## What it is
A Go HTTP client library with a net/http-like interface that lets you select specific browser TLS fingerprints (Chrome, Firefox, Safari, etc.) for outgoing requests. It supports HTTP/1.1 through HTTP/3, header ordering, proxies, cookie jars, and WebSocket connections to evade TLS fingerprint-based bot detection.

## Use cases
- scrape websites that block requests based on TLS fingerprints
- make HTTP requests that look like they come from Chrome or Firefox
- bypass Cloudflare-style TLS fingerprint detection
- send requests with custom header ordering through proxies
- use browser-like HTTP/2 and HTTP/3 fingerprints from Go
- call the client from Python or Node.js via FFI bindings

## When to choose
- you need to mimic real browser TLS/QUIC fingerprints in Go
- your scraper is blocked despite matching user-agent headers
- you want an http.Client-compatible API with fingerprint control and proxy support

## When to avoid
- you just need a standard HTTP client without anti-detection needs
- you are not working in Go or one of the provided FFI language bindings
- your use case involves bypassing protections you are not authorized to test
