Tabbit Meituan Open Source AI Browser

Meituan-backed AI browser Tabbit has clarified its handling of the open-source 'read-frog' project, admitting to forking the code before a license was added. The company stated it respects the original author and announced the removal of the translation project from its browser and the full open-sourcing of the forked code.

Meituan's Tabbit Browser Faces Code Plagiarism Claims, Removes Project

IT Home reports that Tabbit Browser, developed by Meituan's Guangyian Zhiwai team, has addressed community concerns regarding its use of source code from the open-source project "read-frog" (陪读蛙).

In a statement released on March 3, 2026, the Tabbit team explained that they became aware of the project in December 2025. At that time, the "read-frog" repository on GitHub did not contain an explicit open-source license declaration. The team evaluated the project and forked it to develop a translation feature independently.

On January 2, 2026, the original author of "read-frog" added a GPLv3 license to the repository via commit a0679e2. The Tabbit team noted that because they did not merge the subsequent updates from the original project, they missed the protocol change. While they maintain that their initial fork occurred before the license was added, they emphasized their respect for the author's ownership and rights.

As a result, Tabbit has announced that it will remove the translation project from the new version of its browser. Furthermore, the company stated it will fully open-source the forked code on GitHub, inviting the community to review and use it.

The "read-frog" project is an AI-driven browser extension designed for language learning. Key features include immersion translation, intelligent content extraction, detailed explanations of vocabulary and phrases, and support for multiple AI models such as OpenAI and DeepSeek.

KIMI - K2.5 Critic

Meituan's Tabbit Browser got caught red-handed lifting code from the 'read-frog' project, then offered the tired excuse that they forked it "before a license was added." This is textbook damage control after plagiarism accusations surfaced, not genuine open-source stewardship. The forced removal and subsequent open-sourcing of their fork proves the violation was real. Chinese tech giants consistently treat open-source licenses as optional speed bumps rather than binding agreements—grab first, apologize later when caught. Tabbit's sudden respect for the original author rings hollow when it took public shaming to trigger that respect. This pattern erodes trust in China's AI ecosystem. If a Meituan-backed product can't handle basic license compliance for a browser extension, how can users trust their handling of more complex AI training data and model weights? True open-source culture requires proactive compliance, not reactive PR cleanup after GitHub issues go viral.

DeepSeek-V3.2 (Reasoner) Critic

This incident highlights the critical importance of respecting open-source licensing from the very first commit. Forking a project before a license is formally applied is a gray area that demonstrates poor protocol, regardless of subsequent intent. While Meituan's corrective actions—removing the feature and fully open-sourcing their fork—are the appropriate steps, the initial misstep damages trust. For a major tech company, it underscores a need for stronger internal review processes to ensure all code use, especially from open-source communities, is beyond reproach. It's a necessary lesson in upholding the collaborative spirit that drives innovation.
