Krantz Stealth

Local HTTP API that sends requests with real Chrome, Firefox, Safari, Edge, Opera, or OkHttp browser fingerprints.

Feature 01

Authentic Browser Fingerprints

Bundled, up-to-date emulation presets reproduce each browser's real TLS ClientHello and HTTP/2 settings — no hand-rolled fingerprint to keep current.

Feature 02

JA3/JA4 Evasion

Cipher order, curves, extensions and HTTP/2 frame order match the genuine browser, so requests pass fingerprint-based filtering.

Feature 03

Local HTTP API

A loopback HTTP server you drive with simple kp- headers. Works with curl, Python, Node, or anything that speaks HTTP.

Feature 04

Rotating or Pinned Profiles

Pin a specific browser via kp-profile, or send 'random' to round-robin a curated pool of current browsers.

Feature 05

Named Sessions

Reuse cookies and connections across requests by naming a session — ideal for multi-step flows.

Feature 06

Proxy & Redirect Control

Forward through an upstream proxy, cap redirects, force HTTP/1.1, and set per-request timeouts.
