Algolia

Algolia provides search-as-a-service with typo tolerance, faceted filtering, and sub-millisecond response times. But its per-search-request pricing ($1 per 1,000 requests on the Build plan) creates costs that scale with traffic — a popular site can rack up significant search bills.

Meilisearch and Typesense are the two leading open source search engines purpose-built for application search (as opposed to Elasticsearch, which is designed for log analysis and data analytics). Meilisearch offers typo tolerance, faceted search, and a dead-simple API — it's designed to be the easiest search engine to set up and use. Typesense provides similar features with a focus on performance and includes built-in API key management, curation, and analytics.

Both alternatives can be self-hosted for fixed infrastructure costs, eliminating per-request pricing. A site handling 10 million search requests per month would pay Algolia $10,000/month. Self-hosted Meilisearch or Typesense on a $50-100/month server handles the same volume easily.

The feature gap has narrowed significantly. Both Meilisearch and Typesense support typo tolerance, faceted filtering, geo-search, multi-index search, and AI-powered vector search. Algolia still leads in pre-built UI components (InstantSearch), analytics depth, and A/B testing for search results. For most applications, the open source alternatives provide sufficient search quality at a fraction of the cost.
