Compare Gaffa vs. Jaunt

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.

Jaunt is a Java library tailored for web scraping, web automation, and querying JSON data. It features a lightweight, fast headless browser that allows Java applications to execute web scraping, manage forms, and interact with RESTful APIs. This library can parse various formats such as HTML, XHTML, XML, and JSON, while also providing functionalities like manipulation of HTTP headers and cookies, support for proxies, and options for customizable caching. Although Jaunt does not execute JavaScript, users looking to automate JavaScript-capable browsers are encouraged to use Jauntium. Distributed under the Apache License, Jaunt has a monthly version that requires periodic updates, compelling users to download the latest release once it expires. It is particularly effective for tasks that involve extracting and parsing data from web pages, submitting filled forms, and managing HTTP requests and responses. Additionally, users can find extensive tutorials and documentation to help them efficiently navigate and utilize the features of Jaunt, making it an accessible choice for developers.
