I've been working for the last 5 years on an alternative called Dagger. Ended up building a company around it.

We started from the ideal state of CI, and set out to build the platform that would support that.

For us this ideal state of CI boils down to 4 things:

- local-first (local execution should be a first-class citizen, with no exception)

- repeatable (the same inputs should yield the same output, with affordances for handling inevitable side effects in an explicit and pragmatic way)

- programmable. my workflows are software. I want all the convenience of a modern software development experience: types, IDE support, a rich system API , debugging tools, an ecosystem of reusable components, etc.

- observable. I want all the information in one place about everything that happened in my workflow, with good tooling to get the information I need quickly, and interop with the existing observability ecosystem (eg. open telemetry)

So Dagger is our best effort at a CI platform focused on those 4 things.

Sorry if this comes across as a sales pitch. When you're building solves a problem you're obsessed with, it's hard to discuss the problem without also mentioning the solution that seems the most obvious to you :)

I've been watching Dagger with great interest, although have not moved production workloads to it (nor, admittedly, even committed an afternoon to setting up any workflows/graphs).

Passive comment readers should be aware that ^shykes here cofounded Docker (my gratitude), so it's really worth a look.

Can anyone comment on the ergonomics of Dagger after using it for a while?

I was just looking at the docs earlier this week to consider a migration but got confused by the AI sections...

    You're not the only one... At some point last year, we discovered that CI/CD workflows and so-called "AI agent workflows" have a lot in common, and Dagger can in theory be used as an execution engine for both. We attempted to explain this - "great for CI/CD and for Agents!". But the feedback was mostly negative - it came across as confusing and lacking focus. So, we are rolling back this messaging and refocusing on CI/CD again. If you haven't checked our docs in the latest 12 hours, it's worth checking again: you'll see clear signs of this refocusing (although we are not done).

    In doubt, I recommend joining our public discord server (https://discord.com/invite/dagger-io) it is basically a support group for CI/CD nerds who believe that a better way is possible, and want to discuss it with like-minded people.

    Thanks for the kind words!
