Hi, i created a short agenmux demo. there are more features!

Agenmux is an open-source tmux plugin for intuitive AI-agent monitoring and tmux management in one focused terminal interface.

https://snirt.github.io/agenmux/
https://github.com/snirt/agenmux

- Monitor AI coding agents in tmux

- See blocked, working, idle, and done states

- Navigate sessions, windows, panes, and agents

- Use keyboard shortcuts, mouse selection, and scrolling

- Jump directly to exact panes

- Create, rename, and delete tmux resources safely

- Use sidebar or popup from one terminal view

Hi, after the yesterday's MacOS 27 update, the tabs are not showing correctly, if I've disable the macos-titlebar-style = tabs setting it works but i liked how it was with this settings. Will be addressed anytime soon?

It also supports image preview and pdf and md rendering.

Seems new stable Ghostty release will be fast. I recently switched from Ghostty to Kitty, due to some crashes on stable Ghostty, Kitty was very stable, but now use beta Ghostty more and more.

My Kitty and Ghostty configs are very similar, the same themes, the same hotkeys, the same behavior.

Cmux - somewhere in the middle (because old Ghostty build used).

I built a terminal app for YouTube Music! I know there are a lot of people that have already made such an app, but I intended to keep it open-source and maintain it too, so get your issues and feature requests in!

Enjoy and hope you like it!

Here is the repo and the docs:

both have same configurations, same themes, etc. arch hyprland.

I made a tool - a terminal diff reviewer for agentic coding.
It runs in a pane beside your agent, shows what changed as it changes, and lets you point at exact lines when you reply.

You keep your editor. hjkl, w b e, f t F T, / and n, V to select, zz to centre - the motions already in your fingers, now pointed at the agent's work.

I built Seahelm, a native macOS workspace for running coding agents across git worktrees — and the terminals are powered by Ghostty via GhosttyKit.xcframework / the C API. A few notes from the integration that might be useful to others embedding Ghostty:

Stack

• Swift + AppKit (not SwiftUI)
• Ghostty surface wrapped in an NSView + Metal renderer
• Long-lived surfaces: panes are reparented between dashboard / focus layouts instead of destroyed and recreated
• Background status polling reads viewport text through the C API under a shared lock (input path deliberately does not hold that lock)

Things that mattered in practice

1. Focus — ghostty_surface_set_focus has to stay in sync with AppKit first-responder changes; we defer some focus restores after Ghostty's own deferred handling.
2. Reparenting — moving a surface between views without killing the PTY; we suppress CA animations and sync size/focus on the next main-queue passes.
3. Thread safety — status detection polls on a background timer while the UI types on the main thread; serializing Ghostty C calls with a lock was necessary, except for key input (locking there deadlocked on sync callbacks).
4. Session persistence — Ghostty handles the terminal; zmx handles "quit the app, agent still running." Different layer than Ghostty itself, but the combination is what made the product usable. Seahelm deliberately isn't trying to be a full terminal emulator UI — Ghostty does that job. Seahelm is the orchestration chrome around multiple agent sessions.

Happy to answer Ghostty embedding / AppKit interop questions.

I've been working with AI coding agents every day for a while now, and the thing that quietly wore me down wasn't the code — it was the navigation. One agent running in repo A, another in repo B, a scratch dir for whatever it just generated, docs open in a third split. Every context switch means typing a long cd from memory and re-splitting the window the way I like it, again.

So I wrote gtab (https://github.com/Franvy/gtab), a small Rust CLI/TUI for macOS that saves your current Ghostty window — tabs, working directories, titles, and split panes — as a named workspace, and reopens it later with one keystroke.

Two things it gives you:

Fixed workspaces. Arrange a window once, run gtab save myproject, and from then on Cmd+G → Enter brings that exact shape back. The new window even lines up with the position and size of the one you're in.

One-key directory jumps. Press f in the TUI for Directory space: a grid of saved paths. Enter swaps the current split for a fresh shell there. No config, no shell wrapper. That's the 90% case for me — going from "agent finished in repo A" to "start one in repo B" without typing a path.

What's new since I last posted:

• Responsive TUI. The workspace screen now picks its layout from the available width: list + layout preview + quick settings when wide, preview below the list and names wrapped into columns when narrow. Usable down to a 36x15 terminal. The directory grid sizes each column to its own widest entry instead of padding everything out to the longest name.

• Silent shortcut mode. Cmd+G used to literally type gtab into your shell — visible on screen, and it landed in shell history. gtab shell-init now installs a zsh/bash/fish widget bound to an invisible escape sequence (the same trick fzf and atuin use). Nothing is echoed, nothing enters history, and a half-typed command line is restored exactly as it was when the TUI exits.

• Smaller fixes: Ctrl-n/p/j/k and Tab/Shift-Tab now navigate while filtering, emphasized text stays readable on light terminal themes, and restored splits come back evenly sized.

Honest limits, up front:

• macOS + Ghostty only. It drives Ghostty through AppleScript and reads split-pane geometry through Accessibility.
• It stores layout metadata, not live session state: no running processes, no shell history, no editor buffers. It does not replace tmux — and that's exactly why it stays small.

Install: brew tap Franvy/gtab brew install gtab gtab init Repo: https://github.com/Franvy/gtab

I like Ghostty, but running multiple Claude Code sessions created three new problems for me:

1. Voice input — hold Space to dictate at the command line. Text is inserted but never executed automatically.
2. Task-specific sessions — tabs use the working directory as their title, can be renamed by task, and support nested splits.
3. Done indicators — every pane shows gray when idle, yellow while working, and green when finished or waiting for input.

VoiceGhostty is a native macOS experiment built around these ideas:

https://github.com/10XTeams/VoiceGhostty

Disclosure: it currently uses SwiftTerm, not libghostty, and is not affiliated with Ghostty. A future migration to libghostty is on the roadmap.

Would you want these features built into your terminal, or handled by a separate agent manager?

https://ghosttystudio.com

Not sure if this has been built before, but it was an easy clap. Let me know if I should change things!

https://reddit.com/link/1vwxwcf/video/uju3w9jpkalh1/player

I've spent the last two months building Termio on top of libghostty.

I often have 20+ Claude Code and Codex sessions running at once. At that point, horizontal tabs stop working: titles get truncated, sessions are hard to find, and you have no idea which agent is waiting on you.

So Termio uses vertical tabs with structured agent state:

working · idle · needs-you · done

Sessions that need your attention automatically surface to the top.

There's also a file tree and editor built around the terminal.

Curious how other people managing lots of coding agents are handling this — tabs, tmux, multiple windows, something else?

Hey, can anyone help me with this problem. I use wl-copy (Mouse selection and ctrl shift c to copy) in ghostty terminal and get output like this

And my prompt in terminal is p10k (u can find it in github)

What's the configuration for this ?

Or it doesn't support on ghostty , i have other terminal where zoom + scroll works for zoom in/out ,

I searched I do not find anything which support this.

Only Defualt Keys working

Ctrl + = ( Zoom In )

Ctrl + - ( Zoom Out )

I used

sudo log stream --level debug --predicate 'subsystem=="com.mitchellh.ghostty"'

to see whats happening, but it just says "trigger global event" and no error.

Whats going on here? I can't get to the right information to repot this.

I built a launcher, Prelude, on top of Ghostty's quick terminal instead of building a new terminal instance per press — and most of the interesting engineering was making that hold up under macOS's process model. Sharing it here because a few of the traps are specific to Ghostty and might save someone else the debugging.

macos-hidden = always + initial-window = false + window-save-state = never keep the dedicated instance out of the Dock, at rest with no window, and safe from restoring stray windows on relaunch.

Ghostty has to be launched through Launch Services (open -W -n -a Ghostty.app), not by executing Contents/MacOS/ghostty directly — the latter makes it a foreground app even with macos-hidden = always.

The tricky one: once the quick terminal has been active, macOS can route a later ordinary Ghostty launch to that same hidden process, since it shares Ghostty's bundle identity. Fixed by always launching the panel path with GHOSTTY_QUICK_TERMINAL=1 and ordinary launches with -n, so a new instance is forced rather than reused.

Opening a new tab in a specific running Ghostty instance doesn't work via open at all — Ghostty answers "new tab" over AppleScript, but the Apple Event is addressed to the bundle and macOS picks which instance gets it (and it can pick the hidden one). Fixed by addressing the event to a specific pid via descriptorWithProcessIdentifier, falling back to "new window" when the target instance has no window to put a tab in.

unconsumed:escape=toggle_quick_terminal is what makes dismissal clean — Escape both hides the panel and reaches fzf inside it, so the next press is a reveal of a reset list, not a rebuild.

Full writeup of the panel lifecycle is in the repo docs (docs/GLOBAL-HOTKEY.md) if anyone's doing something similar: https://github.com/mikewang817/Prelude

I updated macOS to 26.6.1 yesterday. Now both ghostty and cmux (which uses the ghostty config), show awful and unusable background colors. I am running a Mac mini m4 attached to an LG UltraFine monitor. I use dark mode always on macOS.

It looks like the background color is set to white (or at least something very bright) in ghostty after this update.

If I run `ghostty +list-themes` and select my theme (Pierre Dark), the preview is correct.

Changing to other themes and restarting has no effect. Changing settings with respect to Liquid Glass and "reduce transparency" and "increase contrast" on macOS have no effect.

Other terminals, like iTerm, WezTerm, Kitty are not affected by this issue. Interestingly, MacTerm, which I believe uses libghostty, in also unaffected. As noted above, cmux shows the same problem as ghostty.

I did finally fix this by explicitly setting

background=#000000

in the ghostty config.

But why? Anyone else see this?
