Show HN: Ghostty-based Terminal with Vertical Tabs and Notifications - A New Development

This news item, published on February 19, 2026, on Hacker News, announces a new terminal application. The project, titled 'Ghostty-based terminal with vertical tabs and notifications,' is available on GitHub under the URL https://github.com/manaflow-ai/cmux. The original content provided only 'Comments,' indicating that the announcement is likely a 'Show HN' post, inviting community feedback and discussion on the new terminal's features, specifically its vertical tabs and notification capabilities. A 'Show HN' post on Hacker News is typically used by developers to present their new projects to the community, seeking initial impressions, bug reports, and suggestions for improvement. While the specific details of the terminal's implementation, such as the programming language used, its performance metrics, or a comprehensive list of features beyond vertical tabs and notifications, are not provided in the original text, the title itself highlights two key user interface and experience enhancements. Vertical tabs can improve workflow for users managing many open terminal sessions, offering better screen real estate utilization compared to traditional horizontal tabs. Notifications could provide timely alerts for long-running processes or specific events within the terminal, enhancing user productivity. The project's presence on GitHub suggests it is open-source, allowing for community contributions and transparency in its development. The lack of further descriptive content beyond 'Comments' implies that the initial announcement was brief, possibly serving as a direct link to the GitHub repository for those interested in exploring the project further or engaging in discussion.
