Official SDKs & tools

.NET — C# & VB.NET

The PWFAuth package on NuGet covers both C# and VB.NET, WinForms to console. It targets netstandard2.0 + net8.0, so it works from .NET Framework 4.6.2 up to modern .NET. Async API, a SessionEnded event for the kill switch, and heartbeat management handled for you.

dotnet add package PWFAuth

Node.js

The pwfauth package on npm — Node 18+, pure ESM, zero dependencies, TypeScript types included. A promise-based client with a sessionEnded event, for Electron apps, CLI tools, and license-gated servers.

npm install pwfauth

Python

The pwfauth package on PyPI — Python 3.9+, synchronous client with a background heartbeat thread and an on_session_ended callback. One dependency (cryptography, installed automatically); HTTP uses the standard library.

pip install pwfauth

VS Code extension

The PWF Auth extension brings integration snippets into your editor. Install it from the Extensions panel or:

code --install-extension PWFAuth.pwfauth

SDK Generator — any other language

Working in C++, Java, Dart, PHP, or something else? The dashboard's SDK Generator writes a ready-to-paste client for your language, already wired to your app's ID and secret — envelope crypto, heartbeat, and kill-switch handling included. You'll find it in the dashboard sidebar after creating a free account.

And because every SDK is just a client for the same documented HTTP API, anything that can make an HTTPS request can integrate — the API reference specifies the raw contract, including the signed envelope.
