OpenMPTCProuter is an open-source project that aggregates internet connections using Multipath TCP on an OpenWrt router, paired with a server a business runs itself on a VPS. It is free and can genuinely combine Starlink with 4G/5G cellular and wired links.
Speedify bonds the same connections as a supported commercial product, on devices a business already owns, with the operational guarantees a business depends on. This post compares the two for a Starlink-first business.

Quick answer
Should you get a backup connection for Starlink?
Yes. Starlink goes down every day — an always-on dish averages about 34 minutes of downtime daily from routine satellite handoffs. A second connection keeps you online when Starlink drops.
What’s the best backup connection for Starlink?
A 4G/5G cellular hotspot or SIM is the most practical backup for most Starlink users — it works anywhere Starlink works, requires no installation, and uses a different network so outages rarely overlap. Cable or DSL broadband is a strong option if you have it at a fixed location. A second Starlink dish is also possible if you need maximum throughput.
How do you use two internet connections at once with Starlink?
Speedify combines Starlink with any other connection — cellular, cable, Wi-Fi, or a second dish — into one bonded connection. Speedify runs on your phone, laptop, or router. When Starlink drops, Speedify moves your traffic to the backup instantly, so calls don’t cut out and downloads don’t stall. Speedify is free to try.
71% of Speedify’s Starlink users already run a second connection. The data below shows why.

Starlink goes down every day.
Here’s what that actually looks like.
Speedify passively monitors every connection it bonds. These figures come from 6,209 Starlink users over 14 days — compared in real time against the other connections on the same devices. No speed tests, no lab conditions.
Daily downtime

71% ran at least one other connection simultaneously — 4,381 of 6,209 users. Cellular is the most common backup.
How Speedify Bonds Starlink as a Supported Product
Speedify connects to Speedify’s global server network and splits traffic at the packet level across every available connection at once – Starlink, Wi-Fi, 4G/5G cellular, wired Ethernet, other satellite. A single transfer, call, or stream uses the combined capacity of all bonded links, up to 95% of theoretical aggregate throughput, with failover to the remaining connections in under a second.
OpenMPTCProuter requires a supported OpenWrt router on site and a separate VPS that the business installs, secures, and maintains as the aggregation endpoint. It depends on Multipath TCP, which works well for TCP throughput but is weaker for real-time and UDP traffic over cellular, and connections need latency under 500 ms to participate. There is no commercial support contract behind it.
Speedify runs on Windows, Mac, Linux, iOS, Android, and supported OpenWrt routers with no VPS to build, and handles real-time traffic such as VoIP and video calls alongside bulk transfer. Speedify has run in production since 2014 across 15 million downloads.
Speedify also gives a business something OpenMPTCProuter users explicitly lose once their dish is bonded behind the tunnel: visibility into the Starlink dish itself. Speedify’s Starlink Control Center reads obstruction maps, throughput, ping, uptime, and dish alerts from each dish, with alignment tools for multi-dish aiming. Speedify’s cellular sharing feature pools 4G/5G cellular across devices on the same network.

Which Speedify Deployment Suits an OpenMPTCProuter Evaluation
Teams that reach for OpenMPTCProuter usually want bonding on a router without a per-device client. The Speedify deployment that matches is a Powered by Speedify router on OpenWrt, GL.iNet, or Miri hardware, which bonds the whole network without a VPS to stand up.
Businesses that want their own controlled endpoint can add Speedify Self-Hosted Servers to any plan, which delivers the self-hosted control of a VPS endpoint as a supported component rather than a maintenance task. See the supported routers list.
