Why teams look for a Linkup alternative

The usual reason is cost predictability. Linkup does not publish a flat per-1,000 search rate, which makes forecasting a large workload harder than it should be and makes a like-for-like comparison against providers that do publish one impossible without running both.

The second is the index question. Linkup operates its own retrieval layer over partner and web sources rather than a fully independent index, so the dependency is one step removed rather than absent. For a team whose lesson from the last two years was to check what sits underneath a provider, that is the thing they come to check.

Where Linkup beats us

The sub-second tier and native parallel search are genuine engineering, and for an interactive product where a user is waiting, latency at the API is the specification that matters most. They are also independently funded and European-headquartered, which for some buyers is a data-residency and jurisdiction argument rather than a preference — and that is a requirement we cannot argue our way around.

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 own the index the answers come from rather than layering over an upstream provider, so there is nobody above us who can change terms. Like a retrieval layer we return model-ready passages with citations; unlike one, we can tell you why a URL is absent, because we hold the ledger that records it.

Tavily

$8/1k

An LLM-shaped retrieval layer returning cleaned, ranked, cited chunks rather than raw SERPs. Acquired by Nebius in February 2026.

Frequently asked questions

What is the best alternative to Linkup?

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

Does Linkup own its own web index?

Partly — Own retrieval layer over partner and web sources. It operates its own retrieval layer but is not a fully independent web index.

How much does Linkup cost?

Priced per plan and per search depth rather than a single public per-1,000 rate.
