Propmpt-genned Rust shell is 13x the Ghostty size

I was one of the happy early Warp users. Hands down it was the best shell I ever used. Even the early preview was packed with useful dev-features more than any other shell I ever used.

Two years after they pivoted to AI platform it's now 805mb.

``` 805M /Applications/Warp.app 62M /Applications/Ghostty.app ```

Performance,startup time and memory usage matter more in terminal apps than almost anywhere else.That's why people react strongly to this.

Why does the on-disk size matter for any of that?

ykurtovOP10d ago

Because it will load into RAM. And RAM cost money. Also, quite hard to upgrade on the laptop

The entire executable isn’t loaded into RAM.

And are laptops a primary deployment target?

More code to load from disk to memory, and while it may be fast, it’s not instantaneous.

SSDs can read at gigabytes per second, and only the used portions are paged into memory.

Anything else?

...and you could probably shave off 20 MB from Ghostty because it is distributed as universal binary (does that even make sense in 2026)?

    ghostty: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable     x86_64] [arm64]
    ghostty (for architecture x86_64):      Mach-O 64-bit executable x86_64
    ghostty (for architecture arm64):       Mach-O 64-bit executable arm64

E.g. the complete app bundle is 62 MB, of that the executable is 40 MB, but that contains both ARM and x86 code.

Intel Macs are still going to be usable, viable computers for at least another 5 years. It will be a decade before they pass into the night of vintage computing enthusiasts like PowerPC Macs did.
