## What it is
UDPspeeder is a C++ tunnel tool that improves network quality over high-latency, lossy links using Forward Error Correction (Reed-Solomon codes). Used alone it accelerates UDP traffic; combined with a UDP-based VPN such as OpenVPN it can improve all traffic including TCP and ICMP.

## Use cases
- reduce packet loss on a lossy network link
- improve scp/ssh speed over high-latency connections
- tunnel UDP traffic with forward error correction
- make OpenVPN more reliable over a lossy link
- lower ping packet loss between two servers
- speed up single-thread TCP downloads on bad connections

## When to choose
- you have a high-latency, lossy link (e.g., cross-border or satellite) and can spare extra bandwidth
- you want to pair FEC with a UDP-based VPN to fix all traffic types
- you run Linux, OpenWRT, Raspberry Pi, or Android and need a lightweight CLI tool

## When to avoid
- your link is already reliable and bandwidth-constrained, since FEC trades bandwidth for reliability
- you need a native Windows or macOS binary without a virtual machine
- you want a full VPN solution rather than a tunnel accelerator
