Features

A complete overview of atrium's capabilities.

Terminal that remembers the whole room

Split panes, tabs, and persistent workspace layouts
Crash-proof journaling of layout, scrollback, working directories, and environment
Auto-resume for compatible AI tools when you reopen the app
Global zoom, draggable panes, and a sidebar that remembers its state
Tab layout diagrams — miniature color-coded maps of each tab's pane arrangement

File browser that follows your work

The file tree follows the focused terminal's branch and worktree
Git status is visible inline, including modified, deleted, added, and conflicted files
Gitignored files stay visible, but fade into the background
Drag files into panes to open them as editor splits

Editors built in, not bolted on

Monaco-powered code editing — the same engine behind VS Code
Rich markdown editing with comments, table of contents, and Mermaid diagrams
Consistent file icons, pane headers, and branch-aware titles

Source control without leaving the app

Stage, unstage, diff, commit, fetch, pull, and push from a built-in git panel
Inspect commits and drill into per-file diffs in place
See incoming and outgoing commits at a glance
Open source control as its own split, right next to the code you're changing

Built for AI-native workflows

Launch Claude Code, Codex, and other installed tools from a built-in launcher
Detect active agent sessions and reconnect them after restart
Surface adapter identity through pane accents and workspace visuals
Add support for new CLI AI tools with a script-based adapter SDK

Agents that can work together

Most AI terminals give each agent a shell. atrium gives them a shared workspace.

Built-in MCP tools let agents list panes, inspect workspace context, read visible pane output, and write to other panes
atrium:// provides a common protocol for pane, workspace, command, hook, and MCP operations
Agents can coordinate across splits instead of working in isolated terminal sessions
Visibility and scope controls keep inter-pane communication constrained to the workspace you intend

Worktrees without the ceremony

Create branches and worktrees from inside atrium
Switch the file tree by focused pane, not by manual navigation
Copy selected ignored files into new worktrees with .worktreeinclude
Keep parallel branches and experiments open without losing context

Repo search

Search file contents and filenames with regex, case sensitivity, whole word matching
Results stream in real-time as files are scanned
Include/exclude glob filters
Cmd+click results to open files in editor tabs

Lightweight, native, and customizable

Built with Tauri, not Electron
~8 MB on disk
Built-in themes, plus custom themes from ~/.atrium/themes/
Remappable keybindings, including send-text actions for PTY input
