It occupies the small but useful CLI niche of making bad networks reproducible during local development and testing. ### Project history The official GitHub repository was created in June 2022. Its README describes speedbump as a TCP proxy written in Go that simulates variable network latency and documents release binaries, source builds, and a container image. ### Adoption history Official releases started in July 2022 and reached v1.1.0 in November 2022. The repository metadata and README show adoption signals around prebuilt release assets, Docker use, Go documentation, and package-manager availability rather than a large external ecosystem. ### How it is used The CLI is run as a listening proxy pointed at a destination, with options for base latency and wave-shaped latency variation. Developers use it to test how TCP clients and services behave under controlled delay without changing application code. ### Why package nerds care Package nerds care because speedbump is a single-purpose, scriptable network impairment tool: install one binary, wrap a destination, and reproduce latency profiles in CI, demos, or local debugging. It is small enough to package cleanly but practical enough to save bespoke test harnesses. ### Timeline - 2022: kffl/speedbump repository created on GitHub. - 2022: v0.1.0 and v1.0.0 releases published. - 2022: v1.1.0 release published. ### Related projects - The project also publishes a Docker image for container-based use. - Its Go library package can be used programmatically for delaying TCP connections. ### 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:** speedbump - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - MacPorts - speedbump: normalized package name match | MacPorts ports tree: net/speedbump/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 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. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [ip_relay](https://www.automicvault.com/pkg/brew/ip-relay/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [iperf](https://www.automicvault.com/pkg/brew/iperf/) - Shares av.db curated category or tags: cli, latency, networking, tcp. - [proxytunnel](https://www.automicvault.com/pkg/brew/proxytunnel/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [redir](https://www.automicvault.com/pkg/brew/redir/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [rinetd](https://www.automicvault.com/pkg/brew/rinetd/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [stone](https://www.automicvault.com/pkg/brew/stone/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [swaks](https://www.automicvault.com/pkg/brew/swaks/) - Shares av.db curated category or tags: cli, networking, testing. - [tproxy](https://www.automicvault.com/pkg/brew/tproxy/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [iperf3](https://www.automicvault.com/pkg/brew/iperf3/) - Local metadata places this package in an adjacent workflow.
