Zenrows was founded in 2021 with the goal to turn any website into an API.
ZenRows is a web scraping API, a tool used for data extraction that comes with rotating proxies, headless browser functionalities, deals with CAPTCHAs, and bypasses advanced anti-bot systems. It allows developers to collect large amounts of internet data for e-commerce price monitoring, social media research, machine learning model training and plenty of use cases.
Overall Zenrows performs relatively well on Scrapeway's benchmarks taking top spots in some targets while having some difficulties with others.
Zenrows offers most of the core web scraping API features like headless browser scraping, anti-bot bypass and residential proxy support though uniquely it provides a captcha-solving integration and automatic data parsing.
Pros
- Integrations for Python, Nodejs, Selenium, Puppeteer
- Captcha solver integration with 2Captcha.
- Optional Javascript rendering for scraping dynamic pages.
- Optional auto data parser.
- Web UI player for testing and experimenting.
Cons
- Very high entry point of 69$.
- Credits do not carry over month-to-month.
- Poor scraper blocking bypass without headless browser feature.
- Blocks use when many subsequent scrape blocks are encountered.
