marcterm
A fast and powerful terminal emulator tailored for parallel coding and AI agents, built with Freya and Rust.
marcterm is a fast, minimal terminal emulator for people who like to keep several coding sessions going at once. Group your work into projects, jump between sessions from the home view, and split any panel into as many panes as you need. Everything is keyboard driven, so your hands never have to leave the home row.
It is also a great fit for agentic workflows. Run AI coding agents like Claude Code, opencode or Codex side by side in split panels, and keep each agent on its own git worktree with live diff stats in the sidebar.
It is written in Rust on top of Freya, a native GUI framework. That means real GPU rendering, low input latency, and a small footprint. The full source code is available on GitHub.
