The Oban folks have done amazing, well-engineered work for years now - it's really the only option for Elixir. That said, I'm very confused at locking the process pool behind a pro subscription - this is basic functionality given CPython's architecture, not a nice-to-have.

For $135/month on Oban Pro, they advertise:

    All Open Source Features

    Multi-Process Execution

    Workflows

    Global and Rate Limiting

    Unique Jobs

    Bulk Operations

    Encrypted Source (30/90-day refresh)

    1 Application

    Dedicated Support

I'm going to toot my own horn here, because it's what I know, but take my 100% free Chancy for example - https://github.com/tktech/chancy. Out of the box the same workers can mix-and-match asyncio, processes, threads, and sub-interpreters. It supports workflows, rate limiting, unique jobs, bulk operations, transactional enqueuing, etc. Why not move these things to the OSS version to be competitive with existing options, and focus on dedicated support and more traditional "enterprise" features, which absolutely are worth $135/month (the Oban devs provide world-class support for issues). There are many more options available in the Python ecosystem than Elixir, so you're competing against Temporal, Trigger, Prefect, Dagster, Airflow, etc etc.

We may well move some of those things to the OSS version, depending on interest, usage, etc. It's much easier to make things free than the other way around. Some Pro only features in Elixir have moved to OSS previously, and as a result of this project some additional functionality will also be moved.

Support only options aren't going to cut it in our experience; but maybe that'll be different with Python.

There's a lot more of everything available in the Python ecosystem =)

That's totally fair, and I can only speak from the sidelines. I haven't had a chance to review the architecture - would it possibly make sense to swap from async as a free feature to the process pool, and make async a pro feature? This would help with adoption from other OSS projects, if that's a goal, as the transition from Celery would then be moving from a process pool to a process pool (for most users). The vast, vast majority of Python libraries are not async-friendly and most still rely on the GIL. On the other hand, Celery has absolutely no asyncio support at all, which sets the pro feature apart.

On the other hand, already released and as you said it's much harder to take a free feature and make it paid.

Thanks again for Oban - I used it for a project in Elixir and it was painless. Missing Oban was why I made Chancy in the first place.
