Hoppscotch is a free, open-source, and privacy-first API development ecosystem that helps developers build, test, and debug APIs faster — right from the browser, no installation needed.
Build APIs at the speed of thought.
Hoppscotch (formerly known as Postwoman) is an open-source alternative to Postman, created by Liyas Thomas while he was still a college student in Kerala, India. What started as a side project to build a lighter, faster API client has grown into a full-fledged API ecosystem used by over 500,000 developers worldwide.
