The Middleware Tax
No-code automation tools like Zapier are excellent for prototyping, but they are punitive at scale. You are charged per "task," meaning the more successful and automated your business becomes, the more you are penalized financially by your own infrastructure.
Furthermore, your proprietary business logic is trapped inside a third-party platform. If they raise prices or suffer an outage, your operations freeze.

| Data Privacy | Data passes through 3rd-party servers | Data remains strictly inside your Google Cloud |
