## What it is
Surf is an advanced HTTP client library for Go with fluent, chainable API design. It supports browser impersonation (Chrome/Firefox), JA3/JA4 TLS fingerprint emulation, HTTP/3 over QUIC, and middleware for web automation and scraping.

## Use cases
- scrape websites that block bots
- make http requests that look like chrome
- bypass cloudflare with go http client
- send requests with custom ja3 tls fingerprint
- use http3 quic from go
- rotate proxies for web scraping in go
- impersonate firefox headers and tls in go

## When to choose
- you need to evade anti-bot detection with accurate browser fingerprints
- you want a fluent, feature-rich alternative to net/http in Go
- you need HTTP/2/HTTP/3 with fine-grained protocol settings
- you need proxy, retry, and middleware support in one client

## When to avoid
- you only need simple HTTP requests without fingerprinting
- you are not using Go
- you need a scraping framework with parsing/extraction built in
- impersonating browsers for abusive purposes is not acceptable in your context
