Been using Lindy for a few months now. It's fine. Really.
If your workflow is "get an email, do a thing, mark it done," you're golden. It's cheap, it works, no Salesforce-level bloat.
But try to do anything even slightly off the beaten path? Good luck.
* Want it to handle a conditional approval based on a custom field in your CRM? Nope.
* Need it to parse a slightly weird email format from a legacy system? It'll just... stop.
* Multi-step processes with different branches depending on the data? You're basically building a Rube Goldberg machine out of duct tape.
It's the IKEA furniture of automation. Looks great on the box, but if your wall isn't perfectly flat, you're screwed.
Feels like it's built for the 80% use case and just shrugs at the other 20%. Problem is, in real business, that 20% is where all the complexity lives.
CRM is a means, not an end.
