Questions

Pricing questions usually come down to plan fit and workspace ownership.

The answers below cover billing cadence, plan changes, supported diagram types, and what happens when a workspace reaches a limit.

How does yearly billing work?

Yearly billing uses discounted annual pricing. Pro is billed at $72 per year and Team at $800 per year.

Can I upgrade or downgrade later?

Yes. You can change the plan for a workspace as your team or diagram volume changes.

Which diagram types are included today?

TinkerDiagram currently supports Entity Relationship Diagrams, Mermaid diagrams, and Flowcharts.

Who is billed for a workspace?

Billing is managed at the workspace level, so plan limits and invoices apply to the workspace you subscribe for.

What happens if I hit a plan limit?

The app will stop the action that exceeds the current workspace plan and guide you to the billing plans page when an upgrade is needed.

Next step

Choose a plan based on how the workspace is being used today, not on future features.

Free works well for getting started. Pro and Team are there when diagram size, workspace usage, or collaboration needs move past that baseline.
