Tor is Powered by you: One donation today can impact 4M+ people

2026-10-13T00:00:00Z

Unlike Big Tech, Tor has never and will never sell your data to make money. 6,490 donors, and thousands of volunteer relay operators and others, keep Tor powered for 4M+ at any given moment* at zero cost to users.

You can ensure people worldwide can exercise their human rights to digital privacy and access to information by making a donation today. Every donation, of any size, makes a difference.

As a 501(c)(3) nonprofit, the Tor Project relies on donations to power its tools – the Tor network, Tor Browser, Tails OS, and the Tor ecosystem. These tools are trusted by millions and always free to use, without collecting, selling, trading, or renting any of your data for profit. Read our 2023-2024 financials to be confident your investment is being stewarded with the utmost importance.

In the last year we have reached some major milestones thanks to your support:

Tor VPN beta extends Tor protections beyond the browser. It offers device-level network protection on Android, helping bring Tor's protections to messaging apps, social media, email, and other mobile services of a user's choosing. Learn more about what makes our per-app isolation different from commercial VPNs, the surprising UX lesson when trying to bypass blocks, and the mobile foundation we're building for what's next.
Privacy Resilience Grants: Dispersed $23,201 to support 8 Tor partners in conducting Tor activities on the ground. Among these groups, women activists in Bolivia have adopted Tor tools, shifting the thinking of using other tools for power and resistance. Meanwhile, journalists in Afghanistan have reduced their reliance on VPNs, and have begun using Tails OS to securely share on the ground information globally.
Funding internet freedom: Our first crowdfunding round in partnership with Funding the Commons raised more than $200k for projects working across privacy, censorship circumvention, secure communications, and public-interest digital infrastructure. This is Tor’s first attempt at building a new funding infrastructure for the internet freedom community.

All of these major milestones have a real life impact on people globally. People who need privacy for their safety, people who rely on Tor tools to be connected to the world, and people who are casual users seeking an alternative to Big Tech.

“The police state is vigorously spying on people. Without Tor we would be shut off from the world, no one hearing our voice.”

– Iranian Tor user**

“I desperately needed a means to secure my online privacy because I am a cyberstalking victim. I started using Tor to protect my privacy and protect me from abuse.”

– Anonymous Tor user**

A statement on the Tor Project's relationship with Mullvad

2026-10-09T00:00:00Z

Recent concerns about a political donation by a Mullvad co-founder have raised questions about the Tor Project's funding relationship with the company. We are not terminating the relationship but are setting clear boundaries on our relationship with Mullvad.

Members of the Tor community have asked us to explain how continued collaboration with Mullvad fits with the Tor Project's human rights mission. We have heard both calls to end the relationship and concerns about what that would mean for Tor's work and the communities affected. We want to explain our decision to continue our technical collaboration with Mullvad and acknowledge the difficult trade-offs behind it. Our decision followed a thorough due diligence process that involved extensive discussions with community members, staff, and the board, a staff survey, and detailed financial analysis and scenario planning.

The Tor Project’s mission is to advance human rights and freedoms. We build privacy and anti-censorship tools that people use to protect themselves from repression and surveillance, and express themselves freely. We will continue this work alongside communities whose rights are under threat.

While Tor defends free speech, not all speech is equally compatible with our mission. We strongly oppose rhetoric that threatens other human rights and freedoms.

The work to promote and preserve the human right to privacy, free speech, and free access to information online is severely under-resourced. This work requires and benefits from collaboration across organizations. Sometimes that work requires making difficult compromises to advance specific goals we know will benefit our communities in the long run.

We are continuing our technical collaboration with Mullvad to sustain work that Tor users and contributors depend on. This collaboration has helped improve the structure, maintainability, and auditability of Tor Browser’s codebase, expanded feedback from users beyond Tor Browser’s core audience, and created a lower-risk environment to test features that may later benefit Tor Browser users. It also gives more people access to online privacy through an additional free, open-source tool that serves different user needs. We recognize that the potential benefits to Mullvad of such a collaboration are difficult for some in our community to accept. Our responsibility is to ensure that this collaboration does not compromise our mission or the Tor Project's independence.

Tor Project has paused proactive co-branding with Mullvad. That pause applies to joint promotional activity while the technical collaboration continues in alignment with our narrowly scoped agreement. We have also reviewed how Mullvad Browser is described and endorsed on our owned channels, and clarified language suggesting broader alignment between our values. These changes are intended to describe the relationship more accurately and avoid notions of implied endorsement.

We know this decision will not satisfy everyone. Continuing the collaboration carries a cost to trust for some in our community, and we take that seriously. We are grateful to the members of our community who have raised concerns, asked hard questions, and reminded us what is at stake. Those concerns are shaping our path forward. Tor’s mission has always required both principle and pragmatism. We will continue to defend privacy, anonymity, freedom of expression, and access to information while making clear that our collaborations must serve, and never obscure, our human rights commitments.

Arti 2.7.0 released

2026-10-01T00:00:00Z

Arti is our ongoing project to create a next-generation Tor implementation in Rust. We're happy to announce the latest release, Arti 2.7.0.

This release continues our ongoing development towards using Arti as a relay and as a directory authority, with much of the work focusing on document parsing, directory mirror support, and DNS stream handling. Additionally, arti now has RPC support for modifying and inspecting its configuration.

This release has a number of fixes for low- to high-severity security issues. We encourage arti, arti-client, and arti-ureq users, especially those running onion services, to upgrade as soon as possible.

As usual, there also are many under-the-hood improvements to our infrastructure, testing, and documentation, along with multiple bug fixes and internal cleanups.

For full details on what we've done, including API changes, security fixes, and for information about many more minor and less-visible changes, please see the CHANGELOG.

For more information on using Arti, see our top-level README, and the documentation for the arti binary.

Thanks to everybody who's contributed to this release, including Gaith Hallak, iqdecay, manthan-lab, and pryty26.

Also, our deep thanks to our sponsors for funding the development of Arti!

New Release: Tor Browser 15.0.24

2026-09-29T00:00:00Z

Tor Browser 15.0.24 is now available from the Tor Browser download page and also from our distribution directory.

This version includes important security updates to Firefox.

Windows Package Signature Issue

The DigiCert EV code-signing certificate we use to sign Windows installation packages is expired since September 1st and we are currently in the process to renew it. Unfortunately, this process is delayed and not yet complete.

This has caused Windows users trying to install Tor Browser 15.0.21 and 15.0.22 from scratch to receive "bad signature" warnings.

As a temporary work-around, for Windows only we're keeping Tor Browser 15.0.20 (the latest correctly signed version) listed on our download page, relying on automatic updates (which are signed with a different key, not involving this expired certificate) to bring Windows users to the current version.

Users who prefer to download the latest version directly, ignoring the certificate expiration warning, can download it from https://dist.torproject.org/torbrowser/15.0.24/.

New PGP subkey

This release is signed using a new subkey. If you previously used gpg to verify Tor Browser downloads, you may need to refresh the Tor Browser signing key (0xEF6E286DDA85EA2A4BA7DE684E2C6E8793298290) in your local keyring. For more details you can read our page about signature verification, specifically the section "Refreshing the PGP key".

If you find a bug or have a suggestion for how we could improve this release, please let us know.
