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 MIT 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]
Legal status
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.
