I’m looking for a lightweight, browser-based audio-conferencing application that creates five simultaneous audio channels—one host channel that drives the discussion and four guest channels that respond. Interface 1 (host): opens in a browser, starts a session, generates join links, and sees live controls for every channel. Interface 2 (guest): is simply the link each guest opens to join the conversation. Essential channel controls • Mute / un-mute • Accept / reject incoming audio • Individual volume fader • Echo cancellation and automatic mic gain Chat panel • Room-wide text messaging • Small file sharing (e.g., PDF, images) Security • Basic user authentication for both host and guests. Tech notes • WebRTC with an SFU; I rely on you to recommend and configure the optimal TURN/STUN setup for low latency and reliability. • Must run efficiently on a small device; either Linux or Windows is acceptable. • Feel free to leverage lightweight frameworks such as mediasoup, Janus, livekit or Jitsi if they meet the resource target. I am not sure if cloudflare maybe used but ideally will want all open source. What I will provide • A simple prototype mock-up of the intended UI. What I need from you 1. A functional minimum-viable app that matches the prototype. 2. Source code, server configs, and build scripts. 3. A concise deployment guide so I can install and run it on the target device. If you have questions or see a smarter way to hit the latency/reliability balance, please outline it in your proposal.
