DuckDuckGo

Early years

Gabriel Weinberg got the idea to improve the search experience in a 2007 stained glass class.^[12] Weinberg tried a couple of search startups that flopped before launching DuckDuckGo in 2008.^[12]

Weinberg is an entrepreneur who previously launched Names Database, a now-defunct social network. Self-funded by Weinberg until October 2011, DuckDuckGo's Series A was led by Union Square Ventures.^[12] The search engine runs on nginx, FreeBSD, and Linux.^[7][6][13] DuckDuckGo is built primarily upon search APIs from various vendors. As a result, TechCrunch characterized the service as a "hybrid" search engine.^[14][15] 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 from duck, duck, goose, but other than that there is no relation, e.g., a metaphor."^[16] DuckDuckGo was featured on TechCrunch's Elevator Pitch Friday in 2008,^[14] and it was a finalist in the 2008 BOSS Mashable Challenge.^[17]

In 2010, DuckDuckGo began using privacy to differentiate itself from its competitors.^[18][12] Linux Mint^[19] and the Midori web browser^[20][21] had switched to DuckDuckGo as their default search engine by 2011.

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 discuss open sourcing the code.^[22] The company registered the domain name ddg.gg on February 22, 2011,^[23] and acquired duck.com in December 2018,^[24][25][26] which are used as shortened URL aliases that redirect to duckduckgo.com, and is also used as the domain for their email protection service.^[27][28][29]

Growth in the 2010s

Weinberg reported that it had earned US$115,000 in revenue in 2011 and had three employees, plus a small number of contractors.^[31] In a lengthy profile in November 2012, The Washington Post concluded:

Weinberg's non-ambitious goals make him a particularly odd and dangerous competitor online. He can do almost everything that Google or Bing 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.^[10]

The Edward Snowden leaks in 2013 resulted in a lot more awareness about surveillance and growth in users of DuckDuckGo.^[32] Growth in privacy concerns also boosted users in 2018 after the Cambridge Analytica scandal.^[12]

GNOME made DuckDuckGo its default search engine on September 26, 2013, starting with Web 3.10.^{[33][34][non-primary source needed]}

At its keynote speech at WWDC 2014 on September 18, 2014, Apple announced that DuckDuckGo would be included as a search option in both iOS 8 and OS X Yosemite in its Safari browser.^[35][36][37] On March 10, the Pale 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.^{[38][non-primary source needed]} 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.^{[39][non-primary source needed]}

On November 10, 2014, Mozilla added DuckDuckGo as a search option to Firefox 33.1.^[40][41] On May 30, 2016, The Tor Project, Inc made DuckDuckGo the default search engine for Tor Browser 6.0.^[42][43][44]

In July 2016, DuckDuckGo officially announced the extension of its partnership with Yahoo! that brought new features to all users of the search engine, including date filtering of results and additional site links. It also had partnerships with Bing, Yandex, and Wikipedia to produce results or to use their features. The company also confirmed that it does not share user information with partner companies, as has always been its policy.^[45]

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.^[26]

In 2018 and 2019, DuckDuckGo held ultimately unsuccessful talks with Apple about the possibility of becoming the default search option on Safari's private browsing mode though had successfully integrated other privacy features into Safari.^[46] On January 15, 2019, DuckDuckGo announced that all map and address-related searches would be powered by Apple Maps, both on desktop and mobile devices.^[47]

In March 2019, Google added DuckDuckGo to the default search engine list in Chrome.^[48]

The company has offered browser extensions for popular web browsers (including Google Chrome and Firefox).^[49] The company also launched its own web browser, called the DuckDuckGo Private Browser, which became available on Desktop in 2022.^[50] Both of these products offer some protections against web tracking and other privacy intrusions for all web browsing (not limited to DuckDuckGo searches).^[51] Before August 2022, DuckDuckGo Private Browser did not block Microsoft tracking scripts.^[52][53][54]

2020s

In July 2021, DuckDuckGo introduced its email forwarding feature, Email Protection, which lets users claim an "@duck.com" email address generated by the service. That inbox will receive emails, strip them of data trackers, and forward them to the user's private email address. The feature launched in beta for users of DuckDuckGo Private Browser on iOS and Android.^[55]

Also in April, DuckDuckGo said that they would protect users from being tracked by Google's Accelerated Mobile Pages framework, stating: "When you load or share a Google AMP page anywhere from DuckDuckGo apps (iOS/Android/MacOS) or extensions (Firefox/Chrome), the original publisher's webpage will be used in place of the Google AMP version".^[56]

In September 2022, Debian package maintainers switched the default search engine in Chromium to DuckDuckGo for privacy reasons.^[57]

In April 2024, DuckDuckGo introduced Privacy Pro. This paid subscription includes a VPN, Personal Information Removal, and Identity Theft Restoration.^[58] The subscription launched to users of the DuckDuckGo browser in the United States.

Starting in 2025, DuckDuckGo rolled out a series of Easter eggs featuring variants of the DuckDuckGo logo with Dax (DuckDuckGo's mascot) dressed as characters from popular culture when users search for the respective characters. There are currently over 750 discovered pop culture logos as of April 2026.^{[59][better source needed]} Weinberg claimed that designing these images "involve[s] AI, but it is still a fairly manual process, and [DuckDuckGo's] design team (and others) have been involved in it."^{[60][better source needed]}

By August 2025, Bing planned to cut off access to its search APIs in a push to sell more AI-related APIs, though DuckDuckGo believed that larger companies like it with long-term deals would not be affected.^[61] Bing had dramatically raised rates for its search API in 2022 after ChatGPT debuted.^[61]

In 2026, DuckDuckGo introduced "Collaborations", partnerships with companies such as Atoms, Yubico, and Cotton Bureau to create limited-edition "dark mode"-themed merchandise.^[62]

Privacy

DuckDuckGo does not store IP addresses or user information that are used for micro-targeting or sold to advertisers on other search engines.^[63]

Search results

DuckDuckGo's results have used a compilation of "over 400" sources according to itself, including Bing, Yahoo! Search BOSS, Wolfram Alpha, Yandex, and its own web crawler (the DuckDuckBot).^[64][65][66] It also uses data from crowdsourced sites such as Wikipedia, to populate knowledge panel boxes to the right of the search results.^[65][67] During a Bing API outage in 2024, DuckDuckGo stopped showing results, indicating that Bing provided a substantial portion of DuckDuckGo's results.^[68][69]

DuckDuckGo offers HTML and lite versions of its search for browsers without JavaScript capabilities.^[70][71][72]

DuckDuckGo has refined the quality of its search engine results by deleting search results for companies they believe are content mills, such as eHow, 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.^[73] DuckDuckGo uses assessments by other organizations to down rank websites deemed to have low journalistic standards.^[74]

Instant Answers

In addition to the indexed search results, DuckDuckGo displays relevant results, called instant answers, at the top of the search page. These Instant Answers are collected from third-party APIs or static data sources such as text files. The Instant Answers are called zeroclickinfo 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 open source contributors.^[75] This community came to be known as DuckDuckHack,^[76] which was launched in 2012 as a way for users to code and crowdsource their own plugins.^[77] As of August 31, 2017, DuckDuckHack was placed in maintenance mode; as such, only pull requests for bug fixes will be approved.^[76]

In March 2023, DuckDuckGo added Search Assist (formerly known as DuckAssist)^[78] to Instant Answers. Using large language models from OpenAI and Anthropic, Search Assist generates answers to users' questions by sourcing reputable online encyclopedias (like Wikipedia or Encyclopedia Britannica)^[79][80][81] using its own web crawler, the DuckAssistBot,^[82] separate from DuckDuckGo's main web crawler, the DuckDuckBot. Users can choose how often they want it to appear: Never, On-demand (only when Assist is clicked), Sometimes (when highly relevant), or Often (on a wide range of searches).^[83] Search Assist results also contain a "More" button, which allows users to have the AI generate a longer answer,^[84] and a button which allows users to ask a follow-up question using DuckDuckGo's AI chatbot, Duck.ai.^{[citation needed]}

Tor access

In August 2010, DuckDuckGo introduced anonymous searching, including an exit enclave,^[85] for its search engine traffic using Tor network and enabling access through a "Tor hidden service" (onion service).^{[86][non-primary source needed]} 3g2upl4pq6kufc4m.onion ^{(Accessing link help)[87][88]} (deprecated) was the DuckDuckGo v2 onion service on Tor.^[89][90][91] 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 searches. And if you use our encrypted homepage, you can be end-to-end encrypted as well."^{[92][better source needed]}

In July 2021, DuckDuckGo introduced a new v3 onion service, with a new link: duckduckgogg42xjoc72x3sjasowoarfbgcmvfimaftt6twagswzczad.onion ^{(Accessing link help)}.^[93]

Bangs

DuckDuckGo includes "!Bang" keywords, which let users search specific third-party websites using the site's own search engine, if applicable. As of May 2026, 13,566 "bangs" for a diverse range of internet sites are available.^[94] In December 2018, around 2,000 "bangs" were deleted. Some of them were deleted because they were broken, while others, such as searches for pirated content sites, were deleted for liability reasons.^[95]

Duck.ai

Duck.ai (known as DuckDuckGo AI Chat during beta) is an opt-in chatbot that enables users to interact anonymously and privately with multiple large language models (LLMs).^[96] The service functions as an extension to Search Assist, and is also slightly similar to Google's own AI service, Gemini. Introduced as a freemium service in June 2024 and exiting beta in March 2025,^[97][98] Duck.ai provides free access to models including OpenAI's GPT-4o mini, GPT-5 mini and GPT-OSS 120B, Anthropic's Claude 3.5 Haiku, Meta's Llama 4 Scout, and Mistral AI's Mistral Small 3, while users with the DuckDuckGo subscription can receive higher usage limits and access advanced models including GPT-4o, GPT-5.1, Claude Sonnet 4.5, and Llama 4 Maverick as of December 2025. DuckDuckGo states that conversations within Duck.ai are stored locally on the user's device, and that prompts and outputs are not retained for model training because all data sent to providers is anonymized.^[99][100] No metadata about the user or their device is shared with AI companies.^[100] Users can disable Duck.ai and/or Search Assist. Computeractive said Duck.ai was their preferred privacy-focused AI.^[101]

Duck.ai Image Gen is a feature that allows users to create AI-generated images by entering descriptive prompts. Generated images are stored locally on users' devices, with C2PA-compliant metadata for verification.^[102] The feature exited beta in January 2026. The optional ability to add reference images was also added around that time.

Voice chat was also added to Duck.ai in January 2026.^[103][100]

Donations

The company supports charitable organizations that work to improve privacy;^[112] including in 2021 $200,000 to the Center for Information Technology Policy, $150,000 to the Electronic Frontier Foundation, $75,000 to European Digital Rights (EDRi) and $75,000 to The Markup.^[113]

Pausing Yandex partnership

On March 1, 2022, in response to the Russian invasion of Ukraine, DuckDuckGo paused its partnership with Yandex Search.^[122] 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."^{[123][124][66]}

Blocking pirating websites

In April 2022, TorrentFreak reported that DuckDuckGo had blocked search results for some major pirating websites, including The Pirate Bay, 1337x and FMovies, as well as video downloading software Youtube-dl.^[125][126] In a statement to Engadget, 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 there were problems with "site:" search queries for these websites and other searches, and that the problem had been fixed.^[126]

Associations with Microsoft

In May 2022, a report from Bleeping 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.^[52][53] In August 2022, DuckDuckGo began blocking Microsoft's trackers, saying that the policy preventing them from doing so no longer applied.^[54]

Criticism of Google

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.^[127]
