NMOX Studio — an open-source IDE for web development, built on the Apache NetBeans Platform and released under Apache 2.0.
Its distinguishing idea is the Task Rack: build, test, lint, serve and deploy tools appear as devices you patch together with cables, so a pipeline is something you wire rather than configure. Around it sit five studios for the work a web developer actually does — projects, databases, APIs, smart contracts and infrastructure — plus 87 language grammars, 93 built-in learning spaces, and a full interface in thirteen languages.
