version 0.1.0 · free trial

Two commands and you're running.

The Mac download is signed and checked by Apple, so it opens normally — no security warnings, no right-click workaround. Every file comes with a fingerprint you can verify.

installing

$ unzip kosa8_0.1.0_darwin_arm64.zip
$ sudo mv kosa8 kosa8d /usr/local/bin/

$ kosa8 daemon start
$ kosa8 run alpine echo hi
hi

checking it's genuine

$ spctl -a -vv /usr/local/bin/kosa8d
accepted
source=Notarized Developer ID

$ shasum -a 256 -c checksums.txt
kosa8_0.1.0_darwin_arm64.zip: OK

don't take our word for it

Check it's genuine yourself

Your Mac can confirm the download came from us and hasn't been altered. Run the command on the left. If it says anything other than Notarized Developer ID, don't run the program.

That output is from the actual published file, checked after downloading it.

which download

What you get on each system

The part that actually runs programs uses a feature built into Apple Silicon Macs. On everything else, kosa8 becomes a remote control for a Mac that's doing the work.

Your computer	File	Runs things itself?
Mac with Apple chip	`darwin_arm64.zip`	Yes — everything
Mac with Intel chip	`darwin_amd64.zip`	No — connects to one
Linux	`.deb .rpm .apk .tar.gz`	No — connects to one
Windows	`windows_*.zip`	No — connects to one

We'd rather you knew this before downloading than after. On Windows or Linux you can still drive everything from your usual terminal — the work just happens on a Mac elsewhere.

What isn't finished

Rough edges in this version

Apple Silicon Macs only for the part that runs programs.
Shared folders are slower than we'd like. Reading and writing files in a shared folder runs at about a third of full speed. Most of that is unavoidable — it's the cost of the sealed machine — but we set ourselves a target we haven't hit.
You can't pay us yet. The trial works; paid plans aren't switched on.
No app store of ready-made images, and no desktop window — it's a terminal tool.

What works well

Saving a machine mid-task, bringing it back, and copying it — tested end to end on real machines.
Controlling what each assistant can see and reach.
Eight ready-made assistant setups, and a tamper-proof activity record.
42 of the 48 docker commands work unchanged.
