DuckDuckGo

• 1. Introduction

  ›

  DuckDuckGo, a search engine built around online privacy, traces back to a stained glass class in 2007. That is where Gabriel Weinberg got the idea of improving how people search. Today the company behind it is headquartered in Paoli, Pennsylvania. It is privately held and has about 335 employees. Those are small numbers next to the giants of search. How does a company that size find its results and pay its bills? How did it persuade people to switch? And what happens when the companies it depends on change the rules?

• 2. A Name That Popped Up

  ›

  Names Database, a social network that no longer exists, was one of Gabriel Weinberg's earlier ventures. He also tried a couple of search startups, and they flopped. Then, in 2008, he launched DuckDuckGo. The name refers to the children's game duck, duck, goose, though Weinberg played down any deeper meaning. He said: "Really it just popped in my head one day and I just liked it. It is certainly influenced/derived from duck, duck, goose, but other than that there is no relation, e.g., a metaphor."

  TechCrunch featured the young site on its Elevator Pitch Friday in 2008. That same year it was a finalist in the BOSS Mashable Challenge.

  Until October 2011, Weinberg paid for everything himself. After that, a Series A round led by Union Square Ventures brought in outside money. The scale stayed modest. In 2011 the company earned 115,000 dollars in revenue and had three employees, plus a small number of contractors.

  In a lengthy profile in November 2012, The Washington Post offered a striking verdict. It wrote: "Weinberg's non-ambitious goals make him a particularly odd and dangerous competitor online." The paper reasoned that he could do almost everything Google or Bing could not, because doing so would damage their business models. It called the situation "asymmetrical digital warfare." His backers at Union Square Ventures were quoted saying that Google was vulnerable.

• 3. Borrowed Results

  ›

  Over 400 sources, by the company's own count, feed the results on a DuckDuckGo page. They include Bing, Yahoo Search BOSS, Wolfram Alpha, Yandex and its own web crawler, called DuckDuckBot. Crowdsourced reference sites fill the knowledge boxes beside the results. TechCrunch described the service as a "hybrid" search engine, since it is built primarily on search APIs from various vendors. The machinery underneath runs on nginx, FreeBSD and Linux. Browsers without JavaScript can use HTML and lite versions of the search.

  A Bing API outage in 2024 made DuckDuckGo stop showing results altogether. The outage revealed how large a share of its results Bing supplied. Prices moved too. Bing dramatically raised rates for its search API in 2022, after ChatGPT debuted. By August 2025, Bing planned to cut off access to its search APIs to sell more AI-related ones. DuckDuckGo believed that larger companies with long-term deals, like itself, would not be affected.

  Ads from the Yahoo-Bing search alliance network supply the company's main revenue. They are matched to the keywords and terms in each search query.

  The site eHow publishes 4,000 articles per day from paid freelance writers. DuckDuckGo deletes results for it and for similar companies it considers article mills. Weinberg called that output low quality and designed specifically to rank highly in Google's search index. Pages with heavy advertising are filtered as well. Assessments from other organizations help down rank websites judged to have low journalistic standards.

  Instant answers, which sit at the top of the page, are called zeroclickinfo. The idea is that users find what they need on the results page without clicking anything. The answers come from third-party APIs or static data sources such as text files. A community of open source contributors created and maintained them. That community became known as DuckDuckHack, launched in 2012 so users could code and crowdsource their own plugins. On the 31st of August 2017, DuckDuckHack went into maintenance mode, and only bug-fix pull requests are approved.

  As of May 2026-13,566 bang keywords let users jump straight into the search tool of a particular website. In December 2018, around 2,000 bangs were deleted. Some were broken. Others, such as searches on sites for pirated material, were removed for liability reasons.

• 4. Privacy as a Pitch

  ›

  In 2010, DuckDuckGo began using privacy to set itself apart from its competitors. Its policy is that it does not store IP addresses or user information used for micro-targeting or sold to advertisers on other search engines. In July 2010, Weinberg opened a community website at duck.co. The public could report problems there and request features. They could also discuss ways to spread the use of the engine and whether to open source the code.

  August 2010 brought anonymous searching over the Tor network, including an exit enclave and a Tor hidden service, also called an onion service. Tor routes traffic through a series of encrypted relays. Weinberg said: "I believe this fits right in line with our privacy policy. Using Tor and DDG, you can now be end-to-end anonymous with your searches. And if you use our encrypted homepage, you can be end-to-end encrypted as well." A newer v3 onion service followed in July 2021.

  By 2011, Linux Mint and the Midori web browser had switched to DuckDuckGo as their default search engine.

  The Edward Snowden leaks in 2013 brought far more awareness of surveillance, and DuckDuckGo gained users. On Monday the 17th of June 2013, the company said on Twitter that it had three million daily direct searches. The average for May 2013 had been 1.8 million daily direct searches. Some people linked the jump to the exposure of PRISM and other programs run by the National Security Agency.

  Danny Sullivan wrote on Search Engine Land that the growth was nowhere near enough to show any real switching by the searching public. He concluded that no one cares about private search. Caleb Garling of the San Francisco Chronicle disagreed. He wrote: "I think this thesis suffers from a few key failures in logic." Traffic had risen, Garling argued, and few people yet knew DuckDuckGo existed.

  By September 2013, the search engine hit 4 million searches per day. Privacy worries boosted its users again in 2018, after the Cambridge Analytica scandal. On the 11th of January 2021, it logged 102.2 million daily searches. Even so, as of 2022 it held about 3% of the search market in the United States.

• 5. Winning Defaults

  ›

  On the 26th of September 2013, GNOME made DuckDuckGo its default search engine, starting with Web 3.10. A search engine that nobody has to type in by hand is worth far more than one that people must seek out.

  At its WWDC keynote in 2014, Apple announced that DuckDuckGo would be a search option in Safari, on both iOS 8 and OS X Yosemite. The Pale Moon web browser, starting with version 24.4.0, made it the default and listed it on the browser's homepage. On the 10th of November 2014, Mozilla added it as a search option in Firefox 33.1. On the 30th of May 2016, the Tor Project made it the default search engine for Tor Browser 6.0.

  In July 2016, DuckDuckGo announced an extension of its partnership with Yahoo. All users gained date filtering of results and additional site links. It also had partnerships with Bing, Yandex and a crowdsourced reference site, to produce results or use their features. The company confirmed that it does not share user information with partner companies, as has always been its policy.

  Talks with Apple in 2018 and 2019, about becoming the default in Safari's private browsing mode, were ultimately unsuccessful. DuckDuckGo did integrate other privacy features into Safari. On the 15th of January 2019, it announced that all map and address-related searches would be powered by Apple Maps, on desktop and mobile. In March 2019, Google added DuckDuckGo to the default search engine list in Chrome.

  In September 2022, Debian package maintainers switched the default search engine in Chromium to DuckDuckGo for privacy reasons.

  The company registered the domain ddg.gg on the 22nd of February 2011. It works as a short alias that redirects to duckduckgo.com. In December 2018, Google transferred ownership of duck.com to DuckDuckGo. It is not known what price, if any, DuckDuckGo paid. That address now also serves as the home of its email protection service.

• 6. Beyond the Search Box

  ›

  Chrome and Firefox are among the browsers that can run DuckDuckGo's extensions. The company also launched its own web browser, the DuckDuckGo Private Browser, which became available on desktop in 2022. Both offer some protection against web tracking and other privacy intrusions across all browsing, not only DuckDuckGo searches.

  In May 2022, a Bleeping Computer report by security researcher Zach Edwards found that the Private Browser let Microsoft's trackers keep running on non-DuckDuckGo websites. Google and Facebook trackers were blocked. Weinberg replied: "unfortunately, our Microsoft search syndication agreement prevents us from doing more to Microsoft-owned properties. However, we have been continually pushing and expect to be doing more soon." He added that most browsers "don't even attempt" to block third-party scripts, so users were still safer than elsewhere. In August 2022, DuckDuckGo began blocking Microsoft's trackers, saying the policy preventing it no longer applied.

  July 2021 saw the introduction of Email Protection. Users can claim an address ending in @duck.com. The inbox receives emails, strips them of data trackers, and forwards them to the user's private email address. It launched in beta for users of the Private Browser on iOS and Android.

  Google's Accelerated Mobile Pages framework was another target. DuckDuckGo said that when someone loads or shares a Google AMP page from its apps or extensions, the original publisher's webpage is used instead.

  In April 2024, DuckDuckGo introduced Privacy Pro, a paid subscription that includes a VPN, Personal Information Removal and Identity Theft Restoration. It launched for users of the DuckDuckGo browser in the United States. Subscription fees became a second source of revenue alongside ads.

  In 2021, DuckDuckGo gave 200,000 dollars to the Center for Information Technology Policy and 150,000 dollars to the Electronic Frontier Foundation. European Digital Rights, known as EDRi, and The Markup each received 75,000 dollars.

  On GitHub, some of DuckDuckGo's source code sits under the Apache 2.0 License as free and open-source software. The core remains proprietary.

  Starting in 2025, DuckDuckGo rolled out Easter eggs in the form of logo variants. Dax, the company's mascot, appears dressed as characters from popular culture when users search for them. As of April 2026, over 750 of these logos had been discovered. Weinberg said that designing them "involves AI, but it is still a fairly manual process, and DuckDuckGo's design team (and others) have been involved in it."

  In 2026, the company launched Collaborations, partnerships with Atoms, Yubico and Cotton Bureau. Together they make limited-edition merchandise with a dark mode theme.

• 7. The AI Question

  ›

  March 2023 was when DuckDuckGo added Search Assist, formerly called DuckAssist, to its instant answers. It uses large language models from OpenAI and Anthropic to generate answers to users' questions. The answers draw on reputable online reference works, including Britannica. A separate web crawler, called DuckAssistBot, does that sourcing, apart from the main DuckDuckBot.

  Four settings control how often Search Assist appears: Never, On-demand, Sometimes and Often. On-demand means it appears only when Assist is clicked. Sometimes means when it is highly relevant. Often means on a wide range of searches. Results also carry a More button that asks the AI for a longer answer. Another button lets users ask a follow-up question in Duck.ai, the company's chatbot.

  June 2024 saw the introduction of Duck.ai, known as DuckDuckGo AI Chat during beta. It is an opt-in chatbot for anonymous, private conversations with multiple large language models. It exited beta in March 2025. Free access covers OpenAI's GPT-4o mini, GPT-5 mini and GPT-OSS 120B. It also covers Anthropic's Claude 3.5 Haiku, Meta's Llama 4 Scout and Mistral AI's Mistral Small 3. Subscribers get higher usage limits and advanced models, including GPT-4o, GPT-5.1, Claude Sonnet 4.5 and Llama 4 Maverick, as of December 2025.

  According to DuckDuckGo, Duck.ai conversations are stored locally on the user's device. Prompts and outputs are not retained for model training, because all data sent to providers is anonymized. No metadata about the user or their device is shared with the AI companies. Users can disable Duck.ai and Search Assist. Computeractive said Duck.ai was their preferred privacy-focused AI.

  In January 2026, Duck.ai Image Gen exited beta. It lets users create images by entering descriptive prompts. The images are stored locally on users' devices, with C2PA-compliant metadata for verification. Around the same time, the option to add reference images arrived. Voice chat was also added to Duck.ai that month.

  From the 16th to the 26th of January 2026, DuckDuckGo ran a poll asking whether users approved of the AI features on the site. Criticism of AI had prompted it. Ninety percent of people voted "No AI," and 10% voted "Yes AI." No changes were made to DuckDuckGo as a result. The company did create two new DuckDuckGo websites, one with AI and one without.

• 8. Fans, Foes and Rivals

  ›

  In a June 2011 article, Harry McCracken of Time compared DuckDuckGo to his favorite hamburger restaurant, In-N-Out Burger. He wrote: "It feels a lot like early Google, with a stripped-down home page." Just as the burger chain skips lattes and sundaes, he said, DuckDuckGo skipped news, blogs, books and images. He did not claim it beat Google on relevance. He did say it was really good at bringing back useful sites. Time put it on its list of "50 Best Websites of 2011."

  On the 21st of May 2014, DuckDuckGo released a redesign focused on smarter answers and a more refined look. It added images, local search, auto-suggest, weather, recipes and more. That ended the bare-bones approach McCracken had praised.

  Thom Holwerda reviewed the search engine for OSNews and praised its privacy features and its shortcuts to site-specific searches. He criticized Google for "tracking pretty much everything you do." He worried especially because such information could be subject to a United States government subpoena.

  In 2012, Google faced accusations that it was a monopoly, and it responded by naming DuckDuckGo as a competitor. Weinberg was reportedly "pleased and entertained" by that acknowledgment.

  In November 2019, Twitter CEO Jack Dorsey said he loved DuckDuckGo and that it had been his default search engine for a while. He added that the app was even better. Conservative political commentators Ben Shapiro and Dan Bongino have also endorsed it. Internal surveys by DuckDuckGo found its users held a wide variety of political leanings.

  On the 1st of March 2022, in response to the Russian invasion of Ukraine, DuckDuckGo paused its partnership with Yandex Search. Weinberg said in a tweet that DuckDuckGo would down-rank sites associated with Russian disinformation. Some users criticized that as censorship and a violation of its commitment to "unbiased search." The company answered: "The primary utility of a search engine is to provide access to accurate information. Disinformation sites that deliberately put out false information to intentionally mislead people directly cut against that utility."

  TorrentFreak reported in April 2022 that DuckDuckGo had blocked results for some major piracy sites, including The Pirate Bay, 1337x and FMovies. It also reported the block of the video downloading software Youtube-dl. In a statement to Engadget, DuckDuckGo said The Pirate Bay and Youtube-dl were never removed when users searched by name or web address. It said there were problems with "site:" queries and other searches, and that those had been fixed.

  In December 2024, DuckDuckGo criticized the remedies Google proposed in an antitrust case about search monopolies. The company said the proposal maintains the existing balance of power rather than fostering genuine competition. Weinberg, its CEO, said the measures "attempt to maintain the status quo" and are insufficient to give smaller players fair access to markets.

  As of 2026, approximately 53% of DuckDuckGo's monthly global traffic comes from the United States. Germany is the largest source outside it, at 8%. The United Kingdom accounts for 5%, while Canada and France each account for 3%.
