🚀 Busco ayuda para crear una VPN gratuita desde cero

General Discussion
1

Hola comunidad.

Soy un principiante en el desarrollo de aplicaciones y actualmente estoy dando mis primeros pasos en MIT App Inventor. Tengo una idea que me entusiasma muchísimo: aprender y desarrollar una VPN gratuita desde cero. Sin embargo, reconozco que mis conocimientos aún son muy básicos y por eso necesito la ayuda de personas con más experiencia.

No estoy buscando que alguien haga el proyecto por mí. Lo que realmente quiero es aprender, entender cómo funciona una VPN, conocer las tecnologías necesarias y recibir orientación para avanzar paso a paso. Estoy dispuesto a estudiar, investigar y dedicar el tiempo que sea necesario para hacerlo realidad.

Si alguien tiene experiencia en redes, servidores, seguridad informática, VPN, App Inventor o cualquier tema relacionado, agradecería enormemente cualquier consejo, guía, recurso, documentación, tutorial o recomendación. Incluso una pequeña orientación puede ayudarme a evitar muchos errores y acelerar mi aprendizaje.

Sé que crear una VPN es un proyecto ambicioso y complejo, pero también sé que las grandes metas comienzan con los primeros pasos. Por eso recurro a esta comunidad, porque sé que aquí hay personas con conocimientos y experiencia que pueden ayudar a quienes estamos empezando.

Muchas gracias por tomarse el tiempo de leer este mensaje. Cualquier ayuda, sugerencia o aporte será recibido con muchísimo agradecimiento.

¡Gracias de corazón y espero aprender junto a ustedes! :folded_hands:

Hi there!
Welcome to the community, and congratulations on taking your first steps into app development! Your enthusiasm, dedication to learning, and realistic outlook on the complexity of this project are highly commendable. Building a VPN from scratch is an incredible learning goal.

However, this specific community is not the best place to find the technical guidance you need, and here is why:

  • Scope of MIT App Inventor: App Inventor is designed as an entry-level block programming language. It abstracts away low-level networking, protocols, and system-level architectures. Building a VPN client requires deep access to the Android Operating System's internal network stack, which standard App Inventor components do not support.

  • The "Two-Part" Problem: A VPN is not just an app; it is a client-server infrastructure. The community here focuses almost entirely on the client side (the app), whereas 90% of a VPN's core logic, encryption, and routing happen on a remote server, which requires completely different technologies.

To build a VPN, you will need to step outside of App Inventor. Here is a short overview of the technologies you should start researching to make this project a reality:

1. Server Infrastructure

You cannot have a VPN without a server to route traffic through.

  • VPS (Virtual Private Server): You will need to rent a cheap cloud server (from providers like DigitalOcean, Linode, or AWS) to act as your VPN gateway.

  • Linux: You will need to learn basic Linux command-line administration, as almost all VPN servers run on Linux.

2. VPN Protocols (The Core Technology)

Instead of writing encryption algorithms from scratch (which is highly discouraged for security reasons), you should use established, open-source protocols:

  • WireGuard: Modern, fast, and uses a much smaller codebase. This is highly recommended for beginners because it is easier to understand and set up.

  • OpenVPN: The industry standard, highly secure, but has a steeper learning curve.

3. Client App Development

To interact with these protocols at a system level on a mobile device, you will eventually need to move to professional development environments:

  • Android Studio (Java/Kotlin): Android provides a specific VpnService class that allows applications to manage their own VPN connections. Utilizing this requires native Android development, or at the very least, creating a highly complex custom Java extension if you absolutely insist on using App Inventor.

  • Flutter or React Native: Good alternatives if you want to build cross-platform apps (Android and iOS) later on.

Next Steps for Your Journey

Don't let the scale of this project discourage you! Every expert started exactly where you are now. To bridge the gap, we highly recommend posting your question in communities dedicated to broader networking and development, such as:

  • Reddit: r/networks, r/VPN, or r/learnprogramming

  • Stack Overflow (once you have specific code or configuration questions)

Start by learning how to set up a basic WireGuard server on a computer at home, connect to it using the official WireGuard app, and then work your way up to building your own client interface.

Wishing you the best of luck on your development journey!
