Try the real path

See a decision before you integrate.

This live simulation uses a rate-limited playground key, sends the same payload as the SDK, and records the request in the production analytics stream.

playground → /api/challengelive

{

apiKey: bs_live_demo_playground,

behavior: human-like signals,

result: Ready to run a real test request.

}

Everything a security layer should be. Nothing it shouldn't.

Featherweight by design

The widget ships lightweight by design, smaller than one product photo. Your Core Web Vitals stay untouched.

Cryptographic verification

Every pass issues a short-lived signed JWT. Your backend verifies in one call. No secrets in the browser.

Behavioral analysis

Mouse curvature, keystroke cadence, pointer entropy. Behavioral signals make automation hard to fake.

Honest analytics

Live dashboards fed straight from the production database. No sampling, no painted numbers.

Edge-close verification

Optimized for low-latency verification., keeping protection invisible.

Adaptive scoring

Rule-based today, learning tomorrow. New signals plug in without breaking your integration.

The honest comparison

Why teams switch.
