Pricing detail. Instant search is $4 per 1,000 requests (up to 10 results); Fast and Auto are $7 per 1,000, and the Deep modes $12 to $15. Results beyond 10 add $1 per 1,000, contents $1 per 1,000 pages per content type, and AI summaries $1 per 1,000 pages — so a realistic RAG call costs more than the headline.

Why teams look for a Exa alternative

The usual reason is the bill. Exa is priced as a premium product and the headline search rate is only the start of it: results past the tenth, page contents and AI summaries are each charged on top, so the realistic cost of a retrieval-augmented call is some way above the number on the pricing page. A workload that looked affordable in a prototype often does not survive contact with production volume.

The second reason is scope. Exa sells search alongside extraction, answers and agentic research products, and a team that wanted retrieval sometimes finds itself buying a stack. If your pipeline already has its own reranker and its own summarisation step, most of that surface is paid-for capability you are deliberately not using.

Where Exa beats us

Exa runs a genuinely proprietary semantic index and has raised the capital to keep growing it, which shows up as breadth. On broad consumer subjects and on the long tail of the English-language web, it will find material a smaller index does not hold, and no amount of better filtering compensates for a document that is absent. If your evaluation shows coverage gaps rather than ranking problems, that is the finding that should decide this.

Every page in this section names this. A comparison that cannot say where the other product wins is an advertisement.

The alternatives

unlob

$0.40/1k

We crawl and index the web ourselves, like the vendor on this page, so there is no upstream provider who can deprecate or reprice us. The index is smaller than the well-funded incumbents, deliberately bounded rather than exhaustive, and the difference in the bill is not marginal. What you get on top is six coverage-graph traversal operations and an endpoint that explains any absence.

Parallel Search

$1/1k

A suite of web search, extraction and research APIs on a proprietary index, from the former Twitter CEO. The closest competitor to unlob by thesis.

Own index· Free: 5,000 requests per month

Brave Search API

$5/1k

A genuinely independent index of 40B+ pages, sold as a conventional search API with an LLM-context option. Long the default independent choice.

Own index· Free: $5 in free credits every month (about 1,000 Search requests), conditional on attributing the Brave Search API; plans restructured 12 February 2026

Free developer tier removed February 2026

Mojeek

A UK independent crawler and index, running since 2004. Small by comparison, but genuinely its own — and the oldest independent index still standing.

Own index· Free: Free trial with limited queries, on request

Perplexity

$1/1k

Raw web search over its own index through the Search API, and search with synthesis through the Agent API, which replaced Sonar Chat Completions in September 2026.

Own index· Free: None stated; API credits are prepaid

DataForSEO

$0.60/1k

Industrial SERP infrastructure built for SEO tooling rather than agents. The cheapest per query in the field, with the lowest-level API to match.

No own index· Free: $1 trial credit, no deposit required

Serper

$1/1k

The cheapest way to get raw Google results into an agent. Fast, minimal, and entirely dependent on Google continuing to be scrapeable.

No own index· Free: 2,500 free queries on signup

Bright Data

$1.50/1k

Proxy and unblocking infrastructure with a scraping suite and an agent-facing MCP server. Built for volume collection, priced accordingly.

No own index· Free: 5,000 SERP API requests per month (and 5,000 Web MCP requests), no card required

Linkup

$5/1k

A French grounding API returning structured, citation-carrying content for LLMs, with a sub-second "fast" tier and native parallel search.

Partial index· Free: $20 of credit, topped back up to $20 each month for eligible accounts (about 4,000 standard searches)

Frequently asked questions

What is the best alternative to Exa?

It depends what you are replacing. If you need an independent index at the lowest price, unlob is $0.40 per 1,000 searches against $4 for Exa's Instant search. If you need the largest possible index, Exa may still be the right tool — we say so on our comparison page rather than pretending otherwise.

Does Exa own its own web index?

Yes — Proprietary AI-native semantic index. That matters because a provider without its own index inherits the deprecation and repricing risk of whoever it depends on.

How much does Exa cost?

Instant search is $4 per 1,000 requests (up to 10 results); Fast and Auto are $7 per 1,000, and the Deep modes $12 to $15. Results beyond 10 add $1 per 1,000, contents $1 per 1,000 pages per content type, and AI summaries $1 per 1,000 pages — so a realistic RAG call costs more than the headline.
