What to look for
- Ease of use: Is a visual builder with blocks enough, or do you also want to add your own code?
- Connections: Are there ready-made connections to your apps, such as email, calendar, CRM or shop?
- Billing: You often pay per run, task or credit. Calculate with your real volume.
- Privacy: Where is the provider based, where is data processed, is there a data processing agreement or a self-hosted version?
- Control: Can you add approval steps, logs and limits?
