Complex deployment. No self-service free trial. Requires support for initial configuration and scaling

Limited API

Also offers tooling for recommendations, merchandising, personalization, quizzes, and more, but many lack the maturity of Algolia (e.g., there is no personalization A/B testing)


AI can improve search result relevance, ranking, and revenue. With the release of Algolia Neural Search, customers have complete control over the AI algorithms which combine both keyword and vector search results for every query.

AI-native AI Search with end-to-end AI processing with both keywords and vectors ensuring the most relevant retrieval at scale.

AI Search

Better retrieval assists ranking; additional reinforcement learning with dynamic re-ranking to optimize results and ROI.

AI-powered query categorization, recommendations, and personalization boosted by industry’s only AI powered automatic query categorization.

Constructor uses vector embeddings as a failover method for when they provide a null keyword result.

Because only some search results have AI applied, dynamic reranking is working on sub-optimized results.


Algolia is an API-first company which can connect with any headless or composable commerce solution. Constructor has a more limited API that often requires workarounds.

Matt Taylor

Editorial Product Manager @ The Times
Algolia is very fast — able to keep up with our level of traffic… The API and SDK options are really great, and the ability to handle traffic at scale (we have a high volume)

Matt Goorley

Engineering Manager @ LTK
[Algolia] was very professional from the start. We had a great Customer Success Manager and team that provided a lot of help and was a great partner.

Clint Fischerström

Head of Ecommerce @ Swedol
I think we’ve grown leaps and bounds with Algolia. There's a lot of features that we still can tap into, which is great because I feel like we've gotten a ton out of it already.

Instead of having to go into the back end and the catalog—which would have been a technical headache—we were able to figure it out in a matter of a day, test it, and ‘boom’ it’s live.
