I like dbos architecture much more than temporal since it is much easier to operate on small team.
But dbos doesn't have opensource release of web ui, which is most critical part for a workflow management tool.
Since competitor have all of itself opensource I don't think dbos will have a chance.
We are a happy user of DBOS. I’ve been building out a lightweight TUI for managing our DBOS application internally, since we have workflows with tens of thousands of steps. I know the team is working on improving conductor for this use-case, but our internal TUI handles it pretty well for now. Hoping to open source it, but the code is a wreck atm. Anyways, I say all this to say, DBOS has a good client that can communicate with the instance easily, so building out a UI that fits your specific needs should be fairly simple.
We'll be releasing self-hostable Conductor (the web UI) soon--stay tuned!
If that comes, it will be truly great.
looking forward to it!
