A complete search platform 

Add search functionality to cloud, iOS, Android, or web apps in minutes with ease.

Fully hosted search service

Sajari is a cloud-native application that is fully hosted so there's nothing for you to manage or maintain. It just works.

Instant indexing

Our instant indexing technology means there's no more waiting for periodic updates. Edits and new pages are added immediately.

Add features intuitively

Add instant search, auto-complete, spell checking, and more with a few keystrokes in the pipeline editor. With Sajari, features that would have taken days or even weeks to build can be added in minutes.


The Sajari REST API and React and Javascript libraries enable you to customize app search through the use of composable components.

Scales to meet demand

Sajari has been battle-tested at more than 1000 queries/second, so it's ready to meet your users' demands anytime. 

“Sajari is a search solution that goes above and beyond what I was expecting - having multiple collections under one account is a game-changer. The support is useful, responsive, and extremely efficient.”
