libzt

Embed ZeroTier directly into your app

---

ZeroTier makes it easy to securely connect devices, servers, cloud VMs, containers, and apps everywhere and manage them at scale. Now, with libzt you can bake this ability directly into your app or service using your preferred language or framework. We provide a BSD socket-like API to make the integration simple.

Example

#include "libzt.h"

char *str = "welcome to the machine";
char *nwid = "c7cd7c9e1b0f52a2";

zts_simple_start("./zt", nwid);
if((fd = zts_socket(AF_INET, SOCK_STREAM, 0)) < 0) {
	printf("error creating ZeroTier socket");
}
if((err = zts_connect(fd, (const struct sockaddr *)addr, sizeof(addr))) < 0) {
	printf("error (%d) connecting to remote host\n", err);
}
int wrote = zts_write(fd, str, strlen(str));
zts_close(fd);

Bindings also exist for many popular languages and platforms.
