hardkoded/puppeteer-sharp: Headless Chrome .NET API

Puppeteer Sharp is a .NET port of the official Node.JS Puppeteer API.

PuppeteerSharp now supports AOT compilation! Check the PuppeteerSharp 19 release notes!.

• API Documentation
• Slack channel #puppeteer-sharp
• StackOverflow
• Issues
• Blog

• Puppeteer-Sharp comes in two flavors: a NetStandard 2.0 library for .NET Framework 4.6.1 and .NET Core 2.0 or greater and a .NET 8 version.
• If you have issues running Chrome on Linux, the Puppeteer repo has a great troubleshooting guide.
• X-server is required on Linux.

Some of the best ways to contribute are to try things out file bugs and fix issues.

If you have an issue or a question:

• Ask a question on Stack Overflow.
• File a new issue.

See this document for information on how to contribute.

var browserFetcher = new BrowserFetcher();
await browserFetcher.DownloadAsync();
await using var browser = await Puppeteer.LaunchAsync(
    new LaunchOptions { Headless = true });
await using var page = await browser.NewPageAsync();
await page.GoToAsync("http://www.google.com");
await page.ScreenshotAsync(outputFile);

You can also change the view port before generating the screenshot

await Page.SetViewportAsync(new ViewPortOptions
{
    Width = 500,
    Height = 500
});

^{snippet source | anchor}

var browserFetcher = new BrowserFetcher();
await browserFetcher.DownloadAsync();
await using var browser = await Puppeteer.LaunchAsync(new LaunchOptions { Headless = true });
await using var page = await browser.NewPageAsync();
await page.GoToAsync("http://www.google.com"); // In case of fonts being loaded from a CDN, use WaitUntilNavigation.Networkidle0 as a second param.
await page.EvaluateExpressionHandleAsync("document.fonts.ready"); // Wait for fonts to be loaded. Omitting this might result in no text rendered in pdf.
await page.PdfAsync(outputFile);

await using var page = await browser.NewPageAsync();

    using (var page = await browser.NewPageAsync())
    {
        await page.GoToAsync(url);
        await page.PdfAsync("wot.pdf");
