CAPTCHAs have failed for 20 years

4 hours ago

CAPTCHAs were created to distinguish humans from bots by challenging capabilities machines lacked.
Each CAPTCHA generation (distorted text, harder text, image grids) was eventually solved by machines through advances in OCR and machine learning.
Modern anti-bot systems shifted from solving challenges to probabilistic risk scoring based on browser fingerprints and behavior.
With the rise of legitimate browser agents, the focus is now on verifying identity rather than testing capabilities.
Web Bot Auth allows agents to cryptographically identify themselves, enabling trust-based access without CAPTCHAs.
Browserbase is developing agent identity solutions to move away from the endless CAPTCHA arms race.
