FAQ
- Solver chain: 2Captcha vs Capsolver vs NextCaptcha?
- 2Captcha: most reliable, mid price. Capsolver: AI-first, fast. NextCaptcha: cheapest. Build a fallback chain for resilience.
- Why does my reCAPTCHA v3 fail despite getting a token?
- v3 scores client behaviour. Token from a CAPTCHA service may score low. Target site decides what score to accept; high-security sites reject.
