MarCode

MarCode is a web GUI for coding agents. On top of a solid foundation, MarCode brings performance optimizations, new integrations, and a refined experience:

• Claude Code CLI as the default and primary provider
• Jira Cloud integration (OAuth 2.0, sprint browsing, @PROJ-123 mentions in composer)
• GitLab support alongside GitHub (auto-detected from remote origin)
• Preview diff display for proposed file changes
• Incremental state updates for smooth, non-blocking UI during agent work
• Additional directories in composer — add extra directories to agent context per thread
• And much more

Installation

Warning

MarCode currently supports Codex and Claude. Install and authenticate at least one provider before use:
