Vegeta is an HTTP load testing tool written in Go that can be used as a command in a command-line interface or as a library. The program tests how an HTTP-based application behaves when multiple users access it at the same time{{Cite web |date=May 26, 2022 |title=Load Testing with Vegeta |url=https://www.scaleway.com/en/docs/tutorials/load-testing-vegeta/ |url-status=live |archive-url=https://web.archive.org/web/20211016154329/https://www.scaleway.com/en/docs/tutorials/load-testing-vegeta/ |archive-date=October 16, 2021 |access-date=August 27, 2022 |website=Scaleway}} by generating a background load of GET requests.{{Cite book |last=Eiermann |first=Andreas |url=https://www.worldcat.org/oclc/990058133 |title=Innovations for community services : 17th International Conference, I4CS 2017, Darmstadt, Germany, June 26-28, 2017, Proceedings |last2=Renner |first2=Mathias |last3=Großmann |first3=Marcel |last4=Krieger |first4=Udo R. |date=2017 |isbn=978-3-319-60447-3 |editor-last=Eichler |editor-first=Gerald |location=Cham, Switzerland |pages=83 |chapter=On a Fog Computing Platform Built on ARM Architectures |oclc=990058133 |editor-last2=Erfurth |editor-first2=Christian |editor-last3=Fahrnberger |editor-first3=Günter}} Vegeta is used to generate a sustained, constant number of requests per second in order to discover how long a service can sustain a peak load before dropping in performance.{{Cite book |last=De |first=Brajesh |url=https://www.worldcat.org/oclc/978273106 |title=API management : an architect's guide to developing and managing APIs for your organization |date=2017 |isbn=978-1-4842-1305-6 |edition=First |location=New York |pages=161 |oclc=978273106 |access-date=August 27, 2022 |archive-url=https://web.archive.org/web/20220828040838/https://www.worldcat.org/title/978273106 |archive-date=August 28, 2022 |url-status=live}}

In addition to preemptive load testing, the program can also be used for shadow testing,{{Cite book |last=Welch |first=Nat |url=https://www.worldcat.org/oclc/1056157467 |title=Real-world SRE : the survival guide for responding to a system outage and maximizing uptime |date=2018 |publisher=Packt |isbn=978-1-78862-644-6 |location=Birmingham, UK |pages=137 |oclc=1056157467}} where traffic from a live version of an application is mirrored onto a test version to determine how it handles the same traffic load, without causing potential disruption to the live version of the application.{{Cite web |date=February 5, 2020 |title=Application deployment and testing strategies |url=https://cloud.google.com/architecture/application-deployment-and-testing-strategies#shadow_test_pattern |access-date=August 28, 2022 |website=Google Cloud}} Shadow testing is done in this way in order to analyze anticipated server performance.{{Cite book |last=Qi |first=Lin |url=https://www.worldcat.org/oclc/1225562925 |title=Mobile wireless middleware, operating systems and applications : 9th EAI International Conference, MOBILWARE 2020, Hohhot, China, July 11, 2020, Proceedings |last2=Qiao |first2=Zhihong |last3=Zhang |first3=Aowei |last4=Qi |first4=Hui |last5=Ren |first5=Weiwu |last6=Di |first6=Xiaoqiang |last7=Wang |first7=Rui |date=2020 |isbn=978-3-030-62205-3 |editor-last=Tang |editor-first=Dalai |location=Cham, Switzerland |pages=70 |chapter=Performance Analysis of QUIC-UDP Protocol Under High Load |oclc=1225562925 |access-date=August 27, 2022 |editor-last2=Li |editor-first2=Wuyungerile |archive-url=https://web.archive.org/web/20220828041010/https://www.worldcat.org/title/1225562925 |archive-date=August 28, 2022 |url-status=live}}
