hatoo

hatoo is an independent open-source developer whose public GitHub presence centers on high-performance, developer-oriented networking tools. The publisher’s single catalog entry, oha, is a command-line HTTP load generator that re-imagines the classic rakyll/hey benchmark with a terminal-based animated dashboard. Written in Rust for speed and safety, oha fires configurable volumes of concurrent requests against a target URL, then renders real-time latency bands, throughput curves, and error counts directly in the console. The tool is routinely used by back-end engineers to smoke-test REST, GraphQL, and static-file endpoints during continuous-integration pipelines, by DevOps teams to validate autoscaling rules before production traffic surges, and by security researchers who need a lightweight, scriptable traffic cannon for reproducible stress scenarios. Optional features include HTTP/2 and HTTP/3 support, custom headers, POST payload replay, and keep-alive connection pooling, all controlled through familiar POSIX-style flags that slot neatly into shell scripts and GitHub Actions workflows. Because the binary is self-contained and cross-compiled for Windows, macOS, and Linux, operators can drop it into containers, cloud shells, or local laptops without further dependencies. hatoo’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the latest upstream build and permitting batch installation alongside other utilities.
