## Summary

Visual builders excel when events and branches are stable and operators want pixel control. Prompt-built automations excel when you know the outcome but not every step. Brew generates multi-step flows from description; Customer.io and Klaviyo remain canvas-first with AI assists.

## Choose your builder style

Start with the failure mode: if your team never finishes the canvas, try prompt-native generation in [Brew](https://brew.new). If compliance requires signed-off diagrams, stay canvas-first in [Customer.io](https://customer.io) or [Klaviyo](https://www.klaviyo.com).

## FAQ

### Can agents build automations?

Brew documents MCP tools for flow creation. Most incumbents require human canvas work with API triggers at the edges.
