I made a per-pane Codex status line for WezTerm

[un4gt]

Hey everyone 👋

I've been using Codex CLI in WezTerm a lot, often with multiple panes open at the same time.

One thing I kept missing was a quick way to see what each Codex session is actually doing — which model it's using, reasoning effort, how much context is left, token usage, etc. — without switching around or digging through session files.

So I ended up building WezTerm Codex Status Line:

https://github.com/un4gt/wezterm-codex-status-line

It adds a status bar underneath each Codex pane and can show things like:

• model + reasoning effort
• working directory + Git branch
• remaining context
• cumulative input/output tokens
• cache hit rate
• estimated cost

It also supports multiple Codex panes at the same time, with the status tracked separately for each session.

The data comes from Codex's local session logs, so it doesn't make any extra model/API requests just to update the status line.

There's a browser-based interactive preview where you can change the fields, icons, colors, and one/two-row layout, then download the config and use it locally:

https://un4gt.github.io/wezterm-codex-status-line/

Installation is basically:

npx --yes wezterm-codex-status-line@latest install --no-title-bridge

or:

uvx wezterm-codex-status-line install --no-title-bridge

Then add this to .wezterm.lua:

config.status_update_interval = 500
require("codex_statusline").setup()
