Zen Browser

Zen Browser is a modern, privacy-focused web browser built on top of the Firefox engine. It was founded and developed as an open-source project to provide users with a clean, efficient, and highly customizable browsing experience that prioritizes user data protection and performance over traditional data-collection-heavy models.

While the project originated as an independent community-driven initiative, it has garnered significant attention for its unique vertical tabs layout and optimized browsing speed. As an open-source tool, it does not have a traditional manufacturing site; instead, its source code is developed and maintained by a global community of contributors, though its core leadership remains focused on maintaining its independence from large corporate tech conglomerates.
