Built for teams that need more than a checkbox.
A CAPTCHA platform should help operators see risk, control rollout, and keep integration predictable.
Privacy-first verification
Designed around minimal data collection and clear enterprise controls.
Multi-engine defense
Choose visible, invisible, and advanced challenge engines by site and business risk.
Actionable analytics
Track pass rate, risk detection, hostnames, browsers, regions, and site-level trends.
Per-site policy
Keep low-risk flows smooth while increasing cost for suspicious traffic.
Deployment-aware delivery
Designed for predictable loading across distributed application traffic.
Integrate BotFlush with existing production flows.
BotFlush supports familiar widget and server-side verification patterns, so existing CAPTCHA integrations can be adapted with targeted changes.
Drop-in widget
Load the BotFlush script, render a site key, and receive a token after successful verification.
Server-side verification
Send the token and your secret key to the verify endpoint before accepting protected actions.
Migration path
Existing checkbox-style deployments can often be adapted by changing the script source, keys, and verify endpoint, then testing callback and error handling.
