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

Browserless is a cloud-based web scraping and browser automation platform built to help developers access, extract, and automate data collection from websites protected by advanced bot detection systems. The platform uses BrowserQL and Chrome DevTools Protocol-level browser control to bypass anti-bot protections such as Cloudflare, Datadome, and other detection technologies commonly used to block automated traffic. Browserless supports multiple scraping workflows including HTML extraction, JSON output generation, screenshot capture, browser rendering, and complex browser automation using standard Puppeteer and Playwright libraries. Developers can use the platform to navigate dynamic websites, interact with page elements, execute scripts, click buttons, and automate browser-based workflows without managing their own headless browser infrastructure. Session reconnect functionality allows users to preserve cookies, session data, and browser states, reducing repeated page loads and lowering proxy usage during large-scale scraping operations. Browserless also offers WebSocket endpoints that integrate directly with automation tools and frameworks for greater workflow flexibility and customization. The platform’s optimized infrastructure delivers faster scraping performance compared to self-managed browser environments while simplifying deployment and maintenance. Security and compliance features including SOC 2 Type II certification, GDPR compliance, HIPAA compliance, and available DPAs help organizations maintain secure and compliant data operations.
