I ended up building a Zapier replacement using NodeJS. I built this because I was annoyed that in order to integrate with Sendgrid, I would need to have Zapier. I wanted to avoid yet another company knowing about me and my data.
Sharing my blog post here in case other IndieHackers want a customizable, free/low cost alternative to Zapier for data movement.
