Neptune

Neptune is a native Rust terminal providing GPU rendering, workspaces, split panes, and tools for AI coding agents.

Neptune is a native Rust terminal built for focused work without webviews, featuring independent shell sessions, GPU rendering, and a quiet workspace interface. It is designed for developers who use local shells, SSH workspaces, and AI coding agents like Claude Code, Codex, OpenCode, pi, and Oh My Pi. The terminal includes workspaces, tabs, split panes, and groups with drag-and-drop organization, as well as scrollback, terminal search, selection and clipboard tools, and a command palette. Users can configure custom keybindings in TOML and choose from 715 built-in themes. What sets it apart is its project mode and session resumption, where lead agents plan work, start and follow other agents in separate terminals, track pull requests, and maintain shared notes. Neptune is open source under the MIT license.
