CodX Editor
What CodX Editor is
CodX Editor is a free, browser-based workspace for building multi-file web projects. It handles HTML, CSS, JavaScript, JSON, environment, and backend files with syntax highlighting, project-aware suggestions, Emmet-style expansion, and line-aware diagnostics. Live or manual previews include HTML inspection, console output, and clickable diagnostic locations. Projects can be saved in the browser, imported or exported as ZIP archives, and recovered after unsaved work. The editor supports real-time collaboration with host, co-host, and participant roles, waiting-room approval, chat, custom cursors, and file-visibility controls. GitHub OAuth enables repository browsing, file creation and editing, uploads, and commits. Node.js and npm run in a browser WebContainer on the user’s machine, requiring a current Chrome or Edge. The free plan supports up to 24 projects and is funded by advertising. Closing or refreshing the tab ends the Node.js runtime.

Verdict
CodX Editor combines browser-based coding, previews, GitHub access, Node.js, and collaboration at no charge. Its 24-project cap and temporary browser runtime are important constraints for larger or persistent development work.
