history

Project history and usage

speedbump is a Go TCP proxy for adding predictable variable latency to network connections. 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.
