Show HN: Free hosted open-source alternative to Zapier/Airflow

I am using D3. AFAIK nobody has used it for worfklow visualization so far: https://www.titanoboa.io/visualizing-workflows.html

I've used Zapier a fair amount and I wrote an article about Airflow so I have a fairly good understanding of that too.

I would never really consider them alternatives though? To me Zapier is a low/no code tool that offers a bazillion integrations and Airflow is a workflow orchestration tool.

So comparing to both of them confuses me and I guess choosing one would give you a more nieche audience but one that you can connect better to as well.

This is a very good point.

My current line of thinking is: A workflow is a workflow is a workflow. Titanoboa is built the way that pretty much everything it shuffles is data - and either it can be big (Airflow) or the steps can have side effects (iPaaS/Zapier).

The "no code" is achievable since adding more predefined steps is not that hard (there's not that many at the moment though) - see for instance https://github.com/mikub/titanoboa/wiki/Getting-Started-with... - you dont code, you just fill in properties, so it is very straightforward, pretty much like Zappier.

My aim in the iPaaS space is more at the enterprise level, where the predefined steps won't do anymore and you have to custom develop them anyway - so in that are I think Titanoboa shines since you really can rapidly prototype steps on the fly, a bit like Repl.it and Zapier together...

I agree that it might be good to pick one audience, at this stage I am just experimenting if somehow I can market to both and don't mess up and confuse both groups.

I stop watching it when he said “here I can add any Maven dependency”

How does this compare to Prefect? https://medium.com/the-prefect-blog/why-not-airflow-4cfa4232...
