ChatML

ChatML is a desktop tool for orchestrating Claude Code sessions. It is built around parallel sessions, code review, cost tracking, and pull request workflows in one interface, with an emphasis on keeping agent activity visible while work is in progress.

The app lets a user scope tasks and delegate them to agents in isolated Git worktrees, so multiple features can be handled at the same time without branch conflicts or constant context switching. It includes a dashboard for seeing all running sessions at a glance, showing status, progress, and what each agent is working on. ChatML also provides a built-in diff viewer with inline comments, and it supports Quick, Deep, and Security review modes before changes are merged. Real-time cost and token tracking is available per session, with budget limits. Other documented features include an integrated terminal, a command menu with keyboard shortcuts, multi-workspace support, a file browser with tabs, activity notifications, and support for MCP servers. It also includes Linear integration, a skill library, plan mode with approval, sub-agent spawning, and extended thinking.

ChatML is described as a native desktop application for macOS, Windows, and Linux. The interface and implementation stack are listed as Tauri for desktop, Rust for the backend, Golang for the API, and Next.js for the UI. The project is 100% open source and uses the GPL-3.0 license. The site also says it is built in public and backed by the community.
