I need a full-featured VPN application built for Android, iOS, and Windows. The core experience must feel identical on every platform: users pick a server, hit connect, and enjoy a secure, leak-free tunnel. Essential functionality • Server list that can be refreshed remotely, sorted by real-time ping, and filtered before connection • One-tap Server selection plus an Auto-connect option that obeys user rules (on app launch, on unsafe Wi-Fi, etc.) • Always-on Kill switch that survives network changes and guarantees zero traffic outside the tunnel • DNS management inside the app so I can point users to custom resolvers or a local blocker Protocol support OpenVPN (TCP & UDP), WireGuard, L2TP, and an HTTPS Proxy mode must be selectable per server or globally. Switching protocols should not force users to re-enter credentials. Deliverables 1. Store-ready builds: APK, TestFlight IPA, and a Windows installer 2. Complete, well-commented source code with build instructions 3. Lightweight branded UI (logo, colour palette, icons) 4. Admin guide explaining how to add or retire servers, edit DNS defaults, and trigger app updates 5. Two-week post-delivery bug-fix window Acceptance criteria The app connects on every listed protocol, maintains the tunnel through sleep/roam events, enforces the kill switch, and displays accurate ping values. Leak tests (IP, DNS, WebRTC) must all pass. If your previous work already integrates WireGuard and OpenVPN, the hand-over will be smoother, but clean, maintainable code is my top priority.

Hello, I have reviewed your VPN app requirements and understand the need for a consistent, secure cross-platform experience across Android, iOS, and Windows. With 10+ years of experience in mobile and network-based applications, I have worked with VPN integrations including WireGuard and OpenVPN. I can build a unified solution with protocol switching (OpenVPN TCP/UDP, WireGuard, L2TP, HTTPS Proxy), real-time server sync, ping-based sorting, auto-connect rules, and a robust kill switch to prevent leaks. My approach will ensure shared core logic with platform-specific implementations (Flutter/React Native + native modules or C++ core), secure credential handling, DNS control, and seamless reconnection across network changes. I will also implement leak protection (IP/DNS/WebRTC), background services, and efficient connection management. You will receive store-ready builds, complete source code, admin controls for server/DNS management, and full documentation with a walkthrough. I WILL PROVIDE 2 YEAR FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE, WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ZERO TO PUBLISHING ON STORES. I eagerly await your positive response. Thanks.

Hello, I understand you need a VPN app that works exactly the same on Android, iOS, and Windows. It should let users pick servers easily, connect fast, and keep data safe without leaks. The app must have a server list that updates remotely, sort by ping, and filter options, plus a simple one-tap connect or auto-connect based on user settings like unsafe Wi-Fi. It should keep a kill switch active always so no data leaks if the connection drops. DNS inside the app also lets you set custom or local blockers. The app must support OpenVPN, WireGuard, L2TP, and HTTPS proxy protocols, allowing users to switch without logging in again. I will deliver store-ready builds, clean code with instructions, a simple branded design, and an admin guide on managing servers and updates. After delivery, I’ll fix any bugs for two weeks. I focus on clean, reliable code and have experience with VPN protocols. What specific features or rules do you want for the auto-connect option? What branding elements or colour schemes do you prefer for the app UI? Are there preferred server locations you want included first? Do you already have backend infrastructure or servers set up for this app? Would you like me to include any analytics or usage tracking inside the app? What specific features or rules do you want for the auto-connect option? Thanks,

Hi there, I have read your project requirement. You need a full-featured cross-platform VPN application (Android, iOS, Windows) with consistent UX, multi-protocol support (OpenVPN, WireGuard, L2TP, HTTPS Proxy), real-time server management, auto-connect rules, kill switch, and DNS control, along with a scalable backend for server configuration. We can build this using Flutter for mobile + native modules (WireGuard/OpenVPN integration) and a Windows client (Electron or .NET), with secure architecture, optimised networking, and a centralised admin system for server/DNS management and updates. The app will be designed for stability, leak protection, and store compliance. Before proceeding, I have a few questions: =================================== Do you already have VPN servers configured (or need setup + recommendations)? Which authentication method will be used (username/password, certificates, tokens)? Do you need a subscription/payment system in this phase? What is your expected timeline for MVP launch? Best Regards, Srashtasoft Team

Hi, I’ve read your requirements carefully and you’re essentially building a cross-platform VPN product where reliability, security, and consistency across Android, iOS, and Windows are critical. The fact that you’re prioritising seamless protocol switching, a persistent kill switch, and accurate real-time server data tells me this needs to be engineered properly from the core not patched together. The server system will run on a remote config API, so you can update, sort, and filter servers in real time without pushing app updates. It will support both WireGuard and OpenVPN natively, with a shared login system so users can switch between them without signing in again. One thing I’d like to clarify is whether you already have VPN server infrastructure in place for OpenVPN and WireGuard configs, or if this also needs to be set up as part of the project. Also, do you plan to include user authentication accounts and subscriptions, or will access be managed externally? Let’s connect to align on architecture and get this moving in the right direction from day one. Thanks.

Hi I have solid experience building cross-platform network applications with Flutter, native mobile integrations, Windows desktop packaging, and secure backend-driven configuration management. The main technical challenge in a VPN project like this is not just connecting to multiple protocols, but keeping the tunnel stable across sleep, roaming, and network changes while guaranteeing no traffic leaks outside the secure path. I can solve that by designing a shared core architecture for server management, protocol handling, credential reuse, DNS control, and kill-switch enforcement, while using platform-specific network layers where Android, iOS, and Windows require lower-level control. I have worked with WireGuard-style flows, OpenVPN-based setups, API-driven server lists, and secure configuration delivery, so the app can keep the same user experience across all platforms. For this project, I would focus on clean, maintainable code, accurate real-time ping refresh, remote server updates, protocol switching without re-entry, and strict leak-prevention logic for IP, DNS, and WebRTC scenarios. I can also provide a lightweight branded UI, complete source code with build instructions, and an admin-friendly structure for adding or retiring servers and updating DNS defaults later. Thanks, Hercules
