This is amazing and might be exactly what I’m looking for my own weirdo retro tooling that sometimes needs to run over ssh but also expect a “GUI” experience… any metrics on the overhead this might add to, for instance to a hello world type program?
I use libghostty for Trolley[0], which packages TUIs as desktop apps, like Electron does for web apps.
It really is quite an amazing piece of software. I just wrapped it in a useful GUI and a bundle/package CLI and it just works. Even on Windows. Kudos to the Ghostty developers.
I think your github readme is really missing a picture/screenshot to quickly understand what is the experience like. I.e. if your app is mainly about adding the chrome (as in the surrounding UI pixels) around the TUI, then it would be good to show what is the chrome like.
Nah, I think it’s pretty clear. It would look like a terminal emulator. Just like how Electron looks like a bunch of browser widgets - because it’s literally a single-web-app browser.
This is a pretty cool idea. Kind of a neat distribution hack if all you have is a TUI (and not a full GUI). Curious whether you know of any success stories yet
You mention that Android/IOS support is possible. I hope that you can please add these support properly as your project matures.
Asking this because I would love to have a cli tool where I can just point to for example golang codebase from any device (mac/windows/linux) etc. and thanks to golang's cross compilation simplicity, have it be compiled for android (well linux arm fwiw) and then have it all be compiled into a single android apk.
And if you do that, I would love to have something like zenity but for android so as to abstract the cli behind a nice gui for mass-adoption.
This is almost a million dollar problem as there are so many good cli tools and its incredibly easy and versatile to make a gui even with scripts on top of that cli but Android/Ios usually don't have that versatility.
I used ghostty for the shell in my agent-manager tool (think something like https://air.dev/ but in SwiftUI. One architectural detail i'm still going back and forth on is: who should own the PTY?
If embedded Ghostty owns it, now i have to have some kind of workaround to instrument what's happening inside the terminal - signals, stdout/stderr events, return code etc.
If my parent agent-manager app owns it, now i don't have the nice clean small interface to ghostty (i'm a fan of John Ousterhout style narrow but deep interfaces, pulling complexity down rather than pushing up to parent).
Not sure if any other ghostty embedders might have advice. It's on my todo list to task a an agent to "gh repo clone" a few ghostty using shells and report on their arch.
The C file is small enough to read (over a few minutes.)
I got to about line 5 and realized: I’ve never seen quite that technique for embedding a font via an autogenerated header before. I’m more used to Windows resources; this seems to generate a byte array in CMake code. I’m somewhere between horrified and impressed, in that I feel we’ve finally discovered a cross platform binary resource embedding solution.
Well, I originally used C23's #embed directive (https://en.cppreference.com/w/c/preprocessor/embed) but GCC in Nixpkgs doesn't support C23 (or I'm holding it wrong) so I dropped back to this. The better long term solution is #embed.
I've definitely used C23 via Nixpkgs long ago at this point, did you use the `gcc` package and `-std=c23`? Both unstable and 25.11 should support it on all currently packaged GCC versions.
For completeness, there's also the somewhat common way of creating an object file directly from the binary using objcopy. The object file ends up with 3 symbols with names based on the input file. For instance, a binary file level0.map yields: _binary_level0_map_start, _binary_level0_map_end, _binary_level0_map_size.
These can be used in the application through external declarations; and you include the object file in the linking step, like any other object file.
You can use `xxd` from the vim package to generate these. You'll find out pretty quickly that this is only suitable for small resources: gcc and clang blow up in both time and space on very large literal arrays. If you need to ship more than a few megabytes, find a different technique.
I used this technique for awhile, but it was too problematic for my use case. Now, I use https://github.com/lief-project/LIEF -- among other things, this project can modify Windows PE, macOS Mach-O, and Linux ELF binaries to add resources to them, then offers an API to read them back later. It's a little different for each format, but it's capable of doing all three and I was able to build a cross-platform resource-bundling system that doesn't care how big the resources are.
Yeah xxd is the correct answer. If you don't want to install a dependency and have Lua installed, or if you're just feeling a little bit frisky, you can use my function which is Production Ready™.
Xxd = function(name, input)
if not name:find'^[_%a][_%w]*$' then error('bad name: '..tostring(name)) end
local ans = {
'const unsigned int '..name..'_len = '..(#input)..';',
'const unsigned char '..name..'[] = {',
}
local t = {}
for i=1,#input do
table.insert(t, ('0x%02x,'):format(input:byte(i)))
if #t == 16 then -- 16 columns per row. arbitrary, change this if you want
table.insert(ans, table.concat(t))
t = {}
end
end
if #t ~= 0 then
table.insert(ans, table.concat(t))
end
table.insert(ans, '};\n')
return table.concat(ans, '\n')
end

Feels like Lua is a more exotic dependency. I used to use xxd but this gets problematic when files grow (and they don't need to grow much at all), objcopy is much faster (which I didn't think would matter much, but it did) and don't have the same issues that accidentally opening the .h file in your editor or code-searching having to traverse that mess.
Yes, you'd want to gitignore it and exclude it from search etc. but you still have size issues etc. See gucci-on-fleek's comment on objcopy above for usage.
And as a Windows programmer the use of a method called DrawTextEx surprised me :)
A really neat sample. Shows the power of the ghosttty library very well. The author chose well with their other libraries, it’s the kind of demo that lets the code actually demo what to trying to without much else getting in the way. Rather inspirational to wrote my own terminal app now.
> I’m somewhere between horrified and impressed, in that I feel we’ve finally discovered a cross platform binary resource embedding solution.
Maybe I'm misunderstanding your comment about having "finally discovered" that...
For to me embedding binary resources in source files is nothing new at all? It was definitely done in the early JavaScript days for a variety of reasons.
Arguably early basic listings that had lots of DATA text lines were already doing that. Maybe not the most portable but we're talking about the 70s and 80s here and definitely binary data in source code.
Games for the Atari ST and Amiga, for example, could partially share at least some of their source code and it wasn't uncommon to encode binary inside sources, including... Fonts! Back then fonts were not reused from one game to another.
Heck, I've done in Java (and Java is cross platform) in the past: quick visual debug tools for Java GUI apps to toggle a debug mode showing something not dissimilar to a HUD. Pixel-perfect fonts encoded in .java source files.
I really don't think it's anything new.
P.S: I'm pretty sure it's done like for some fonts in the Linux kernel too.
I built my own macOS terminal app over the last two weeks using swift/appkit + ghostty's zig library.
I basically just wanted vertical tabs and notifications for when AI agents (claude code, codex) are finished.
I already use it as my main terminal over iTerm.
It's a fun project since I use my terminal all day, so I always have ideas for how something could be improved or polished. AI can do the chore work of figuring out how to impl some bugfix or UX polish, and I manage the last 10%.
This would have been too much work to maintain for fun before LLMs.
My notification hook pipes an OSC 777 (title, body) message into /dev/tty, Ghostty handles/ingests it and then emits the event for my terminal app to do things like craft a macOS notif and style the tab/pane of the originating terminal.
I tried the osascript solution first but had some issues, iirc no good way to focus the originating terminal pane on notif click.
Something I never figured out is why Claude Code's "Notification" hook waits minutes to fire. I had to use the "Stop" hook for actual end-of-response timing.
> iirc no way to focus the originating terminal pane on notif click.
Yeah mine has the same issue - it just brings up the script editor. It's not as much of an issue for me since I'm rarely running more than a single Opencode instance at a time.
Could definitely see that being useful if you were running quite a few agents to let you hone in on the correct terminal window/tab quickly though.
Yeah, exactly. I have so many agents running these days. 1-2 per project.
Often one is polishing a plan file for the next feature/bugfix (claude), and the other is reviewing it to give feedback (codex). And that is my life now. But on the upside, it's trivial to maintain sideprojects now.
I switched to Ghostty a few months ago and it's become one of the apps I never close. The rendering speed is noticeably better than iTerm2, especially with large log outputs. Excited to see libghostty enabling projects like this — the idea of packaging TUIs as native desktop apps is really compelling for indie developers.
I have an idea of a terminal emulator where you could maximize panes but using a nested structure, does anyone know of one?
Standard "Zoom" features in tmux or iTerm2 only maximize the single active pane to the full window, hiding everything else. If I have a layout like this:
_____________________
| | B |
| A |---------|
| | C |
|_________|_________|
And I expand B, I want A to hide, while B and C remain visible together. Then I can create a new nested workspace in there and later zoom out when I’m done.
This should be simple any time you have panes in a binary tree split view.
The hard part is the UX: making it clear that we're in a zoom state (esp with nested zooms), somehow showing the split-pane tree so that user knows what container will be filled when they zoom, etc.
Fork ghostty and get claude to one-shot it so you can see if you like the idea.
I don't need my terminal emulator to support tabs, windows, or session management. My WM manages tabs and windows, and I use tmux for sessions, which also gives me a scrollback buffer, selection, clipboard, search, etc. This combination allows me to use any simple terminal emulator, such as urxvt, st, and now foot, without issues.
Ghostty didn't appeal to me, but I might give this a try. It's good that OSC support is planned. A plugin-like system, similar to st's but less cumbersome, would be nice to have.
It's comical how much time I've spent convincing people that tabs are a window manager feature not an application feature. People in the Alacritty issue on the subject were pissed!
I've heard this a lot on HN over the years but it doesn't make much sense to me. Some thoughts:
1. App tabs improves UX for 99.999% of users who aren't using a WM with a good tab solution (if one even exists).
2. WM tabs means launching a new app instance for every tab you might want vs having lightweight app tabs.
3. App tabs can do all sorts of app-level things and UX polish that dumb WM tabs can't do because they are so general. My terminal emulator tabs show a badge count of bell notifications, can be dragged around into groups, or dragging into other tabs as split panes. My browser tabs show you which tab is playing music and can impl right click -> mute.
4. I bet even the biggest WM tab cheerleader still uses browser tabs.
5. WM tabs are a different concern than app tabs, not a replacement. WM tabs are useful when you want tabs and the app doesn't provide a good tab metaphor or when you want to tile/group app instances a certain way. That doesn't mean it's not useful for the app instances themselves to have app tabs when it makes sense.
Agree on all the points, except 4. There are even people out there who use lynx as their primary browser :)
Although while I usually like tabs for most apps, I don't use tabs for terminal and rely either on window manager or tmux. I guess the difference is that I often want a mix of tabs and having multiple terminals side by side, whereas I don't really need that for a browser (or very seldom)
Sway had the better, though often tedious, WM tab solution that I've tried. Niri had a useless one.
I really tried to love sway splits and tabs for terminal windows. But I finally admitted I'd rather just alt-tab to a few different terminal apps, each with its own concern (maybe one per project, this one for my remote machine), and best of all, each with its own internal tabs.
That said, tabs in kitty and tmux, for example, are so basic that you don't necessarily lose much if you were to use WM tabs instead.
On the other hand, tabs in iTerm2, Ghostty, Cmux, probably macOS Terminal -- a bit more powerful and intuitive since you can do things like drag them, and they can show info like terminal state. And in some of those apps, they can be displayed vertically which is my favorite.
I would love tabs for Spotify. I just discovered I can at least open new windows from the linux YouTube music client by middle clicking, a revelation !
Every application (or concept) can introduce “tabs”, but it means something wildly different for that particular application. Tabs (or instances) in an application immediately bumps into the concept of state (statefull vs stateless) in applications.
Sometimes, it makes perfect sense. The reason tabs made sense for web browsers since 2004 is because each web page could be thought of as a “stateless” instance of an application. You’re not asking for “tabs”, you wish every application could be “Stateless”. Stateless is a beautiful thing, until you understand what state is, and who needs to manage it.
If every “tab” of Spotify had no idea what the other “tab” is playing and you had to switch back and forth between tabs to pause-and-play songs, that would be a bug, not a feature. While 2 “windows” playing audio (if you instruct them to) is expected.
Interesting you mention tmux because it itself resembles a terminal emulator. It has its own terminal feature matrix that controls what your parent emulator can render. It sounds like you aren’t using tabs and splits in tmux but it does include them.
It sounds like you could get away with using a tool like https://zmx.sh which only handles session persistence (attach/detach). It also uses libghostty but only for state restoration on reattach.
On tiling WMs I use rxvt-unicode with no window decorations, no gaps, 1 px border, no scrollbar. Then tmux does the rest, namely tabs and splits. Automatic session saving has been a life saver on more than one occasion.
This is amazing and might be exactly what I’m looking for my own weirdo retro tooling that sometimes needs to run over ssh but also expect a “GUI” experience… any metrics on the overhead this might add to, for instance to a hello world type program?

Does it have any extra controls? And is it using native windows (as opposed to Electron)?

It's not really what you want but in a similar vein check out: zoom.el
https://github.com/cyrus-and/zoom
I guess it's also the kind of thing where screen real-estate is a must otherwise when you're at the "top-level" it would look weird-ish.
Wouldn't you want a hide option rather than a fullscreen option? so hide A?
When I use zellij, i just move A to a new tab temporarily
You can do this with i3
I love seeing an `AGENTS.md` in open source projects.
It's now my #1 heuristic to know if the team is on the right track.

I have plans to add it to my game (SDL).
I’m seriously interested in this. I wonder if i can use this along some decent gui library and an llm to vibe-code a SecureCRT replacement.
SecureCRT is awesome but it’s crazy expensive :(
This looks interesting.

On the other hand, tabs in iTerm2, Ghostty, Cmux, probably macOS Terminal -- a bit more powerful and intuitive since you can do things like drag them, and they can show info like terminal state. And in some of those apps, they can be displayed vertically which is my favorite.
I like to manage tabs and windows through tmux and it suits my workflow very well. What are you going to do now?
Are there any good, non-tiling window managers that support tabs? (I struggle with tiling ones like i3 because I am a small-brained mouse user)
Fluxbox has tabs and is a stacking window manager.

Maybe you'd like Niri?

I mean, macOS supports tabs now. I wouldn't call it "good" though.
Yes, we need tabs for RDR2 and Spotify.
I would love tabs for Spotify. I just discovered I can at least open new windows from the linux YouTube music client by middle clicking, a revelation !
Every application (or concept) can introduce “tabs”, but it means something wildly different for that particular application. Tabs (or instances) in an application immediately bumps into the concept of state (statefull vs stateless) in applications.
Sometimes, it makes perfect sense. The reason tabs made sense for web browsers since 2004 is because each web page could be thought of as a “stateless” instance of an application. You’re not asking for “tabs”, you wish every application could be “Stateless”. Stateless is a beautiful thing, until you understand what state is, and who needs to manage it.
If every “tab” of Spotify had no idea what the other “tab” is playing and you had to switch back and forth between tabs to pause-and-play songs, that would be a bug, not a feature. While 2 “windows” playing audio (if you instruct them to) is expected.
> Tabs (or instances) in an application immediately bumps into the concept of state (statefull vs stateless) in applications.
Agreed, and this is why tabs need to work at the app level, not window manager/os level.
That said, for Spotify specifically, it can already tell what I'm playing on an entirely different device. I think they can handle tabs.
Interesting you mention tmux because it itself resembles a terminal emulator. It has its own terminal feature matrix that controls what your parent emulator can render. It sounds like you aren’t using tabs and splits in tmux but it does include them.
It sounds like you could get away with using a tool like https://zmx.sh which only handles session persistence (attach/detach). It also uses libghostty but only for state restoration on reattach.
A poor man's version of session persistence can even be managed with tmux plugins like tmux-resurrect and tmux-continuum.
On tiling WMs I use rxvt-unicode with no window decorations, no gaps, 1 px border, no scrollbar. Then tmux does the rest, namely tabs and splits. Automatic session saving has been a life saver on more than one occasion.
