Proton VPN Browser Extension
Proton VPN Browser Extension
The Proton VPN Browser Extension repository houses the code for an official browser extension that lets users quickly secure their web browsing traffic through ProtonVPN from within browsers like Firefox and Chrome without routing all system traffic. This extension provides users with a convenient way to encrypt and anonymize HTTP requests, hide IP addresses, and prevent tracking while browsing, acting independently of the full OS-level VPN clients. Because browser extensions are constrained by browser APIs, this extension focuses on securing in-browser connections, protecting privacy specifically within the browser context rather than across the entire operating system. Users can sign in with their Proton accounts, choose from available VPN locations, and connect or disconnect from the toolbar with a single click, making it practical for casual privacy protection or geo-unblocking content without installing native applications. -

Tailscale is an open-source zero-configuration VPN and networking solution that makes it simple to create secure, private networks across devices by leveraging WireGuard under the hood. It lets users connect computers, servers, mobile devices, and cloud instances together with peer-to-peer encrypted tunnels without dealing with complex firewalls, NAT rules, or key distribution headaches. Instead of traditional VPN server infrastructure, Tailscale uses a coordination service to authenticate devices and exchange connection information, enabling automatic NAT traversal and minimal manual setup. The project includes a daemon (tailscaled) and a CLI tool that run on major operating systems, and it also forms the basis for the official clients on platforms like iOS and Android, though those have GUI wrappers not fully in this repository. -

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). -

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. -
