What Is ProPublica’s .onion Address?
ProPublica launched its .onion hidden service in 2016 — becoming the first major news organization in the world to establish an official presence on the Tor network. It predates the BBC’s .onion by three years and the New York Times’ by one year, making it the pioneer of news .onion addresses.
ProPublica is an independent nonprofit investigative newsroom funded by the Sandler Foundation and similar organizations. It accepts no advertising and charges no subscription fees — all of its journalism is free to read. Its .onion address extends that commitment to universal access by making its journalism available in countries where propublica.org is blocked or monitored.
Onion Address
Clearnet version: https://propublica.org
Verification: This address was announced by ProPublica in January 2016 and is referenced in the Tor Project’s documentation as an example of legitimate news .onion usage. It has remained stable since launch.
Why ProPublica Launched a .onion First
ProPublica’s decision to launch a .onion address in 2016 was ahead of its time. At the point of launch, most mainstream organizations viewed Tor as a tool associated exclusively with criminal activity. ProPublica took a different view — that Tor was a legitimate privacy tool used by journalists, activists, whistleblowers and ordinary people trying to protect themselves from surveillance.
The stated reason was straightforward: ProPublica’s journalism covers topics — government corruption, corporate wrongdoing, surveillance, civil rights — that are precisely the topics that authoritarian governments most want to suppress. Readers in those countries needed a way to access that journalism without risk. A .onion address provided it.
ProPublica also operates a SecureDrop instance — making it one of the most comprehensively privacy-equipped news organizations operating anywhere. Sources can submit documents anonymously via SecureDrop, read the resulting journalism via the .onion address and communicate with journalists via PGP-encrypted email, all without leaving a traceable record.
What ProPublica Covers

How to Access ProPublica via Tor
- Download Tor Browser from torproject.org
- Set security level to Safest — ProPublica’s site functions well with JavaScript disabled
- Paste the .onion address into the address bar
- Browse freely — no account, no paywall, no subscription required
ProPublica is one of the few major news organizations whose .onion works well in Safest mode. Its relatively simple page design functions without JavaScript — a meaningful advantage over heavier sites like the NYT or BBC that require JavaScript for full functionality.

ProPublica’s Pulitzer Prizes
ProPublica has won more than a dozen Pulitzer Prizes since its founding in 2008 — more than most newspapers that have been publishing for over a century. It was the first online-only publication to win a Pulitzer Prize for Investigative Reporting, which it received in 2010. This track record makes it one of the most credentialed investigative outlets operating anywhere in the world, online or offline.
For readers using the .onion address to access journalism they cannot reach through clearnet channels, ProPublica’s award history is a meaningful signal of editorial credibility — you are reading verified, independently produced investigative journalism, not content of uncertain provenance.
Submitting Documents to ProPublica
ProPublica runs a SecureDrop instance for anonymous document submissions. If you have information relevant to ProPublica’s coverage areas — government corruption, corporate wrongdoing, criminal justice — you can submit it anonymously via SecureDrop without revealing your identity.
ProPublica’s SecureDrop address is listed in the SecureDrop directory:
Navigate to the directory and find ProPublica’s specific SecureDrop address. Strip metadata from all documents before uploading. Use Tails OS for maximum protection if the stakes are high.
Why ProPublica Is Particularly Valuable on the Dark Web
Most news organizations that operate .onion addresses are primarily motivated by censorship circumvention — getting their journalism to readers in countries where they are blocked. ProPublica shares that motivation but adds a second dimension.
Its coverage topics — government surveillance, law enforcement misconduct, corporate fraud — are precisely the topics that create risk for readers in surveillance-heavy environments. A person reading a ProPublica investigation into police misconduct or government corruption may have specific reason to want that reading activity to be private, independent of whether they live in a censored country.
The combination of fully free content, no advertising, functional Safest mode and a strong investigative track record makes ProPublica’s .onion one of the most practically useful news addresses on the dark web.
Frequently Asked Questions
Is ProPublica’s content really free?
Yes — completely. ProPublica is funded by philanthropic donations and has never had a paywall. All articles, investigations and data tools are free to read on both the clearnet site and the .onion address. No account is required.
Why does ProPublica work better in Safest mode than other news sites?
ProPublica’s web design is relatively lean compared to commercial news sites. It does not rely heavily on JavaScript for core reading functionality — articles load and display correctly even with JavaScript disabled. This makes it one of the few major news sites that works well in Tor Browser’s most secure configuration.
Is ProPublica blocked anywhere?
ProPublica is not subject to the widespread national-level blocking that affects BBC or NYT in China. However, it covers topics — government corruption, surveillance, immigration enforcement — that may attract monitoring by employers, governments or other parties in various contexts. The .onion address provides protection against that monitoring regardless of whether ProPublica itself is blocked.
How does ProPublica’s nonprofit status affect its journalism?
ProPublica’s nonprofit structure means it has no advertising clients to protect and no shareholders demanding profitable coverage decisions. Its journalism is funded by donors who explicitly support investigative reporting. This independence is why it is able to publish investigations that directly challenge powerful institutions — the financial model does not create conflicts of interest with those institutions.
Can I donate to ProPublica via the .onion?
Yes — the .onion version includes ProPublica’s donation functionality. Donating via the .onion hides your IP from ProPublica’s servers but donation payment methods (credit card, PayPal) will still link your identity to the donation through the payment processor. For anonymous donations, cryptocurrency options may be available — check ProPublica’s current donation page.
