The useful parts. The trade-offs.

Why consider it

Scripts can become approachable internal tools

Unlimited executions suit frequent internal jobs

What to keep in mind

Community limits constrain larger deployments

Advanced observability and enterprise controls are paid

How to use it well

Wrap one existing script with clear inputs and outputs before building a larger flow. Store connection settings as resources, test failure behavior, and expose a small form only after the underlying operation is safe to repeat.

Track who can edit code versus who only needs to run an application. The free edition allows unlimited executions but caps workspaces, users and groups. Compare SSO and guest requirements carefully, and budget separately for the infrastructure and external services your scripts consume.
