    Selenium

    Selenium

    Browser automation framework and ecosystem

    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.

    FlareSolverr

    FlareSolverr

    Proxy server to bypass Cloudflare protection

    FlareSolverr is a proxy server to bypass Cloudflare and DDoS-GUARD protection. FlareSolverr starts a proxy server, and it waits for user requests in an idle state using few resources. When some request arrives, it uses puppeteer with the stealth plugin to create a headless browser (Firefox). It opens the URL with user parameters and waits until the Cloudflare challenge is solved (or timeout). The HTML code and the cookies are sent back to the user, and those cookies can be used to bypass Cloudflare using other HTTP clients. Web browsers consume a lot of memory. If you are running FlareSolverr on a machine with few RAM, do not make many requests at once. With each request, a new browser is launched. It is also possible to use a permanent session. However, if you use sessions, you should make sure to close them as soon as you are done using them. It is recommended to install using a Docker container because the project depends on an external browser that is already included.

    Lightpanda Browser

    Lightpanda Browser

    Lightpanda: the headless browser designed for AI and automation

    Lightpanda is an open-source headless browser designed specifically for automation, artificial intelligence workflows, and large-scale web interaction tasks. Unlike traditional browsers that include full graphical rendering engines meant for human users, Lightpanda is built from scratch to operate entirely in headless mode, focusing only on the components required for programmatic web interaction. This design allows it to execute JavaScript and interact with web pages while avoiding the overhead associated with rendering images, fonts, and layout elements intended for visual display. The browser is implemented using the Zig programming language and integrates the V8 JavaScript engine to run modern web applications and scripts efficiently. Because it avoids graphical rendering and other heavy browser components, the system uses significantly less memory and launches almost instantly compared to conventional browsers such as Chrome.

    crawlee

    crawlee

    A web scraping and browser automation library for Node.js

    Crawlee is a web scraping and browser automation library. It helps you build reliable crawlers. Fast. Crawlee won't fix broken selectors for you (yet), but it helps you build and maintain your crawlers faster. When a website adds JavaScript rendering, you don't have to rewrite everything, only switch to one of the browser crawlers. When you later find a great API to speed up your crawls, flip the switch back. It keeps your proxies healthy by rotating them smartly with good fingerprints that make your crawlers look human-like. It's not unblockable, but it will save you money in the long run. Crawlee is built by people who scrape for a living and use it every day to scrape millions of pages. Meet our community on Discord. We believe websites are best scraped in the language they're written in. Crawlee runs on Node.js and it's built in TypeScript to improve code completion in your IDE, even if you don't use TypeScript yourself.

    Critters

    Critters

    A Webpack plugin to inline your critical CSS and lazy-load the rest

    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.
