Open Source JavaScript Web Scrapers

The UI Vision RPA software is the tool for visual process automation, codeless UI test automation, web scraping and screen scraping. Automate tasks on Windows, Mac and Linux. The UI Vision RPA core is open-source with enterprise security. The free and open-source browser extension can be extended with local apps for desktop UI automation. UI.Vision RPA's computer-vision visual UI testing commands allow you to write automated visual tests with UI.Vision RPA - this makes UI.Vision RPA the first and only Chrome and Firefox extension (and Selenium IDE) that has "👁👁 eyes". A huge benefit of doing visual tests is that you are not just checking one element or two elements at a time, you’re checking a whole section or page in one visual assertion. The visual UI testing and browser automation commands of UI.Vision RPA help web designers and developers to verify and validate the layout of websites and canvas elements.

A visual code-free/no-code web crawler/spider, supporting both Chinese and English.

Remote isolated browser API for security, automation visibility and interactivity. Run-on our cloud, or bring your own. Full scope double reverse web proxy with a multi-tab, mobile-ready browser UI frontend. Plus co-browsing, advanced adaptive streaming, secure document viewing and more! But only in the Pro version. BrowserBox is a full-stack component for a web browser that runs on a remote server, with a UI you can embed on the web. BrowserBox lets your provide controllable access to web resources in a way that's both more sandboxed than, and less restricted than, traditional web <iframe> elements. Build applications that need cross-origin access, while delivering complex user stories that benefit from an encapsulated browser abstraction. Since the whole stack is written in JavaScript you can easily extend it to suit your needs. The technology that puts unrestricted browser capabilities within reach of a web app has never before existed in the open.

A simple (and unofficial) GitHub Trending client that lives in your menubar. Raise is a simple extension for GitHub Trending you can use to browse trending repositories and developers at any time. Raise is an open-source project so if you have any problems, feel free to submit an issue on GitHub! Raise is developed on Node.js v16. Other Node.js versions have not been tested.

Supports strings, arrays, arrays of objects, and nested object structures. The schema is not tied to the structure of the page you're scraping, allowing you to pull the data in the structure of your choosing. The API is entirely composable, giving you great flexibility in how you scrape each page. Paginate through websites, scraping each page. X-ray also supports a request delay and a pagination limit. Scraped pages can be streamed to a file, so if there's an error on one page, you won't lose what you've already scraped. Start on one page and move to the next easily. The flow is predictable, following a breadth-first crawl through each of the pages. X-ray has support for concurrency, throttles, delays, timeouts and limits to help you scrape any page responsibly. Swap in different scrapers depending on your needs. Currently supports HTTP and PhantomJS driver drivers. In the future, I'd like to see a Tor driver for requesting pages through the Tor network.

The aim of this library is to be a comprehensive source for extracting all HTML-embedded metadata. Currently, it supports Schema.org microdata using a third-party library, a native BEPress, Dublin Core, Highwire Press, JSON-LD, Open Graph, Twitter, EPrints, PRISM, and COinS implementation, and some general metadata that doesn't belong to a particular standard (for instance, the content of the title tag, or meta description tags). Planned is support for RDFa, AGLS, and other yet unheard-of metadata types. Contributions and requests for other metadata types are welcome! You can also pass an options object as the first argument containing extra parameters. Some websites require the user-agent or cookies to be set in order to get the response.

OpenWebSpider is an Open Source multi-threaded Web Spider (robot, crawler) and search engine with a lot of interesting features!

I'm a fan of Python library BeautifulSoup. It's feature-rich and very easy to use. But when I am working on a small react-native project, and I tried to find a HTML parser library like BeautifulSoup, I failed. So I want to write a HTML parser library that can be so easy to use just like BeautifulSoup in Javascript. JSSoup uses tautologistics/node-htmlparser as HTML dom parser, and creates a series of BeautifulSoup like API on top of it. JSSoup supports both node and react-native. JSSoup tries to use the same interfaces as BeautifulSoup so BeautifulSoup user can use JSSoup seamlessly. However, JSSoup uses Javascript's camelCase naming style instead of Python's underscore naming style.

ScrapBot is a task automation software that allows you to access, authenticate, extract, and insert data on any website. The software utilizes JavaScript to execute tasks, eliminating the need for server or additional software installations. The system can control the accessed webpage through JavaScript, and the entire navigation can be viewed in the program window. The main.js script runs in a separate frame from the navigation frame but can access all page content without any restrictions.

Spider is web crawler written in the Java.Based on an Regular expression string the spider parses the internet for web pages matching this string and stores it in an MYSQL database.

PHP web API designed to simplify object handling(loading, saving, querying, displaying, and editing), abstract the data from its display structure, and layout and allow the target data to be delivered to any supported format without special logic.

Serverless Chrome contains everything you need to get started running headless Chrome on AWS Lambda (possibly Azure and GCP Functions soon). The aim of this project is to provide the scaffolding for using Headless Chrome during a serverless function invocation. Serverless Chrome takes care of building and bundling the Chrome binaries and making sure Chrome is running when your serverless function executes. In addition, this project also provides a few example services for common patterns (e.g. taking a screenshot of a page, printing to PDF, some scraping, etc.). Why? Because it's neat. It also opens up interesting possibilities for using the Chrome DevTools Protocol (and tools like Chromeless or Puppeteer) in serverless architectures and doing testing/CI, web-scraping, pre-rendering, etc. You must configure your AWS credentials either by defining AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environmental variables, or using an AWS profile.

studiMaps is a web based application for visualization and analysis of social networks. It consists of two software components: a web-crawler for getting data and the web based application for visualization.
