Side-by-Side Comparison
Objective metrics, no spin.
Any product with search functionality. E-commerce sites see 10–15% conversion lift from Algolia vs. basic search. Documentation sites dramatically improve developer experience.
Internal tools with <10K records — Postgres full-text search is free and sufficient.
Companies of 500+ employees where knowledge lives across many SaaS tools and people lose hours daily searching.
