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• wkhtmltopdf - outdated rendering engine, CSS issues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:

• HTML/URL to PDF (uses real Chrome via PuppeteerSharp)
• Full CSS3 support (flexbox, grid, media queries)
• Browser pool for concurrent requests
• PDF operations (merge, split, watermark, encrypt)
• ASP.NET Core integration with this.Pdf() extension

What it doesn't do:

• No magic - still needs Chromium
• Not for pixel-perfect reports from scratch

GitHub: Flavor
NuGet: dotnet add package Flavor

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