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

Overview

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.

GitHub: https://github.com/Fluxionics/InteeBuild

Features

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

Permission System

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 It Was Built

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.
