The README describes autocannon as an HTTP/1.1 benchmarking tool written in Node.js, inspired by wrk and wrk2, with support for HTTPS and HTTP pipelining. The project reached a long-lived 7.x series and published v8.0.0 on 2024-10-14. The repository remained active into 2026, with thousands of GitHub stars and hundreds of forks. ### Adoption history autocannon's adoption follows the Node.js server ecosystem: it is distributed through npm for global CLI installs or library use, and the Homebrew formula packages the CLI for users who prefer system package managers. Its popularity comes from being easy to run against a local URL while still exposing enough controls for serious testing: connection counts, pipelining, duration, request bodies, headers, HAR input, worker threads, rate limits and JSON output. ### How it is used The basic CLI form is autocannon [opts] URL. Defaults are intentionally simple, such as 10 connections and a 10 second run, but the README documents many options for duration, request count, concurrency, pipelining, warmup, headers, bodies, TLS certificates and output formats. Programmatic usage imports the autocannon package and passes an options object, which makes it useful for benchmark scripts and project-local performance checks in Node.js repositories. ### Why package nerds care autocannon is package-nerd useful because it is a small, installable benchmark executable that competes culturally with native tools such as wrk while staying in the Node toolchain. It is one of the standard quick checks for HTTP service throughput in JavaScript projects. Because it needs no daemon, config file or credentials, the packaging surface is clean: install Node, expose the bin, and let users point it at a URL. ### Timeline - 2016: Repository and npm package are created on 2016-03-31. - 2021: v7.x releases continue the mature CLI/API line. - 2024: v8.0.0 is published on 2024-10-14. ### Related projects - The README explicitly names wrk and wrk2 as inspirations. - autocannon is commonly compared with HTTP benchmarking tools such as ab, wrk and hey, though its official docs emphasize its Node.js implementation and API. ### Sources - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** autocannon - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [node](https://www.automicvault.com/pkg/brew/node/) - Runtime dependency declared by Homebrew. - [ali](https://www.automicvault.com/pkg/brew/ali/) - Shares av.db curated category or tags: benchmark, cli, developer-tools, http. - [apib](https://www.automicvault.com/pkg/brew/apib/) - Shares av.db curated category or tags: benchmark, cli, developer-tools, http. - [autobench](https://www.automicvault.com/pkg/brew/autobench/) - Shares av.db curated category or tags: benchmark, cli, developer-tools, testing. - [goku](https://www.automicvault.com/pkg/brew/goku/) - Shares av.db curated category or tags: cli, developer-tools, http, testing. - [gor](https://www.automicvault.com/pkg/brew/gor/) - Shares av.db curated category or tags: cli, developer-tools, http, testing. - [hey](https://www.automicvault.com/pkg/brew/hey/) - Shares av.db curated category or tags: benchmark, cli, developer-tools, http, testing. - [mockserver](https://www.automicvault.com/pkg/brew/mockserver/) - Shares av.db curated category or tags: cli, developer-tools, http, testing. - [moco](https://www.automicvault.com/pkg/brew/moco/) - Shares av.db curated category or tags: cli, developer-tools, http, testing. - [autocannon](https://www.automicvault.com/pkg/npm/autocannon/) - Same normalized package name appears in another local ecosystem.
