Libraries

Every part of VpnHood is a set of packages on NuGet. Pick a group: its page says what it is for, when to use it, and which package to take.

Networking

Standalone .NET libraries for the network layer a VPN is built on. None of them needs a VPN: each one works in any .NET application.

VPN adaptersA virtual network interface on Windows, Linux, Android and iOS, behind one API.7 packages

PacketsRead and build IPv4 and IPv6 packets, with their TCP, UDP and ICMP parts.1 package

Packet transportsTwo-way channels of IP packets, with send queues, batching and a fair queue.1 package

TCP stackTurn the TCP connections inside raw packets into .NET streams.2 packages

QUICOne small QUIC API, with MsQuic, Android and iOS underneath.4 packages

ProxiesSOCKS5, SOCKS4 and HTTP(S) proxy clients and servers.1 package

IP locationsFind the country of an IP address, online or from a local database.2 packages

VPN Core

The VPN itself: the client and server engines, the tunnel between them, and the parts that decide where traffic goes and who may connect.

AbstractionWhat the engine's parts agree on, with no engine inside.1 package

ClientThe client engine, the VPN service that runs it, each platform's device, and their contracts.16 packages

ServerRun a VpnHood server, with its access keys in files or in the MANAGER.3 packages

TunnelingThe tunnel a client and a server share.1 package

FilteringDecide which traffic goes through the tunnel: by IP range, country or domain.3 packages

Proxy managementPut the client's tunnel inside a proxy: one proxy, or a managed list that rates and rotates them.3 packages

App Logic

Everything a VPN app does below its screens, the same on every platform. Your app adds the screens and a head for each platform, as the template does.

AbstractionWhat a head plugs into the app - accounts, billing, ads, updates - as interfaces.1 package

AppA whole VPN app without its screens, on every platform.6 packages

APIThe app's API for any UI, in the same process or over HTTP.3 packages

StoresBilling, sign-in, updates and reviews through Google Play, the App Store and the Microsoft Store.6 packages

AdsAdMob's app-open, interstitial and rewarded ads, with Google's consent form.1 package

PortalAccounts, sign-in and web purchases through the VpnHood Portal.1 package

App UI

The app's screens and the hosts that run them, from a phone to a desktop service.

AbstractionThe app as any UI toolkit sees it: its state, its words and their text.1 package

HostingRun a UI for the app - Avalonia, a web view or MAUI - on a phone, a desktop or in a browser.16 packages
