Why these tools exist
Every scraping project needs the same boring utilities: check a selector, clean some HTML, flatten JSON, guess what proxies will cost. Most sites that offer them upload your data to a server. These don't. Every tool on ScrapperTools runs entirely in your browser, so client HTML, logs, and API responses never leave your machine.
How ScrapperTools makes money
Display ads and affiliate links to proxy and scraping API providers we'd recommend anyway. That keeps the tools free and lets us keep adding new ones. If you sign up for a provider through a link here, we may earn a commission at no cost to you.
