What is pylon?
Pylon IDE is a web-based integrated development environment that originated from the Cloud9 v2 project. It provides a full-featured code editor with syntax highlighting for many languages via the ACE editor, an integrated terminal, and a plugin architecture for extensibility. The IDE runs as a Node.js web server (default port 3131) accessible from any browser. It supports modern Node.js versions (>= 22.22.2) and installs via npm, Docker, or the provided shell script. Authentication options include built-in basic auth (username/password flags) and compatibility with Connect middleware for custom auth. The project is licensed under GPL-3.0 and works on iPad Pro with keyboard adjustments.
