Web scraping?using scripts to extract data from websites automatically?is a powerful tool for developers creating AI models or price comparison apps.
But is it legal in 2026? After a series of massive Supreme Court decisions regarding AI training data, the rules have finally solidified.
The General Rule: Public Data is Legal
Courts have generally ruled that scraping publicly available information that anyone can see without logging in is legal. You cannot be prosecuted under hacking laws (like the CFAA in the US) just for automating a browser.
When Web Scraping Becomes Illegal
However, you face severe legal danger in the following scenarios:
- Bypassing Logins: If you must create an account and click "I Agree to Terms of Service" to see the data, scraping it is a breach of contract.
- Copyright Infringement: Scraping articles or images and re-publishing them as your own violates copyright law.
- Denial of Service (DDoS): If your scraper sends 10,000 requests a second and crashes the server, you can be sued for computational damages.
Respecting Robots.txt
Every major website has a robots.txt file outlining what bots are allowed to do. While it is technically a guideline and not law, respecting it helps you avoid IP bans and legal threats from aggressive corporate lawyers.
