Gaffa
Gaffa is a REST API built for web scraping and browser automation, allowing developers to run real, full browsers at scale with a single API call. It removes the difficulty of managing headless browser frameworks, rotating proxies, CAPTCHA solving, and scaling infrastructure, all of which are handled automatically. JavaScript-heavy and dynamic websites render exactly as they would for a human visitor by default. Beyond standard scraping, Gaffa supports AI-driven structured data extraction (extract data into a defined schema without writing CSS selectors), screenshot and PDF capture, infinite-scroll and form-filling automation, and clean Markdown conversion for feeding webpages directly into LLM and RAG pipelines. A rotating residential proxy network keeps access reliable across regions, and a credit-based pricing model means teams pay only for the browser time and bandwidth they actually use. Gaffa is designed for AI engineers, data teams, and developers who want production-grade web data extraction without having to build and maintain their own infrastructure.

Description

HtmlUnit serves as a "GUI-less browser for Java applications," designed to model HTML documents while providing an API for interactions with web pages, such as loading pages, submitting forms, and following links, which mirrors the functionality of a traditional web browser. Its JavaScript support is notably robust and continues to evolve, allowing it to effectively manage complex AJAX scenarios, and it can mimic various browsers like Chrome, Firefox, or Edge based on the chosen settings. While primarily aimed at testing or data extraction from websites, HtmlUnit is not a standalone unit testing framework; instead, it functions within larger testing frameworks like JUnit or TestNG to replicate browser behavior. This tool serves as the foundation for many open-source applications, including WebDriver, Arquillian Drone, and Serenity BDD, and is widely adopted by numerous projects focused on automated web testing, such as Apache Shiro, Apache Struts, and Quarkus. Its ability to operate without a graphical user interface makes it particularly valuable for developers seeking to automate browser interactions in a more efficient and resource-friendly manner.

Description

Inspect Element is a native feature found in most web browsers that enables users to examine and modify a website's HTML, CSS, and JavaScript code in real time. This capability is especially beneficial for web developers, designers, and digital marketers, as it allows them to debug elements, test layout modifications, and engage in live CSS editing. The tool presents the HTML structure of the webpage, enabling users to select and investigate specific components. The corresponding CSS styles are displayed in a separate panel, where users can make temporary changes to observe how those alterations impact the page's visual presentation. Importantly, these modifications are local and do not affect the actual website; if the page is refreshed, it returns to its original state. This feature is crucial for experimenting with design adjustments, resolving issues, and understanding how various web elements are assembled. Additionally, our platform emphasizes adaptability, recognizing that every production site globally is distinctive, just like the solutions we provide. In this way, we ensure that our tools cater to the diverse needs of our users.
