The alternatives

unlob

$0.40/1k

Our own index, admitted rather than ranked. Metadata-only passage hits, six coverage-graph traversal tools, an MCP server, and an endpoint that tells you why any URL is or is not in the index. Smaller than the well-funded incumbents, and considerably cheaper than all of them.

Perplexity Sonar

$14/1k

Search and synthesis in one call. You get an answer rather than results, which is convenient until you need to control retrieval yourself.

Own index· Free: API credits included with Perplexity Pro

Grounding with Bing Search

Microsoft's designated successor to the retired Bing Search API, available only inside Azure AI Foundry. A platform commitment, not an API swap.

Own index· Free: Azure free credits only

Bing Web Search API

For a decade the default independent web search API. Retired on 11 August 2025, taking Web, Image, News, Video, Entity and Custom Search with it.

Own index· Free: None — retired

Retired 11 August 2025

OpenAI web search tool

The built-in search tool in the Responses API. Zero integration work if you are already on OpenAI, and no control over retrieval whatsoever.

Partial index· Free: None separate from API credit

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: Free trial credit

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

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

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 monthly credits — the perpetual free tier was retired in February 2026

Free developer tier removed February 2026

Frequently asked questions

What is the best alternative to Grounding with Google Search?

It depends what you are replacing. If you need an independent index at the lowest price, unlob is $0.40 per 1,000 queries against Grounding with Google Search's $14. If you need the largest possible index, Grounding with Google Search may still be the right tool — we say so on our comparison page rather than pretending otherwise.

Does Grounding with Google Search own its own web index?

Yes — Google's index. That matters because a provider without its own index inherits the deprecation and repricing risk of whoever it depends on.

How much does Grounding with Google Search cost?

$14 per 1,000 search queries on Gemini 3.x after 5,000 free prompts per month. Gemini 2.5 models use the older scheme at $35 per 1,000. One prompt can trigger several billed queries.
