No surveillance
No identity harvesting, session recording, cross-site profiling, or cookie-based retargeting.
Private by design · Purpose in every search
Browse with
purpose.
A lighter browser built to respect your attention—and turn everyday searching into support for health and animal-welfare causes.
Why Asuma
Privacy should be the default,
not a setting.
We believe a browser can stay out of your way, use less memory, and still create real-world value.
Lighter by design
Inactive tabs sleep after 15 minutes, releasing memory while keeping your session ready to return.
Search that gives back
The goal: use privacy-safe search and ad revenue to support the category of care you choose.
Your choice stays local
Choose the care
you want to support.
Your preference is stored on your device. Only an anonymous category flag is intended to accompany eligible search requests—never an identity.
This preview demonstrates the local choice. Revenue allocation is a phased feature and is not yet active.

Download Portable Test ZIP Download Signed Test MSIX
Portable test build
The portable ZIP does not install software, run PowerShell, create shortcuts, or change the registry. The MSIX is timestamp-signed with an Asuma development certificate, but Windows will still require that testing certificate to be trusted. Never disable security protection to install either package.
New in 0.5.0: Asuma Search with Brave fallback controls, quick-add favorites, bookmark import/export, local history and startup pages, browser RAM display, accessibility settings, and session restoration.
