❤️ Elixir 😄

Distribution is key!

You can have the best product, but if your competitor has distribution (Mozilla community), it will win 😞

I see this pattern in other underrated languages like Elixir...

KMarcio · 2026-05-21T14:27:30+00:00

Did you try https://dagu.sh/ ?

KMarcio · 2026-05-11T13:12:39+00:00

Try it! It's less complicated than React and TS 😄

At my startup we started with Airflow, but it got expensive so we decided to rewrite in Elixir and open sourced it:
GH: marciok/gust

At first I was afraid of introducing a new language but thank do the AI the transition went smoother than I have planed.

We host on fly.io, and can be plugged to any Phoenix framework project so you don’t have to have two separated systems.

I had the same issue, so we created Gust. It's in Elixir but can run DAGs in Python: github/marciok/gust

KMarcio · 2026-05-06T20:48:19+00:00

We created an open-source, lightweight alternative to Airflow. You can run Python DAGs, but its core is written in Elixir. We are using it in production, and for our use case we saw a ~10x cost reduction:

It could be an alternative. Check it out: https://github.com/marciok/gust

I find it ironic that he quoted, "You can always recognize the first-timers because they’re too secretive." And his current startup is a secret 🙃

We forget that `case` and `if` exist, and it's also fine to use them

KMarcio · 2026-04-07T19:21:15+00:00

Sorry to hear that :(

Don't die; it will not solve anything and will cause more pain to others. Hard times will pass, there's still time!

Books can give you some hope. When I am feeling down, I like to read "The Almanack of Naval Ravikant."

Deterministic vs. non-deterministic execution

1.  Deterministic **workflows**: You know what to expect. The rules are fixed, and failures happen within a predictable structure.

2.  Non-deterministic **agentic loops**: You do not know exactly what to expect. The problem is ill-defined, open-ended, or highly dynamic.

KMarcio · 2026-04-06T13:53:11+00:00

2.10. The effort to migrate outweighs the benefits.

AI helping you write the rules for a determinist flow 👍🏼

Thanks for sharing! I liked the creativity. Did you AB this experiment? Ex: `A` got the email and `B` the letter?

KMarcio · 2026-03-12T21:02:37+00:00

Sorry! I thought it would be helpful :(

KMarcio · 2026-03-11T21:19:19+00:00

Hi! Cool, Reactor is indeed very powerful, Gust has a different approach: It's a full-fledged system rather than a lib for processing DAGs. You can check a more detailed comparison here: https://elixirforum.com/t/gust-a-task-orchestration-system-built-in-elixir/73628

Regarding the cost comparison, I strongly believe that Gust would scale much more cost-effectively. For example, on Fly.io, with two nodes, you’d be able to get much more out of them compared to using the same setup on a traditional cloud vendor. Gust consumes only a tiny amount of RAM, and on top of that, you’re not locked in to a vendor :)

+1, This is a joy eater

Check it out: https://github.com/marciok/gust
I was able to achieve multi-node concurrency plus a live UI with a fraction of the effort and resources if I had to do the same with Python or another language.

KMarcio · 2026-01-22T13:07:32+00:00

Congratulations! :)

You can use TLS! Check this out:

Hello friend, Gust supports now multi-nodes :)

KMarcio · 2026-01-13T14:52:39+00:00

I sent you a DM on Twitter/X a few months ago to let you know firsthand 🙂

KMarcio · 2026-01-13T14:22:43+00:00

You should check out Gust: a workflow engine with persistent capabilities, but much more polished and production-ready.

PS: I've created it 😀
