Open Source JavaScript Headless Browsers for Windows

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.

Playwright is a Node library for automating Chromium, Firefox and WebKit using a single API. It supports headless execution for all these browsers on Linux, macOS and Windows, providing automated web browser interactions that are fast, capable, reliable and ever-green. Playwright enables a broad spectrum of cross-browser web automation capabilities, which are used by Single Page Apps and Progressive Web Apps. These include scenarios that span multiple pages, domains and iframes; emulation of mobile devices, geolocation, and permissions; upload and download files and many more.

Puppeteer is a headless Node library that provides a high level API for controlling Chromium or Chrome over the DevTools protocol. It requires zero setup and comes bundled with the Chromium version most suited to it. Puppeteer is headless by default, making it fast to run. However, it can also be set to run full or non-headless Chrome or Chromium, simply set the headless option when launching a browser. Many of the things you can do manually in the browser, you can also do with Puppeteer such as generate page screenshots and PDFs, crawl a Single-Page Application, test Chrome extensions and more.

The zeta.js library provides the facilities to run an instance of ZetaOffice integrated into your web site, allowing you to control it with JavaScript code via the LibreOffice UNO technology. Use cases range from an in-browser office suite that looks and feels just like its desktop counterpart, to fine-tuned custom text editing and spreadsheet capabilities embedded in your website, to a headless zetajs instance that does document conversion in the background.

Playwright for .NET is the official language port of Playwright, the library to automate Chromium, Firefox and WebKit with a single API. Playwright is built to enable cross-browser web automation that is ever-green, capable, reliable and fast. Cross-browser. Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Cross-platform. Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Cross-language. Use the Playwright API in TypeScript, JavaScript, Python, .NET, Java. Test Mobile Web. Native mobile emulation of Google Chrome for Android and Mobile Safari. The same rendering engine works on your Desktop and in the Cloud. Auto-wait. 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.

Visual regression testing for web apps. Supports screen rendering with Chrome-headless. Add your own interactions with the Playwright and Puppeteer scripting. BackstopJS automates visual regression testing of your responsive web UI by comparing DOM screenshots over time.

It's a little different from other options because it doesn't use a headless browser to render content. This tradeoff allows Critters to be very fast and lightweight. It also means Critters inlines all CSS rules used by your document, rather than only those needed for above-the-fold content. Critters' design makes it a good fit when inlining critical CSS for prerendered/SSR'd Single Page Applications. It was developed to be an excellent compliment to the prerender-loader, combining to dramatically improve first paint time for most Single Page Applications. Import Critters into your Webpack configuration and add it to your list of plugins. That's it! Now when you run Webpack, the CSS used by your HTML will be inlined and the imports for your full CSS will be converted to load asynchronously. Create a Critters plugin instance with the given options.

Differencify is a library for visual regression testing via comparing your local changes with reference screenshots of your website. It is built on top of chrome headless using Puppeteer.

A web interface to IPFS, shipped with Kubo, and ipfs-desktop. Check on your node stats, explore the IPLD powered merkle forest, see peers around the world and manage your files, without needing to touch the CLI. When working on the code, run an ipfs daemon, the local dev server, the unit tests, and the storybook component viewer and see the results of your changes as you save files. If you need to run IPFS in a Docker container, you can still have Web UI available by exposing both the Gateway and Web UI ports. The end-to-end tests (E2E) test the full app in a headless Chromium browser. They spawn real IPFS node for HTTP API and a static HTTP server to serve the app. The purpose of those tests is not being comprehensible, but act as a quick regression and integration suite.

A visual regression testing library/tool, aims to quickly automate browser-based tests with minimum development overhead. To test flexibly in different testing scenarios, either testing against web UI wired with backends or just static web pages, VBot exposes API to be used with testing frameworks like mocha or ava, etc. Therefore, the test data variables can be updated according to different conditions, in order to decouple from real backends and avoid false negative results.

Insanely fast, headless full-stack testing using Node.js. Zombie 6.x is tested to work with Node 8 or later. If you need to use Node 6, consider using Zombie 5.x. If you’re going to write an insanely fast, headless browser, how can you not call it Zombie? Zombie it is. Zombie.js is a lightweight framework for testing client-side JavaScript code in a simulated environment. No browser required. Zombie will work with other testing frameworks. Since Mocha supports promises. Just like your favorite Web browser, Zombie manages multiple open windows as tabs. New browsers start without any open tabs. As you visit the first page, Zombie will open a tab for it. All operations against the browser object operate on the currently active tab (window) and most of the time you only need to interact with that one tab. You can access it directly via browser.window. You can access all open tabs from browser.tabs. This property is an associative array, you can access each tab by its index number.
