I work at Boomi, on their Flow product (similar to this project), and we open source everything in our product, except for our core workflow engine - https://github.com/manywho (our pre-acquisition name if you're wondering).

The community part is hard to generate though... there's a lot of enterprise in the workflow space.

StandardLib also has a community, though not sure how big it may be.

Pricing is a key differentiator. My market research included a pricing analysis and Boomi was priced well above Zapier and other similar solutions.

I think there is a LOT of money ceded to less expensive offerings by 10 or 15 providers (including Boomi) all chasing the same enterprise market. I would've expected tiered pricing to emerge to a greater extent, but haven't seen it.

I watch this space very closely.
