Profiles

Profiles define the fingerprint target that OCCLUDE normalizes your traffic to match. Each profile encodes the exact TCP, TLS, and HTTP/2 parameters of a specific browser and OS combination.

Available profiles

OCCLUDE ships with profiles for the most common browser/OS combinations. Each profile matches the fingerprint of the specified browser version running on the specified operating system.

Profile	Browser	OS	Tier
windows11	System (TCP only)	Windows 11	Free
chrome-132	Chrome 132	Windows 11	Pro
firefox-134	Firefox 134	Windows 11	Pro
edge-132	Edge 132	Windows 11	Pro

Profile TOML format

Profiles are defined as TOML files. The TCP section is available in the free tier; TLS and HTTP/2 sections require Pro.

Custom profiles

You can create custom profiles by capturing traffic from a target browser. Place your custom profile TOML in the profiles directory and reference it by name.
