Note that this is fundamentally different from the Astral acquisition. At the end of their announcement, they stated: > Cirrus CI will shut down effective Monday, June 1, 2026. And earlier in the article: > Joining OpenAI allows us to extend the mission we started with Cirrus Labs: building new kinds of tooling and environments that make engineers more effective, for both human engineers and agentic engineers. It isn…

Just want to note that we will continue maintaining and improving our virtualization solutions actually with even greater attention. SaaS options like Cirrus CI and Cirrus Runners will eventually wind down so we can focus on incorporating pieces internally.

What are your plans for tart licensing going forward?

We have AI companies constantly fear-mongering that their next model is somehow too dangerous to release. But they just continue to go on an acquisition spree. This just confirms to me that we are no where near AI being able to write any complicated software. I mean, if it could woudln't OpenAI just prompt it into existence? ;)

I'm guessing you're referring to this recent report of the security vulnerabilities Mythos found and submitted patches for? That just seems like they don't want the negative press and/or liability if their new model ends up being used to create 0-days that cause widespread damage.

That sounds like a British phrase for pimping.

Not to sell Tart short (it is quite good), but it's "just" a wrapper around Virtualization.framework with a few extra pieces. This is the kind of thing that Codex driven by experts _should_ be able to build very easily.

Yes, but it’s also currently the best one. They have OCI compatible Mac VM images that are prebuilt. It’s quite good.

You’ll be pleasantly surprised. Updates in the coming weeks.

> In the coming weeks, we will relicense all of our source-available tools, including Tart, Vetu and Orchard under a more permissive license. We have also stopped charging licensing fees for them.

It looks like OpenAI has no clue what to do and does what every software company without a plan does: create new dev tools and a new dev stack. So they want an integrated solution with CI, Python packaging and vibe coding. That is a $100 million valuation at best, not a $1 trillion one.

yeah super confused, it looks like some tools to manage vms in ci? what is unique about that vs lxc or docker or apple's native container cli?

interesting that was what i thought this was, it keeps boggling my mind the sums being paid for what really could be built by experienced devs on their own teams

I've moved most companies away from using others stuff Today we use Hertzner and OVH and roll out our own solution whenever possible. Running lean and mean. Depending on such third party services is a trap.

What software do you use to run your CI?

not op either, github actions, self hosted runner on bare metal with lxc containers for each runner.

Cost savings are insane and the speed of latest amd epycs are miles ahead of the default ci instances on github and other places.
