FAQ

Quick answers to questions we hear often.

Can I use Flero without writing code?

Yes. The visual editor, the node catalog and the AI builder cover most automations. For something specialised, the Code node runs JavaScript, Python or Dart.

Which languages does the Code node support?

JavaScript (the default), Python and Dart. Pick one per node.

Can a workflow call another workflow?

Yes. Use the Sub-Workflow node. You can also select part of a workflow and choose Convert selection to sub-workflow.

Are workflows versioned?

Yes. Each save creates a version. Only one version is active, and that is the one triggers run. Activate an earlier version to roll back. See Versions and activation.

Can I move workflows between workspaces?

Yes. Export the workflow as JSON and import it in the other workspace. Credentials are not in the file, so bind them again after the import. See Import and export.

Are there templates?

A few. The editor's node panel has a Templates card with two prebuilt workflows and every other workflow in your workspace. A full gallery is not available yet. See Templates.

Can expressions do maths or call functions?

No. Expressions look values up, such as {{ $node["Get Order"].output.total }}. Operators and functions are left as text. Use a Set, Data Transform or Code node for calculations. See Expressions.

Does Flero send my data to AI providers?

Only when a workflow uses an AI node, or when you use the AI builder. The node sends what you put in its prompt to the provider you choose (Anthropic, OpenAI, Google or Ollama).

How do I control AI costs?

Set monthly limits per workspace under AI budgets. Each run's AI cost shows in Logs.

Is there an API?

Yes. You can start runs and manage workflows with an API key. See API.

How is my data separated from other workspaces?

Every workspace-scoped request is filtered to workspaces you belong to. Members of one workspace cannot see another workspace's workflows, executions, variables or Workspace-scoped credentials.

Google and Microsoft sign-in may be available on your instance. Check the sign-in page.

Can I export my execution history?

Yes. In Logs, export the current view as CSV or JSON, up to 10,000 rows.

How long are executions kept?

90 days by default. Organization admins can change it under Settings → Data & Privacy. See Data & privacy.

What's the difference between draft, active, inactive and archived?

Status	Triggers armed?	Can run from the editor?
Draft	No	Yes
Active	Yes	Yes
Inactive	No	Yes
Archived	No	No. Restore it first.

See Archive and restore.

Can two people edit the same workflow at once?

See Collaboration.

Invite them to the workspace. See Inviting members.
Or export the workflow JSON and send it. They import it into their own workspace.
For a decision only, use an Approval node set to Email: the approver gets a link that works without signing in. See Public approval links.

Is the Viewer role read-only?

Not yet. Viewers can edit and run workflows like editors. They cannot add Knowledge documents. See Roles & permissions.

Where does Flero store secrets?

In credentials, encrypted and separate from workflow JSON. Secrets are not included in exports. Put shared values in workspace variables marked Secret.

Can I test a workflow without touching real services?

Yes. Use sandbox mode, which runs against mock data. You can record real responses as mocks. See Mock data.

Where do I report bugs?

Use Feedback or Help in the sidebar profile menu. Include the execution ID and the exact error text.
