Packaged bandwidth-bonding app for travelers and remote workers

What to build

A lightweight desktop app (Windows/Mac/Linux) that bonds a user's Wi-Fi, Ethernet, and phone/USB tether into one faster, more reliable connection, wrapping net-merge's open-source TUN/Wintun core in a simple installer and GUI, aimed at remote workers, RVers, rural users, and live streamers who need failover and combined bandwidth without buying a commercial bonding subscription.

net-merge proves the hard networking core (TUN/Wintun multi-adapter bonding) already exists and is open-source with real GitHub traction; the open opportunity is packaging it into a polished, installable consumer app that undercuts Speedify on price or offers a self-hosted alternative.

Demand

Remote workers, RV/boat travelers, rural broadband users, and live streamers chronically fight unreliable single-link internet and already pay for bonding tools like Speedify, showing willingness to pay for exactly this capability.

  1372 GitHub stars (Go), described as a tool for using all network adapters at once on Windows/Linux/Mac via per-connection load balancing over Wi-Fi, Ethernet and phone/USB tethers, using TUN/Wintun — high engagement at the source.

Stack

• net-merge (Go, TUN/Wintun core)
• Electron or Tauri for cross-platform GUI
• Wintun driver packaging for Windows installer
• WireGuard or custom UDP tunnel for optional cloud rendezvous server
• Stripe for subscription billing
• Simple VPS (Hetzner/DigitalOcean) for rendezvous/aggregation nodes

Solo + AI difficulty

Wrapping net-merge in a GUI and installer is tractable solo work with AI assistance (a few weeks), but standing up a reliable cloud rendezvous server for true multi-ISP bandwidth aggregation, handling driver signing/installer edge cases on Windows, and supporting live network failover are genuinely hard low-level networking problems that will dominate the timeline; realistic MVP (local multi-adapter bonding only, no cloud aggregation) is 4-6 weeks, with cloud bonding adding significantly more.

Entry threshold

Requires real networking and Go/systems skills to wrap TUN/Wintun drivers across Windows, Linux and macOS and to run a cloud rendezvous server for genuine multi-ISP aggregation, plus ongoing server costs; a solo technical builder could ship a usable product in a few weeks on top of the existing open-source core, but it is not a no-code weekend project.

Where to find first users

• r/homelab and r/HomeNetworking
• r/Rving and RV/boat travel forums
• live streaming communities (r/Twitch, streamer Discords)
• Show HN / Product Hunt launch positioning as a cheaper Speedify alternative

Competitors

• Speedify
• Connectify Speedify
• TP-Link OneMesh (unrelated bonding features)

Counter-signals & risks

• Speedify and similar established commercial bonding services already have mature multi-platform apps, mobile support, and cloud infrastructure, creating strong incumbent competition and switching-cost barriers for a new entrant.

• True multi-ISP bandwidth bonding requires a reliable cloud rendezvous/aggregation server with sufficient bandwidth and global points of presence, adding ongoing infrastructure cost and operational complexity not present in the open-source core.

• Building a polished GUI, installer, and subscription billing layer around a raw TUN/Wintun networking core is a substantial engineering and support effort that may be underestimated relative to the current state of the open-source project.
