Best private search engine in 2026

Almost nobody has an index

Building and maintaining a web index costs hundreds of millions a year, which is why there are four at global scale — Google, Microsoft, Yandex and Baidu — and a handful of small independent ones. Nearly every “private search engine” is a front end over one of the big four with the tracking removed.

That is a real service. When you search on DuckDuckGo, Microsoft receives the query but not your address or a profile, because DuckDuckGo sits in between. Compared with searching Google while signed in, the difference is substantial.

But it also means the product rests on a commercial agreement. If the supplier changes terms, the engine changes with it. That happened visibly in 2022, when a researcher found DuckDuckGo’s browser was permitting certain Microsoft trackers, which turned out to be a condition of the search agreement. DuckDuckGo changed the behaviour once it was public.

So this page weighs an independent index heavily. Brave Search, Mojeek and Kagi have one to varying degrees. It is the difference between a privacy promise and a privacy architecture.

Follow the money, because it is short

• DuckDuckGo: contextual ads on results, sold against the query rather than against you.
• Brave Search: ads, or a few dollars a month to remove them.
• Startpage: contextual ads, with a US adtech firm holding a significant stake in the group.
• Ecosia: ads, with most profit going to tree planting, under a structure that legally prevents anyone extracting it.
• Mojeek: a search API business and affiliate links, with nothing on the results page.
• Kagi: subscriptions only.

Only Kagi and Mojeek have no advertiser to please. That is the entire argument for both.

The Startpage question

In 2019 System1 — a US advertising technology company — took a significant stake in the group behind Startpage and StartMail. Several privacy communities dropped their recommendations. Startpage’s position is that search operations remain independent, that no data is shared, and that Dutch law governs the company.

No evidence has emerged of the data practices changing. The objection is structural: an advertising technology company’s business is the profiling of internet users, and it now has an interest in a company whose product is the opposite. This site’s whole thesis is that ownership shapes what a company eventually becomes, so it would be inconsistent to raise it about Kape and stay quiet here.

Startpage remains a good product with a real feature — Anonymous View, which opens results through a proxy so the destination never sees you — that nothing else offers. It is listed under “avoid” on this page in the sense of “know this first”, not “unsafe”.

Result quality, honestly

Google is still better at obscure and very recent queries, and pretending otherwise helps nobody. In practice the gap has narrowed to the point where most people notice it a few times a month, and the bang shortcuts in DuckDuckGo or a fallback in your browser handle those cases in a keystroke.

Kagi’s users consistently report the best quality here, which is what you would expect from an engine with no incentive to sell placement. Mojeek’s index is genuinely small and it will not serve as a daily driver for most people, but supporting the last independent crawlers has a value beyond your own results.

What we have not tested

We have not run systematic result-quality comparisons across a fixed query set, and we would rather say so than publish an impression as a finding. What is scored here is documentary: index independence, ownership, revenue model, logging policy and app data. A repeatable quality test across all six is the obvious next step.
