What are Headless Browsers for C#?

A headless browser is a web browser that operates without a graphical user interface (GUI), allowing tasks to be performed programmatically instead of through direct user interaction. It processes web pages, including rendering and executing JavaScript, just like a standard browser but works entirely in the background. This makes it a valuable tool for tasks such as web scraping, automated testing, and performance analysis. By running without a visual interface, headless browsers are faster and more resource-efficient than traditional browsers. They are widely used in automation workflows to interact with and analyze web content seamlessly.

ZenRows

ZenRows

Web Scraping API & Proxy Server ZenRows API handles rotating proxies, headless browsers and CAPTCHAs for you. Easily collect content from any website with a simple API call. ZenRows will bypass any anti-bot or blocking system to help you obtain the info you are looking for. For that, we include several options such as Javascript Rendering or Premium Proxies. There is also the autoparse option that will return structured data automatically. It will convert unstructured content into structured data (JSON output), with no code necessary. ZenRows offers a high accuracy and success rate without any human intervention. No more CAPTCHAs or setting up proxies; it will be handled for you. Some domains are especially complicated (i.e., Instagram), and for those, Premium Proxies are usually required. After enabling them, the success rate will be equally high. In case the request returns an error, we will not compute nor charge that request. Only successful requests will count.

Selenium

Software Freedom Conservancy

Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point.

Puppeteer

Puppeteer

Most things that you can do manually in the browser can be done using Puppeteer! Puppeteer-core is intended to be a lightweight version of Puppeteer for launching an existing browser installation or for connecting to a remote one. Be sure that the version of puppeteer-core you install is compatible with the browser you intend to connect to. Puppeteer will be familiar to people using other browser testing frameworks. You create an instance of Browser, open pages, and then manipulate them with Puppeteer's API. By default, Puppeteer downloads and uses a specific version of Chromium so its API is guaranteed to work out of the box. To use Puppeteer with a different version of Chrome or Chromium, pass in the executable's path when creating a Browser instance.

Playwright

Playwright

Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met. Configure test retry strategy, capture execution trace, videos, screenshots to eliminate flakes. Browsers run web content belonging to different origins in different processes. Playwright is aligned with the modern browsers architecture and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.
