GoodbyeDPI is a free and open-source software tool for bypassing deep packet inspection (DPI) systems and Internet censorship.[1][2] It was created by Russian developer ValdikSS in 2016 and is distributed under the Apache License via GitHub.[3]

History

GoodbyeDPI was first released in 2016 as an experimental tool to study DPI-based filtering in Russia.[4]

In 2024, the program gained wide popularity after the deliberate throttling of YouTube in Russia. Independent outlets reported it as one of the main tools used to circumvent restrictions.[5][6][7]

Technical overview

GoodbyeDPI uses the WinDivert library to intercept and modify network traffic at the Windows driver level.[8] It manipulates packets in ways that make DPI systems unable to properly recognize them, allowing access to blocked resources.[9]

Main techniques include:

  • fragmentation of TCP packets;
  • modification of HTTP headers;
  • SNI obfuscation in TLS sessions;
  • insertion of non-standard TCP flags.[10]

Usage

The program is distributed as a Windows console utility and configured via command-line parameters. Media reports and users describe it as effective for bypassing YouTube throttling and other restrictions.[6][11]

GoodbyeDPI has also been reported as used to bypass blocking of Telegram, LinkedIn and several foreign media outlets.[12]

The software is available only on Windows.[13]

Reception

  • Meduza reported that the tool helps to bypass YouTube throttling but requires careful setup and may interfere with some services.[14][15]
  • The Insider noted its rising popularity and warned of fake builds spreading online.[4]
  • Research by OONI has cited GoodByeDPI as an example of client-side packet segmentation tools used to evade filtering.[16][17]

While direct penalties for end users have not been documented, Russian law empowers Roskomnadzor to block sites distributing circumvention software or instructions, including VPNs and DPI bypass tools.
