How's Dramatiq been for you in production? Any gotchas or standout features compared to other task queues?

we had a few issues with arq that we used before, which made us switch to dramatiq earlier this year. @fvoron can probably give you some insights.

I really like this and it's on our to-do list for Appear. I'd also like some way to visually attribute components in the UI., i.e. 'powered by'.

I love your frontend choices, especially @EffectTS_! :) I don't love your backend choices (except @resend, which I love). When will the Effect virus hit v2 of the backend? 🤩

Same tech-stack but + @polar_sh 🙃

We're fully open source as well

Do you guys use microservices for scheduling or queue or it's all monolith ?

am really curious on how to create email templates and using dramatiq.A blog would be really useful for @FastAPI community

Such a simple stack. 😍

Python is awesome

We also share the same sentiment. github.com/exospherehost/exo… is not possible without support from open source ecosystem
