discontinued Kong Inc. removed the local-only, open-source option in September 2023 (v8.0), requiring mandatory cloud accounts and login. The GitHub repo was flooded with angry issues and the app's rating plummeted. Developers mass-migrated to Bruno and Hoppscotch. Kong partially reversed course, but trust was destroyed and the OSS community never returned.
