Nucli is an agents-first terminal for macOS, Linux and Windows. It launches the agent CLIs you already use in real terminal tabs and organizes them by project.

Features

• Projects and workspaces with any number of agent and shell tabs, split panes and a terminal panel per project
• Automatic agent detection with live status, notifications and resumable conversations
• Review what agents change: live git diffs, staging, commits, a commit graph, and a file view you can edit in place
• A fast square monospace UI in Rust, with themes, tree-sitter highlighting and a command palette for everything
• A settings page, backed by plain JSON files you can also edit
• No telemetry, no network calls

Installing

Download the build for your system from Releases.

• macOS: open Nucli-*.dmg and drag Nucli.app to Applications. Builds are not notarized, so run xattr -dr com.apple.quarantine /Applications/Nucli.app once.
• Linux: unpack nucli-*.tar.gz and run nucli. It needs Vulkan drivers and libxkbcommon-x11.
• Windows: unpack Nucli-*.zip and run nucli.exe.

On macOS and Linux, ./scripts/install_latest_github.sh (needs gh) installs the latest release.

Building

Requires a recent stable Rust. On Linux, also the development packages listed in .github/workflows/build.yml.

1. git clone https://github.com/denipolis/nucli.git
2. cd nucli
3. cargo run

A debug build is called Nucli Dev and keeps its own settings and data, so it is safe next to an installed Nucli. ./scripts/package.sh builds the release archive for your system into dist/.
