Typhoeus

Hydra enables concurrent HTTP requests, significantly improving throughput for batch operations, as shown in the example queuing 10 requests in parallel.

Supports various backends like Rails cache, Redis, and Dalli for efficient response reuse, reducing network calls and latency with configurable TTLs.

Allows chunked response handling via on_body callbacks, enabling large downloads without memory overload, demonstrated in the huge ISO file example.

Provides easy mocking of HTTP responses with Typhoeus.stub, simplifying integration tests without external servers, as detailed in the testing section.
