USE CASE 1

Use the successor project 'hey' (linked from this repo) to send load to an HTTP or HTTPS endpoint and measure throughput and latency.

USE CASE 2

Migrate any existing scripts or CI jobs that reference 'boom' to the 'hey' repository, which is the actively maintained replacement.

So what is it?

Boom was an HTTP and HTTPS load testing tool written in Go, intended as a simpler replacement for ApacheBench, the classic web server benchmarking utility. The repository has been abandoned and the README consists only of a notice saying the project has moved to a different repository under the name "hey." The author also notes a naming conflict with another project called boom and asks users to switch to the new location. No feature documentation, usage instructions, or other details remain in this repository.

Copy-paste prompts

Prompt 1
This repo (boom) has moved to 'hey'. Show me how to install hey and run a load test against my local API server with 200 concurrent workers and 5000 total requests.
Prompt 2
Using the hey tool (the replacement for boom), how do I benchmark an HTTPS endpoint and output results as a latency histogram?
Prompt 3
How do I integrate hey (formerly boom) into a CI pipeline to fail a build if my API's p99 latency exceeds 200ms under load?
