A free alternative to Algolia
Algolia is a hosted site-search API billed by usage. FreeSerp is a free, keyless search API for AI agents on our own 3.1B+ page web index — a drop-in alternative you can call with no key, no signup and no per-request bill.
curl 'https://freeserp.ai/api.php?index=web&q=best+crm+for+small+business&size=5'Algolia is infrastructure you fill with your own documents and operate yourself. FreeSerp is the opposite shape: a hosted, already-populated index — FreeSerp Global (3.1B+ web pages) plus FreeSerp Main (20M+ site profiles) — exposed as one keyless JSON endpoint — nothing to deploy, feed or scale.
Point your agent at FreeSerp’s JSON endpoint with index=web and it searches 3.1B+ pages — url, title, snippet, language, publication date and a site card (Domain Rating, category, live date) per result. The default index gives you 20M+ site profiles with LLM summaries, filterable and sortable on every field. Same shape you would wire Algolia into, minus the account and the invoice.
