I HAVE BUILT OFFLINE P2P WEBRTC SYSTEMS — READY TO DELIVER YOUR LOCAL VIDEO CALL MVP WITHOUT INTERNET. Hello, I can develop your offline-capable mobile app enabling 1:1 voice and video calls over a local Wi-Fi mesh, with a lightweight signaling server to coordinate call setup via SDP/ICE exchange. Technical Approach Mobile App: Kotlin (Android) + WebRTC native stack for real-time audio/video Signaling Server: Node.js or Go service running locally (Docker/Linux), handling registrations, presence, call invitations, and ICE/SDP exchange over WebSockets Discovery: mDNS / Bonjour for automatic LAN detection, fallback to gateway Offline Operation: Fully P2P; no cloud, SFU, or media relay User Flow: Register → discover peers → initiate/receive calls by name Deliverables Android app (APK + source); optional iOS version Local signaling server with deployment instructions Documentation: discovery process, server deployment, offline testing Demo: two phones connect via Wi-Fi, discover each other, place a video call offline User Roles User: Register, discover peers, make/receive calls Admin/Operator: Deploy signaling server, manage network if needed You will also receive 2 years of free support for troubleshooting and minor enhancements. I can provide a fixed-cost estimate and timeline once we confirm device count, iOS inclusion, and testing scope.

Hi The core technical challenge is enabling reliable 1:1 voice and video calling with WebRTC when there is zero internet connectivity and no cloud infrastructure available. I have strong experience with native WebRTC stacks, offline-first mobile networking, and LAN-based discovery mechanisms such as mDNS and fallback gateway resolution. I can design an Android-first solution that auto-discovers a local signaling service, registers user identities, and maintains presence even during IP changes. The signaling layer will strictly handle SDP and ICE exchange over WebSockets while keeping all audio and video streams fully peer-to-peer. I will ensure users can discover peers by name, initiate calls seamlessly, and reconnect cleanly without media interruption. The implementation will be lightweight, secure, and deployable on local Linux or router hardware with clear documentation. This approach delivers a true offline video calling system that functions entirely within a local Wi-Fi mesh. Thanks, Hercules

With a blend of my deep expertise in mobile app development, Android, and Node.js, I am confident in my ability to create your Offline Local Video Calling App. Building offline capabilities is a challenge but I assure you that I am comfortable delivering high-quality projects with such intricate requirements. Although Unity Game Development and creating captivating gaming experiences have largely occupied my career, the uniqueness of this project caught my attention - the opportunity to challenge boundaries beyond the traditional and disruptive! I noticed that you preferred WebRTC in your stack, which fortuitously aligns with my extensive knowledge in utilizing Kotlin (Android) and working extensively with WebRTC native stack. My skills in productively fusing these technologies will ensure seamless 1:1 voice + video calls even without internet or cellular backhaul. Additionally, I possess a strong command over Linux which I believe will come in handy for hosting your local signaling server efficiently powering your project in challenging offline networks. Furthermore, as an AR/VR pioneer, adapting cutting-edge technology and pushing its limits is something deeply ingrained in me. Importantly, it is craftsmanship like mine that can be vouchsafed not just for delivering standard functionalities like user identification or live feed rendering over P2P communication but also ensuring uninterrupted discovery and call setup irrespective of IP changes or reconnections.

@mughiraaa

Hello, I have reviewed the details of your project. i will create a mobile app for android using kotlin that uses the native webrtc stack for 1:1 voice and video calls. the app will connect to a local signaling server over websocket and discover it automatically using mdns, with a fallback to a static gateway if needed. each device registers with a unique name and device id, and the app maintains a list of online users provided by the server. when a user initiates a call, the signaling server forwards the sdp and ice candidates to the target device, enabling direct peer-to-peer media exchange over webrtc. the signaling server will run as a lightweight node.js service inside docker or on a small linux device, handling registration, presence, call invitations, and metadata exchange. the app will automatically handle ip changes and reconnections. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you. Thanks Best Regards, Mughira

@mykhaylob4

✋ Hi there. I can build your offline P2P video calling app to run entirely over a local Wi-Fi mesh, enabling Android devices to discover each other and make secure 1:1 WebRTC calls without any internet or cloud dependency. ✔️ I have strong experience with WebRTC, P2P media streams, and offline discovery using mDNS/Bonjour. I’ve built mobile apps that communicate over local networks with custom signaling servers, handling user registration, presence, and SDP/ICE exchanges reliably in dynamic LAN environments. ✔️ For your project, I will develop an Android app that performs direct video and audio calls via WebRTC, integrates a simple local signaling server (Dockerized or Linux service), and implements automatic device discovery and user identity management. Users will see online peers by name and initiate calls without needing IP addresses. ✔️ I will provide complete source code, the APK, the signaling server, and a demo showing two phones connecting and placing a video call offline. Documentation will cover deployment, testing, and how the discovery mechanism works, ensuring you can replicate or extend the system in the future. Let’s discuss timelines and get this offline communication MVP working seamlessly. Best regards, Mykhaylo

@mahig47

Hello! As per your project post, you are looking to build an offline peer to peer video calling mobile application as a proof of concept that operates entirely without internet or cellular connectivity. The objective is to enable Android first and optionally iOS devices to discover each other over a local Wi Fi network and place one to one voice and video calls using a purely local WebRTC based architecture. My focus will be on delivering a true offline first communication solution where device discovery, user presence, and call setup all function reliably within a local LAN. This includes implementing mDNS based service discovery with fallback handling, a lightweight local signaling server for SDP and ICE exchange, and direct peer to peer media flow with no cloud dependency. I specialize in real time communication systems and native mobile development with strong experience in WebRTC internals, local signaling architectures, and network constrained environments. My approach emphasizes clean separation between signaling and media, native WebRTC integration on Android using Kotlin, and a simple but resilient signaling service built in Node.js or Go that is easy to deploy on a router or Linux device. Let’s connect to align expectations and ensure this offline video calling MVP proves reliable peer to peer communication with zero internet dependency. Best regards, Nikita Gupta.

@kareemmaize

Hi there, To make an offline local video calling system work, the most critical part is local signaling and discovery, not the media itself. WebRTC handles P2P audio/video well, but only if identity, presence, and SDP exchange are rock solid without the internet. I’ll build an Android-first MVP using the native WebRTC stack, paired with a lightweight local signaling server (Node.js or Go) that runs on a router or Linux box. Devices will auto-discover the server via mDNS with a fallback, register a human-readable identity, show online peers, and place 1:1 calls entirely over local Wi-Fi. The server will coordinate presence and signaling only—no media relay. I’ve worked on real-time and offline-capable systems where networking edge cases mattered more than UI polish. That experience means I focus on reconnection handling, ICE stability on LAN, and predictable call setup flows. Delivery will include the mobile app, local signaling service, clear deployment docs, and a repeatable offline demo scenario with two devices calling successfully.
