MiniUPnP is a lightweight ANSI C implementation of the UPnP Internet Gateway Device (IGD) specifications, comprising a client library (miniupnpc), a gateway daemon (miniupnpd) with NAT-PMP/PCP support, and an SSDP daemon (minissdpd). It is designed for a minimal footprint with no external dependencies, making it suitable for embedded and low-memory devices.

Use cases

• open a port on a router programmatically via UPnP
• add NAT traversal to a peer-to-peer application
• run a UPnP IGD gateway daemon on a Linux router
• discover UPnP gateways on the local network with SSDP
• forward ports for a game server or self-hosted service automatically
• implement NAT-PMP or PCP client support in C

When to choose

• you need a tiny, dependency-free C library for UPnP IGD or NAT-PMP/PCP
• you run a router or gateway on Linux/BSD and want to expose UPnP port mapping
• you target embedded or low-memory devices
• you need portable NAT traversal across POSIX systems and Windows

When to avoid

• you need DLNA media server or renderer functionality rather than IGD
• you want a high-level UPnP stack with XML parsing and rich service discovery
• your project is not in C or lacks C bindings
• you need modern protocol alternatives like NAT hole punching via WebRTC
