Hi -<p>I have an app. Certain stages of the funnel require some action, like send text, send email, call certain endpoint.<p>Instead of building everything in code, and for the sake of quicker experimentation (changing copy, adding notifications, etc), I'd like to use some "out of the box" solution:<p>1. A platform that I can send events to. I anticipate about 1,000 events per day.<p>2. Be able to create workflows, that would, based on incoming events and conditions, perform some actions.<p>It looked like Segment is one option, but much more expensive than I anticipated. And it's unclear whether it supports workflows.<p>Re-tool seems to be another option, however also at $75 per each 5,000 workflow runs, would come out expensive, easily over $500/month.<p>I'd prefer open-source solution, or something affordable and in cloud.<p>Thanks!
