    Algo VPN

    Algo VPN

    Set of Ansible scripts that simplifies the setup of a personal VPN

    Introducing Algo, a self-hosted personal VPN server designed for ease of deployment and security. Algo automatically deploys an on-demand VPN service in the cloud that is not shared with other users, relies on only modern protocols and ciphers, and includes only the minimal software you need. And it’s free. For anyone who is privacy conscious, travels for work frequently, or can’t afford a dedicated IT department, this one’s for you. Really, the paid-for services are just commercial honeypots. If an attacker can compromise a VPN provider, they can monitor a whole lot of sensitive data. Paid-for VPNs tend to be insecure: they share keys, their weak cryptography gives a false sense of security, and they require you to trust their operators. Even if you’re not doing anything wrong, you could be sharing the same endpoint with someone who is. In that case, your network traffic will be analyzed when law enforcement makes that seizure.

    Udp2raw-tunnel

    Udp2raw-tunnel

    Turns UDP traffic into encrypted UDP/fakeTCP/ICMP traffic

    A tunnel which turns UDP traffic into encrypted fakeTCP/UDP/ICMP traffic by using Raw Socket, helps you bypass UDP FireWalls(or unstable UDP environment). When used alone, Udp2raw tunnels only UDP traffic. Nevertheless, if you used udp2raw + any UDP-based VPN together, you can tunnel any traffic(include TCP/UDP/ICMP), currently, OpenVPN/L2TP/ShadowVPN and tinyfecVPN are confirmed to be supported. Linux host (including desktop Linux,Android phone/tablet,OpenWRT router,or Raspberry PI) with root account or cap_net_raw capability. ICMP/FakeTCP headers help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. In ICMP header mode,udp2raw works like an ICMP tunnel. UDP headers are also supported. In UDP header mode, it behaves just like a normal UDP tunnel, and you can just make use of the other features (such as encryption, anti-replay, or connection stalization).

    Outline Server

    Outline Server

    Outline Manager, developed by Jigsaw

    Access to the free and open Internet. Outline makes it easy to create a VPN server, giving anyone access to the free and open Internet. Outline allows anyone to access the free and open Internet more securely by running their own VPN. Running your own VPN server with Outline increases the security of Internet access and makes the connection harder to block. VPNs are useful to protect the privacy of your communications and allow you to keep access to the Internet open.

Outline allows anyone to create their own VPN, run it, and share access to it. Outline is designed to offer block resistance. It allows you to control your server settings, including its location. Furthermore, Outline is a 100% open-source project that uses transparent technology and has undergone audits by two security companies.
