Best Browser Automation Tools for JavaScript

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.

Web Scraping API and Proxy Server ZenRows API manages rotating proxy, headless browsers, and CAPTCHAs. With a simple API call, you can easily collect content from any website. ZenRows can bypass any anti-bot blocking system to help get the information you need. We offer several options, such as Javascript rendering or Premium proxy. The autoparse option will automatically return structured data. It will convert unstructured data into structured data (JSON output) without the need for code. ZenRows provides high accuracy and success rates without the need for human intervention. It will take care of all the details. Premium Proxies are required for domains that are particularly complex (e.g. Instagram). The success rate for all domains will be equal after they are enabled. If the request returns an error, it will not be charged nor computed. Only successful requests will be counted.
