## What it is
A special build of curl (and libcurl) whose TLS and HTTP/2 handshakes are identical to real browsers like Chrome, Edge, Safari, and Firefox. It can be used as a drop-in command-line tool or linked as a library to evade TLS/HTTP2 client fingerprinting.

## Use cases
- make curl requests that look like a real browser
- bypass TLS fingerprinting blocks when scraping
- test how a server fingerprints HTTP clients
- fetch sites that block non-browser HTTP clients
- integrate browser-like TLS handshakes into a scraper
- debug JA3/HTTP2 fingerprint differences

## When to choose
- you need HTTP requests indistinguishable from Chrome or Firefox at the TLS/HTTP2 level
- you want a curl-like CLI or libcurl replacement for fingerprint-sensitive endpoints
- you're scraping services that fingerprint clients

## When to avoid
- you just need ordinary HTTP requests without fingerprint evasion
- you need full browser behavior like JavaScript execution - use a headless browser instead
- you need a pure-Python solution rather than a compiled binary
