I Built an Open-Source Tool That Turns Websites Into Android Apps

Hey everyone!

I’ve been working on a project called InteeBuild.

The idea is pretty simple:

Give it a public website or HTML and get an Android project/APK/AAB without having to manually set everything up.

What can it do?

InteeBuild currently supports things like:

• Website → Android app
• HTML → Android app
• APK / AAB builds
• Custom app name and package
• Custom icons
• Android permissions
• Background audio
• Native bridges
• GitHub Actions builds
• Build artifacts
• Build logs
• API access
• Webhooks
• APK inspection/decompilation
• Security checks for URLs and webhooks

One of the parts I spent the most time on was the permission system.

Instead of simply adding permissions to the manifest, InteeBuild keeps information about whether a permission requires runtime access, special Android settings, dependencies, minimum SDK versions, etc.

Security

Since the server can receive URLs and APK files, I also added protections against things like:

• SSRF
• localhost/private IP access
• cloud metadata endpoints
• malicious ZIP/APK structures
• oversized inputs
• API abuse
• invalid webhooks
• rate-limit abuse

There are also automated tests for many of these cases.

Why did I make it?

I wanted something that could take a website and make the Android side much less annoying.

There are already many tools that do something similar, but I wanted InteeBuild to be more transparent about what is actually generated and what still requires native implementation.

For example, adding a permission to Android's manifest doesn't magically make the website capable of using that hardware.

So the project tries to distinguish between:

declared → supported → generated → actually usable

What's next?

Right now I'm focusing more on stability and security instead of just adding more features.

I want the core pipeline to be reliable:

URL/HTML → Analyze → Configure → Audit → Build → APK/AAB

I'd love to hear feedback from other developers.
