Zen and Yalqen are both open-source Mac browsers that put tabs in a side panel, and Zen presents itself as a successor to Arc. The biggest difference is the engine underneath.
Zen is a Firefox fork with workspaces and split view. Yalqen is Chromium-based, so it matches Chrome for site compatibility and DevTools, but it has neither workspaces nor split view yet.
What feels the same
- Open source, free and made for people who want a calmer, tab-first browser.
- A vertical tab panel that can sit on either side.
What Yalqen does differently
- Chromium engine, the same as Chrome, so sites built for Chrome behave the same and the full Chromium DevTools are built in.
- Chrome extensions from the Chrome Web Store, where Zen uses Firefox add-ons.
- A keyboard-first command bar on ⌘L that runs commands by name.
- Developer tools built in: phone view with device presets, network throttling, request rules and screenshots.
- Ad blocking from the first launch, and third-party cookie blocking, HTTPS-only mode and secure DNS one switch away in settings.
Where Zen is ahead
- Zen has workspaces and split view. Yalqen has neither yet.
- Zen runs on Windows, macOS and Linux. Yalqen is macOS 13+ on Apple silicon only.
- Firefox add-ons are fully supported in Zen, while Chrome extensions work in Yalqen with limits.
- Zen has a community theme collection and more ways to customise its look.

Try it next to Zen
Yalqen does not need to replace your current browser to be worth a try. Install it, learn the keyboard shortcuts and see whether the layout suits you. Missing something? Open an issue, and see what is coming on the roadmap.
