Minimal tmux popup radar for Codex, Amp, Claude Code, OpenCode, Pi, Gemini CLI, and Auggie.

Ilmari exists for the moment when a tmux workspace has multiple agent panes and
you need to answer three questions quickly:

  • which pane is still running
  • which pane is waiting on you
  • which workspace that pane belongs to

It opens as a tmux popup, inspects the panes you already have running, groups
them by workspace, shows agent state plus a visible output excerpt, and jumps
you straight to the selected pane.

Ilmari is popup-first and observer-only. It does not launch agents, manage
workflows, or own your tmux layout. It gives you a fast index over the agent
sessions that already exist.

What Ilmari Solves

When several agents are running at once, the normal tmux workflow gets noisy:

  • waiting panes are easy to miss
  • finished panes and still-running panes blur together
  • workspaces get split across sessions and windows
  • you end up cycling panes manually just to find the one that matters

Ilmari reduces that to a popup:

  • detect supported agent panes from tmux metadata and output
  • classify panes as running, waiting, finished, terminated, or unknown
  • group panes by workspace path
  • show lightweight git change context per workspace
  • jump to the selected pane and get out of the way

Installation

Cargo (crates.io)

cargo install ilmari

Homebrew

brew install bnomei/ilmari/ilmari

GitHub Releases

Download a prebuilt archive from the GitHub Releases page, extract it, and
place ilmari on your PATH.

From source

git clone https://github.com/bnomei/ilmari.git
cd ilmari
cargo build --release

Popup-First Setup

tmux popup support requires tmux 3.2 or newer.

1. Add a tmux binding

Assuming ilmari is already installed and available on your PATH:

bind-key i display-popup -E -w 90% -h 85% "ilmari"

Reload tmux after editing ~/.tmux.conf:

tmux source-file ~/.tmux.conf

2. Open the popup

Press your tmux prefix, then the bound key.

Typical popup flow:

  • open ilmari
  • move selection with j / k or arrow keys
  • press Enter to jump to the selected pane

When ilmari is launched as a tmux popup, activation returns you to the target
pane and closes the popup.

Configuration

Ilmari currently configures through environment variables.

Variable Purpose Default Notes
ILMARI_REFRESH_SECONDS Main tmux scan cadence 5 Positive integer seconds. Empty, invalid, or non-positive values fall back to the default.
ILMARI_PROCESS_REFRESH_SECONDS CPU and memory sampling cadence 15 Separate from the main refresh so ilmari does not call ps on every redraw. Empty, invalid, or non-positive values fall back to the default.
ILMARI_TUI_PALETTE Primary palette override terminal ANSI theme Takes an 18-slot CSV palette. Takes precedence over ILMARI_PALETTE.
ILMARI_PALETTE Compatibility alias for palette override terminal ANSI theme Used only when ILMARI_TUI_PALETTE is unset.

Examples:

ILMARI_REFRESH_SECONDS=10 ilmari
ILMARI_PROCESS_REFRESH_SECONDS=30 ilmari

Ilmari uses semantic color roles in code, but by default those resolve through
your terminal's current ANSI palette. If you want explicit colors, provide an
18-slot CSV palette override using ILMARI_TUI_PALETTE or ILMARI_PALETTE.

Slot order:

fg,bg,black,red,green,yellow,blue,magenta,cyan,white,bright_black,bright_red,bright_green,bright_yellow,bright_blue,bright_magenta,bright_cyan,bright_white

Accepted color formats:

  • #RRGGBB
  • 0xRRGGBB
  • 0XRRGGBB
  • RRGGBB
  • rgb:RR/GG/BB
  • rgb:RRRR/GGGG/BBBB

Behavior:

  • ILMARI_TUI_PALETTE takes precedence over ILMARI_PALETTE
  • empty or malformed palette values are ignored
  • if neither is set, ilmari uses the terminal's default ANSI theme
