Req is a simple yet powerful Go HTTP client library with chainable APIs, supporting HTTP/1.1, HTTP/2, and HTTP/3. It offers built-in debugging dumps, automatic retries, auto-decoding, authentication, file download/upload with progress callbacks, and TLS fingerprint impersonation to bypass anti-crawler detection.

Use cases

• make http requests in go with a simple chainable client
• test apis from go code instead of curl or postman
• scrape websites that block bots via http fingerprint impersonation
• download files with progress callbacks and parallel segments
• debug http requests by dumping full request and response content
• retry failed requests with exponential backoff
• use http3 or force a specific http version

When to choose

• you want a batteries-included Go HTTP client with retries, auth, and debugging built in
• you need HTTP/3 support or automatic protocol negotiation
• you need to impersonate browser TLS fingerprints for crawling
• you want minimal-code API testing with MustXXX helpers

When to avoid

• you need only the standard library and want zero dependencies
• you are building a server rather than a client
• you need a general-purpose scraping framework with parsing and scheduling
