any application where users need to find content quickly.
