DuckDuckGo was founded by Gabriel Weinberg and launched on February 29, 2008, inValley Forge, Pennsylvania.[6][14] Weinberg is an entrepreneur who previously launchedNames Database, a now-defunct social network. Self-funded by Weinberg until October 2011, DuckDuckGo was then "backed byUnion Square Ventures and a handful ofangel investors."[14][15][16] Union Square partner Brad Burnham stated, "We invested in DuckDuckGo because we became convinced that it was not only possible to change the basis of competition in search, it was time to do it."[14][16] In addition,Trisquel,Linux Mint, and theMidoriweb browser switched to use DuckDuckGo as their default search engine.[17] DuckDuckGo gains revenue via advertisements and affiliate programs.[18] Thesearch engine is written inPerl[19] and runs onnginx,FreeBSD, andLinux.[7][6][20] DuckDuckGo is built primarily upon searchAPIs from various vendors. Because of this,TechCrunch characterized the service as a "hybrid" search engine.[21][22] Weinberg explained the beginnings of the name with respect to the children's game duck, duck, goose. He said of the origin of the name: "Really it just popped in my head one day and I just liked it. It is certainly influenced/derived fromduck, duck, goose, but other than that there is no relation, e.g., a metaphor."[23] DuckDuckGo was featured on TechCrunch'sElevator Pitch Friday in 2008,[21] and it was a finalist in the 2008BOSSMashable Challenge.[24]
In 2010, DuckDuckGo began using privacy to differentiate itself from its competitors.[25]
In July 2010, Weinberg started a DuckDuckGo community website (duck.co) to allow the public to report problems, discuss means of spreading the use of the search engine, request features, and discussopen sourcing the code.[26] The company registered thedomain nameddg.gg on February 22, 2011,[27] and acquiredduck.com in December 2018,[28][29][30] which are used as shortened URL aliases that redirect toduckduckgo.com, and is also used as the domain for their email protection service.[31][32][33]
We didn't invest in it because we thought it would beat Google. We invested in it because there is a need for a private search engine. We did it for the Internet anarchists, people that hang out onReddit andHacker News.
By May 2012, the search engine was attracting 1.5 million searches a day. Weinberg reported that it had earnedUS$115,000 in revenue in 2011 and had three employees, plus a small number of contractors.[35]Compete.com estimated 266,465 unique visitors to the site in February 2012.[36] On April 12, 2011,Alexa reported a 3-month growth rate of 51%.[37] DuckDuckGo's owntraffic statistics show that in August 2012 there were 1,393,644 visits per day, up from an average of 39,406 visits per day in April 2010 (the earliest data available).[38] In a lengthy profile in November 2012,The Washington Post indicated that searches on DuckDuckGo numbered up to 45,000,000 per month in October 2012. The article concluded:
"Weinberg's non-ambitious goals make him a particularly odd and dangerous competitor online. He can do almost everything thatGoogle orBing can't because it could damage their business models, and if users figure out that they like the DuckDuckGo way better, Weinberg could damage the big boys without even really trying. It's asymmetrical digital warfare, and his backers at Union Square Ventures say Google is vulnerable."[12]
GNOME releasedWeb 3.10 on September 26, 2013, and starting with this version, the default search engine is DuckDuckGo.[39][40]
At its keynote speech at WWDC 2014 on September 18, 2014, Apple announced that DuckDuckGo would be included as an option for search on bothiOS 8 andOS X Yosemite in itsSafari browser.[41][42][43] On March 10, thePale Moon web browser, starting with version 24.4.0, included DuckDuckGo as its default search engine, as well as listed it on the browser's homepage.[44] In May 2014, DuckDuckGo released a redesigned version to beta testers through DuckDuckHack.[45] On May 21, 2014, DuckDuckGo officially released the redesigned version that focused on smarter answers and a more refined look. The new version added many new features such as images,local search, auto-suggest, weather, recipes, and more.[46]
In July 2016, DuckDuckGo officially announced the extension of its partnership withYahoo! that brought new features to all users of the search engine, including date filtering of results and additional site links. It also partners withBing,Yandex, and Wikipedia to produce results or make use of features offered. The company also confirmed that it does not share user information with partner companies, as has always been its policy.[51]
In December 2018, it was reported that Google transferred ownership of the domain name Duck.com to DuckDuckGo. It is not known what price, if any, DuckDuckGo paid for the domain name.[30]
On January 15, 2019, DuckDuckGo announced that all map and address-related searches would be powered byApple Maps, both ondesktop andmobile devices.[52]
In March 2019, Google added DuckDuckGo to the default search engine list inChrome 73.[53]
Beginning in 2018,[54] the company has offeredbrowser extensions for popularweb browsers (Google Chrome,Safari, and others).[9] The company also launched its own web browser, called theDuckDuckGo Private Browser.[10] Both of these products have protections againstweb tracking and other privacy intrusions for all web browsing (not limited to DuckDuckGo searches).[55] Prior to August 2022, DuckDuckGo Private Browser did not block Microsoft tracking scripts.[56][57][58]
In July 2021, DuckDuckGo introduced itsemail forwarding feature Email Protection, which lets users claim an "@duck.com" email address generated by the service. That inbox will receive emails and strip them of data trackers before forwarding them to the user's private email address. The feature launched in beta for users of DuckDuckGo Private Browser on iOS and Android.[59]
As of March 2022[update], DuckDuckGo handled 102,704,358 daily searches on average.[60]
Also in April, DuckDuckGo said that they would protect users from being tracked by Google'sAccelerated Mobile Pages framework, stating: "When you load or share a Google AMP page anywhere from DuckDuckGo apps (iOS/Android/Mac) or extensions (Firefox/Chrome), the original publisher's webpage will be used in place of the Google AMP version".[61]
In September 2022,Debian package maintainers switched the default search engine inChromium to DuckDuckGo for privacy reasons.[62]
In April 2024, DuckDuckGo introduced Privacy Pro, a paid subscription that includes aVPN, Personal Information Removal, and Identity Theft Restoration.[63] The subscription launched to users of the DuckDuckGo browser in the United States.
DuckDuckGo does not track its users.[64][65] DuckDuckGo keepsfavicons anonymous.[66] User locations are never sent to DuckDuckGo servers, even when they allow a third party to collect their geolocations.[67] DuckDuckGo offers limited third-party tracking protection, third-party cookie protection, CNAME cloaking protection, limited devicefingerprint protection from third parties, link tracking removal, Google AMP replacement, and do-not-track requests.[68]
DuckDuckGo's results are a compilation of "over 400" sources according to itself, including Bing, Yahoo! Search BOSS,Wolfram Alpha, Yandex, and its ownweb crawler (the DuckDuckBot); but none from Google.[69][7][70][71][72] It also uses data fromcrowdsourced sites such asWikipedia, to populate knowledge panel boxes to the right of the search results.[71][73] During a Bing API outage in 2024, DuckDuckGo stopped showing results, indicating that Bing provided a substantial portion of DuckDuckGo's results.[74][75]
DuckDuckGo offersHTML andlite versions of its search for browsers withoutJavaScript capabilities.[76]
DuckDuckGo has refined the quality of its search engine results by deleting search results for companies they believe arecontent mills, such aseHow, which publishes 4,000 articles per day produced by paid freelance writers, which Weinberg states to be "low-quality content designed specifically to rank highly in Google's search index". DuckDuckGo also filters pages with substantial advertising.[77] DuckDuckGo down ranks websites deemed to have low journalistic standards.[78]
In addition to the indexed search results, DuckDuckGo displays relevant results, calledinstant answers, on top of the search page. These Instant Answers are collected from either third party APIs or static data sources like text files. The Instant Answers are calledzeroclickinfo because the intention behind these is to provide what users are searching for on the search result page itself so that they do not have to click any results to find what they are looking for. Instant answers are created by and maintained by a community of over 1,500 open source contributors. This community has come to be known as DuckDuckHack.[79] As of July 2019[update], there were 1,236 Instant Answers active.[80]
In the DuckDuckHack documentation, four types of Instant Answers are described:Goodies, Spices, Fatheads, andLongtails. These types of Instant Answer extensions are differentiated by how their data is retrieved. Goodies do not retrieve data from a third party API, whereas Spices do. Goodies instead use some form of the aforementioned static data sources, such as text files orJSON files. Fathead Instant Answers are key-value answers hosted on DuckDuckGo'sbackend. Fathead key-value pairs function similarly to a trigger for showing the respective Instant Answer. Longtail Instant Answers are full text queries to a DuckDuckGo database of articles. Paragraphs or snippets from any matching articles are returned, and the section that matches the user's query is highlighted.[81]
In March 2023, DuckDuckGo added DuckAssist to Instant Answers. Usinglarge language models fromOpenAI andAnthropic, DuckAssist generates answers to users' questions by scanning online encyclopedias (like Wikipedia andBritannica).[82][83]
In August 2010, DuckDuckGo introduced anonymous searching, including an exit enclave,[84] for its search engine traffic usingTor network and enabling access through a "Tor hidden service" (onion service).[85]3g2upl4pq6kufc4m.onion(Accessing link help)[86][87] (deprecated) was the DuckDuckGo v2 onion service on Tor.[88][89][90] This allows anonymity by routing traffic through a series of encrypted relays. Weinberg stated: "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 searching. And if you use our encrypted homepage, you can be end to end encrypted as well."[91]
In July 2021, DuckDuckGo introduced a new v3 onion service, with a new link:duckduckgogg42xjoc72x3sjasowoarfbgcmvfimaftt6twagswzczad.onion(Accessing link help).[92]
DuckDuckGo includes "!Bang" keywords, which give users the ability to search on specific third-party websites – using the site's own search engine if applicable. As of August 2020, 13,564 "bangs" for a diverse range of internet sites are available.[93] In December 2018, around 2,000 "bangs" were deleted. Some of them were deleted due to being broken, while others, such as searches of pirated content sites, were deleted for liability reasons.[94]
DuckDuckGo earns revenue by serving ads primarily from the Yahoo-Bing search alliance network.[95] As a privacy-focused search engine, the ads served on DuckDuckGo are based on keywords and terms of the search query.[96][97] As of April 2024, DuckDuckGo also makes money from subscription fees paid to access Privacy Pro.
In a June 2011 article, Harry McCracken ofTime commended DuckDuckGo, comparing it to his favorite hamburger restaurant,In-N-Out Burger:
It feels a lot like early Google, with a stripped-down home page. Just as In-N-Out doesn't have lattes or Asian salads or sundaes or scrambled eggs, DDG doesn't try to do news or blogs or books or images. There's no auto-completion or instant results. It just offers core Web search—mostly the "ten blue links" approach that's still really useful, no matter what its critics say ... As for the quality, I'm not saying that Weinberg has figured out a way to return more relevant results than Google's mighty search team. But DuckDuckGo ... is really good at bringing back useful sites. It all feels meaty and straightforward and filler-free ...[102]
The bare-bones approach cited in his quote has since changed; for instance, DuckDuckGo now[when?] hasauto-completion, instant results, and a news tab. McCracken included the site inTime's list of "50 Best Websites of 2011."[103]
Thom Holwerda, who reviewed the search engine forOSNews, praised its privacy features and shortcuts to site-specific searches as well as criticizing Google for "tracking pretty much everything you do", particularly because of the risk of such information being subject to aU.S. governmentsubpoena.[104] In 2012, in response to accusations that it was a monopoly,Google identified DuckDuckGo as a competitor. Weinberg was reportedly "pleased and entertained" by that acknowledgment.[12]
In November 2019, Twitter CEOJack Dorsey revealed his preference for using the DuckDuckGo search engine rather than Google, stating, "I love @DuckDuckGo. My default search engine for a while now. The app is even better!".[105] Conservative political commentatorsBen Shapiro andDan Bongino have also endorsed DuckDuckGo.[106]
On March 1, 2022, in response to theRussian invasion of Ukraine, DuckDuckGo paused its partnership withYandex Search.[107] Weinberg said in a tweet that DuckDuckGo will down-rank sites associated with Russian disinformation, a move which some users criticized as censorship and a violation of the search engine's commitment to "unbiased search." DuckDuckGo has defended itself from the criticism, saying that "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."[108][109][72]
In April 2022,TorrentFreak reported that DuckDuckGo had blocked search results for some majorpirating websites, includingThe Pirate Bay,1337x andFMovies, as well as video downloading softwareYoutube-dl.[110][111] In a statement toEngadget, DuckDuckGo said that The Pirate Bay and Youtube-dl were never removed from its search results if the user searched for those websites using their name or web address. DuckDuckGo also said that there were problems with "site:"search queries used for these websites and other searches and said that the problem had been fixed.[111]
In May 2022, a report fromBleeping Computer by security researcher Zach Edwards found that DuckDuckGo Private Browser allowed Microsoft's trackers to continue running while visiting non-DuckDuckGo websites, unlike Google and Facebook trackers, which were blocked. In response, Weinberg said that "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 also said given that most browsers "don't even attempt" to block third-party scripts from loading, users would still be safer than on other browsers.[56][57] In August 2022, DuckDuckGo began blocking Microsoft's trackers, saying that the policy preventing them from doing so no longer applied.[112][58] Today, DuckDuckGo continues to open articles through MSN, similar to how Google utilizes AMP.
In December 2024, DuckDuckGo criticized Google's proposed remedies in an antitrust case related to search engine monopolies. According to DuckDuckGo, the proposal maintains the existing balance of power rather than fostering genuine competition. Gabriel Weinberg, CEO of DuckDuckGo, stated that the proposed measures "attempt to maintain the status quo" and are insufficient to grant smaller players fair access to markets.[113]
In June 2013, DuckDuckGo indicated that it had seen a significant traffic increase; according to the company'sTwitter account, on Monday, June 17, 2013, it had three million daily direct searches. On average during May 2013, it had 1.8 million daily direct searches. Some[114] relate this claim to the exposure ofPRISM and to the fact that other programs operated by theNational Security Agency (NSA) were leaked byEdward Snowden.Danny Sullivan wrote onSearch Engine Land that despite the search engine's growth "it's not grown anywhere near the amount to reflect any substantial or even mildly notable switching by the searching public" for reasons due to privacy, and he concluded "No One Cares About "Private" Search".[115] In response,Caleb Garling of theSan Francisco Chronicle argued: "I think this thesis suffers from a few key failures in logic" because there had been an increase in traffic and because there was a lack of widespread awareness of the existence of DuckDuckGo.[116]
In September 2013, the search engine hit 4 million searches per day[117][118][119] and in June 2015, it hit 10 million searches per day.[6] In November 2017, DuckDuckGo hit 20 million searches per day.[6] In January 2019, DuckDuckGo set a record of 1 billion monthly searches;[120] and in November of the same year, it hit 50 million searches per day. As of March 2022[update], DuckDuckGo was receiving 102,704,358 queries per day on average.[60] On January 11, 2021, a record of over 102.2 million daily searches was achieved.[121] A new record of 111,703,299 daily searches was set on 17 January 2022.[60] In 2022, DuckDuckGo experienced stagnation and a slight decline in the number of searches per month.[122] At the end of the year 2022, they removed their traffic stats page.
Internal surveys by DuckDuckGo found that users of DuckDuckGo had a wide variety ofpolitical leanings.[106]
