Sleipnir
Sleipnir is a Japanese web browser developed by Fenrir Inc., known for its advanced tab management and gesture-based navigation. The browser emphasizes UI customization, smooth tab switching, synchronized bookmarks, and refined interface design. It was historically popular as a feature-rich tabbed browser in Asia, particularly Japan, where it held a leading market share. The macOS version offered similar gesture controls and tab-centric browsing workflows as its Windows counterpart.
Suggested Replacements
1 suggestionSleipnir for macOS appears to have been discontinued or is no longer actively maintained. The developer's official website (fenrir-inc.com) focuses on Sleipnir 6 and 4 for Windows, along with Sleipnir Mobile for iOS and Android, but shows no current support or downloads for a Mac desktop version. Since Sleipnir for Mac is no longer available and receives no updates, you will need to switch to a native alternative. If you value tab management and gesture-based browsing, consider Safari (built into macOS and natively optimized for all M-series Macs), Arc (a modern gesture-friendly browser with excellent tab organization, available natively), or Chrome or Firefox (both ship Universal Binaries). All of these run natively on Apple Silicon and are actively maintained.
