Pricing detail. $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.

Why teams look for a Grounding with Google Search alternative

Cost, and specifically cost that is hard to predict. Grounding is billed per search query rather than per prompt, and a single prompt can trigger several of them, so the relationship between what a user does and what you are charged is indirect. Teams discover the multiplier in a monthly bill rather than in a load test.

The second reason is control. Grounding decides what to retrieve and hands the model the result; you cannot filter by content type, require an exact identifier, impose a corroboration threshold, or ask why something is absent. For an assistant that is fine. For a workload that has to defend its retrieval, the absence of those levers is disqualifying.

Where Grounding with Google Search beats us

It is Google's index behind it, which is the largest and most current corpus available through any API, and the integration is a configuration flag if you are already building on Gemini. On pure retrieval quality across the open web this is the strongest option in the field, and anyone claiming otherwise is selling something.

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 are a retrieval API rather than a platform feature, which is the whole trade. You lose the configuration-flag integration and the largest index in the world; you gain filters, corroboration thresholds, exact-term requirements, an explicit answer about absence, and a per-1,000 price you can forecast from your own traffic.

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.

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.
