Asil Browser

The first version of what became Kahf Browser: a family-safe browser built on Brave and Chromium, released under the Asil name.

Our part
We built the Brave-based browser released as Asil, and the work carried forward into Kahf Browser.

The client and the problem

The team that later launched Kahf wanted a family-safe browser of its own, first released under the Asil name.

What we built

We built Asil on Brave, which runs on Chromium. It was the first release of the project that continued as Kahf Browser, and the same client has kept working with us since.

  • A family-safe browser built on Brave and Chromium
  • The groundwork the Kahf Browser was later built on

Why it was hard

An early release sets the patterns everything later depends on: how custom code sits on top of Brave, how builds are produced and how updates ship. Those choices carried over when the product was renamed and grew into Kahf.

How it fits together

How Asil was put together

  1. Asil Browser

    The client’s product: the name and branding used before the project continued as Kahf Browser.

  2. Family-safe browser work

    The custom code that made Asil a family-safe browser, later carried into Kahf.

  3. Brave / Chromium

    • Brave
    • Chromium

    Built on Brave, which is itself based on Chromium.

  4. Desktop builds

    • Windows
    • macOS

    Platform-specific builds and release packaging for desktop.

  • Client's product
  • Our engineering
  • Upstream: third-party code we build on
  • Platforms and release
The Brave-based build sits on Brave and Chromium. The Android build used a separate Firefox for Android base, described below.

Outcome

  • The project continued as Kahf Browser, which Kahf reports has more than 280,000 active installations.

In the client’s words

“These guys are amazing. They are God Tier Fast and Efficient. I have worked with many developers, but these guys are the best. We have hired them for long-term engagement now.”

About the product

The product as its owner describes it. These are the client’s features, not a list of our work; our part is under “What we built”.

Asil Browser was an early browser from the team behind Kahf. Its public source code shows a build based on Brave, released under the Asil name, and the organization that hosts it is now called Kahf Browser.

According to the organization’s GitHub page, it published separate repositories for each platform: an Android build forked from Firefox for Android, an iOS build forked from Brave’s iOS browser, and a Chromium-based core alongside the original Brave-based one. A top-level “asil-browser” repository describes the product as a “Halal Asil browser for Android, macOS, Windows”.

The Asil organization on GitHub was marked archived in March 2025, so this page describes the browser as it was built, not a product you can download today.
