alt Hacker NewsThanks for sharing, interesting project! One thing that stood out to me is that some fairly core features are gated behind a Pro tier. For context, there are prior projects in this space that implement similar ideas fully in OSS, especially around Postgres-backed durable execution:
1. DBOS built durable workflows and queues on top of Postgres (disclaimer: I'm a co-founder of DBOS), with some recent discussions here: https://news.ycombinator.com/item?id=44840693
2. Absurd explores a related design as well: https://news.ycombinator.com/item?id=45797228
Overall, it's encouraging to see more people converging on a database-centric approach to durable workflows instead of external orchestrators. There's still a lot of open design space around determinism, recovery semantics, and DX. I'm happy to learn from others experimenting here.
There are other projects that implement the ideas in OSS, but that's the same in Elixir. Not that we necessarily invented DAGs/workflows, but our durable implementation on the Elixir side predates DBOS by several years. We've considered it an add-on to what Oban offers, rather than the entire product.
Having an entirely open source offering and selling support would be an absolute dream. Maybe we'll get there too.
