What is Hoppscotch?

Hoppscotch is an open-source API development ecosystem originally created as Postwoman. It is maintained by the Hoppscotch team and has gained over 67,000 stars on GitHub. The platform is available in three forms: a web app at hoppscotch.io, a desktop application for Windows, macOS, and Linux, and a CLI tool for terminal and CI/CD integration.
