THOUGHTFUL BY DESIGN
Rust gives us control over how our apps use your device. The details make the difference.
Both apps use Rust for their desktop core. Yas Mail uses Tauri; Yas Browser uses Tao and Wry. Purposeful foundations for everyday tools.
Rust · Native desktopYas Browser loads restored tabs on demand and unloads eligible background pages after two minutes. Your saved tab URLs remain ready to reopen.
Lazy restore · Sleeping tabsOn Windows, both apps use WebView2. Yas Browser’s Rust application runs on Microsoft’s web engine; it doesn’t ship a separately bundled Chromium engine.
Windows WebView2Cross-app RAM and CPU comparisons are being evaluated. We’ll publish repeatable tests before making a percentage claim. Rust alone doesn’t guarantee lower resource use; websites and workloads matter.

Just your existing email. No new mailbox. No account needed.A FEW THINGS TO KNOW
Yes. The current Windows previews are free to download and try. You don’t need to register your email to download them.
Yes. Both apps have a Rust desktop core. Yas Mail uses Tauri 2; Yas Browser uses Tao and Wry. On Windows, web rendering is handled by Microsoft Edge WebView2, rather than a new rendering engine written entirely in Rust.
macOS is on the roadmap. Both applications currently have Windows-specific components that need porting and testing. Register above and select macOS to hear when a build is ready. We haven’t announced a release date.
Publisher configuration and live verification of Gmail, Outlook, and Microsoft 365 sign-in are still in progress. The downloadable preview has a demo workspace and manual account setup. Manual setup depends on your provider’s supported protocols and authentication rules.
We’re preparing signed, versioned releases. Yas Mail’s development source includes Tauri updater integration, but public update feeds and signing configuration are not live yet. Yas Browser needs its updater integration. For now, download the current installer here.
The Windows preview source is public: Yas Browser on GitHub and Yas Mail on GitHub. Yas-owned code uses the MIT license; third-party components retain their own licenses. Each repository includes contribution guidance and an issue tracker.
