Quora users ask how fast Speedify really is
Quick answer
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.

Best for fixed locations. Different network, so outages rarely overlap.
Learn more →Second Starlink
Adds redundancy and throughput for remote sites or heavy usage.

Speedify gives you faster, steadier internet by combining Wi-Fi, cellular, and Starlink
Speedify bonds Wi-Fi, 4G/5G cellular, Ethernet, and Starlink into one connection at the same time, giving you more speed, automatic failover when one drops, and AES-256 encryption on every link.
Download Speedify ›More speed
Upload and download speeds combine across every active connection on your device.
Automatic failover
If a connection drops, Speedify moves your traffic to another in milliseconds. Calls stay connected.
Always encrypted
Every link runs through an encrypted tunnel, including public Wi-Fi, cellular, and Starlink.
Speedify Feature · Pair & Share
Speedify Pair & Share: share cellular between your devices, both ways
Most hotspots give. Speedify's Pair & Share gives and takes. Two devices running Speedify pair up and each uses the other's cellular connection simultaneously, so you both get faster uploads, faster downloads, and a steadier connection. No extra hardware, no new data plans, no setup beyond a tap.
Learn how Speedify's Pair & Share works ›More speed
Every device you pair with adds its cellular to yours, and yours to theirs.
Stays connected
If a paired device drops out, Speedify keeps you online on the remaining links.
Always private
Every shared connection runs through AES-256 encryption. Your traffic is yours.
No new gear
Runs on devices already running Speedify, over your local network. Pair once, reconnects automatically.
96% Bonding Efficiency for Speedify
At the highest level, Speedify does two big things to help speed up your Internet:
- It lets you combine the bandwidth of multiple Internet connections
- It detects and re-sends lost packets
- It does all this with a VPN twist, encrypting your online traffic to protect your privacy and sensitive data
So, I set up two identical 3 Mbps Internet links, with 50 ms round trip time as latency, and then slowly dialed up the loss.
I tested with 3 software setups:
- 1 Connection, No Speedify – Just TCP on the Internet.
- 1 Connection with Speedify – Speedify running on a single Internet link
- 2 Connections with Speedify – Speedify running, allowed to use both Internet links.
The results were as follows:
A couple observations:
- Speedify added about 3% overhead to the single link, making it .1Mbps slower when there was no loss.
- But as the loss increases, the “No Speedify” throughput collapses. At 5% loss the throughput is down to about 25% of full speed. (And this can be a real scenario with WiFi, by the way)
- Speedify offers great protection from this loss. At 5% loss, it’s 234% the speed of TCP without Speedify
- Bonding Works! Even with no loss, the Speedify 2 Connection speed is 193% the speed of just TCP on one link (96%) bonding efficiency. This is especially critical in bandwidth intensive applications like Twitch gaming, video streaming, etc.
Your mileage may vary, in particular:
- Speedify does adjust to non-identical Internet links to allow them to be bonded. But as the latencies and speeds get further apart, the bonding efficiency does come down.
- How badly TCP is affected by loss is affected by latency. At higher latencies, Speedify can end out doubling your performance at just 1% loss.
- We were then focused on combined speeds of up to 50 Mbps, this was not (yet) a service for Google Fiber users.
- I didn’t talk about Redundant Mode at all… usually lower throughput but delivers very consistent, non-jittery performance (lower average ping times).
