Deno still has quirks, like not running on ARM processors.

I work on Deno, specifically the CLI. We support both Mac and Linux ARM, though the Linux ARM builds are currently produced by a third party contributor.

If you have specific issues with ARM, I'm certainly interested in fixing those. I don't have any timeline for when we'll add Linux ARM as a binary release target but I'm happy to ensure any ARM-only bugs get the proper attention.

Does that mean deploying Deno to AWS Graviton is an issue currently?

Thats the use case I have in mind to cut costs

I haven't specifically tested it but it _should_ be supported. I don't have easy access to graviton instances at this moment, but I've previously used https://github.com/LukeChannings/deno-arm64 with great success.

As long as your ARM OS is 64-bit, Deno should function properly. 32-bit _might_ be supported, but TBH we don't do any testing of those configurations as far as I'm aware.

Weird, when I run 'file deno' on my ARM Mac I get:

    deno: Mach-O 64-bit executable arm64

...also haven't experienced any problems so far.

How about in Docker on ARM Mac?

No official docker images, but lukechannings maintains ARM/Linux builds and an unofficial docker container that are well supported:
