stylobot

open source bot detection

Detect and stop scrapers, bots, and API abuse.

You get all the data. You make the decisions. No black boxes.

Zero PII by design — nothing stored, GDPR compliant without trying.

by

13+ detectors analyse every request. You get the full picture.

Heuristics, behavioural analysis, fingerprinting, and optional LLM detection. You get probability scores, confidence levels, risk bands, detector breakdowns, signals, and reasoning. Block, log, challenge, or build custom workflows. All open source.

Drop-in integration

YARP proxy or ASP.NET Middleware adds bot intelligence as HTTP headers. Or use the JSON API.

Full transparency

Every request returns scores, confidence, signals, detector breakdowns, and reasoning.

Zero PII

Nothing stored. No IP addresses, no fingerprints, no cookies. GDPR compliant by design.
