I built a free HTML to PDF library for .NET because existing options frustrated me

Hey everyone,

I'm a .NET developer and I needed a simple way to convert HTML to PDF. Looked at existing options:

Paid libraries - expensive licenses for a basic feature
PuppeteerSharp directly - works, but lots of boilerplate (browser lifecycle, resource cleanup, pooling)
wkhtmltopdf - outdated rendering engine, CSS issues

So I built Flavor - a free, open source wrapper that handles the boring parts.

var pdf = await new FlavorConverter().ConvertHtmlAsync("<h1>Hello</h1>");

What it does:

What it doesn't do:

GitHub: Flavor
NuGet: dotnet add package Flavor

Looking for feedback. What's missing? What would make you actually use this?
