Limits and FAQ
The limits that apply today, and answers to the questions people ask most.
Limits#
These are the limits on the Free plan. Pro raises them; the pricing page has the numbers for every plan.
| What | Limit | Notes |
|---|---|---|
| Diagrams on your device | No limit set by Diagravo | Bounded only by your browser’s storage. Available to everyone, including guests. |
| Diagrams in the cloud | 20 per account | You choose which diagrams sync. Saving to your device always works, even when the cloud is full. Diagrams shared with you do not count. |
| Components in a cloud diagram | 40 | A diagram on your device alone is not capped by the editor; one stored in the cloud holds up to 40 components. |
| Components added with the terminal | 500 per diagram | An add that would take the diagram past 500 components is refused, and so is the whole script it was in. |
| Replication group size | 2 to 20 copies | Create Replication Group makes between two and twenty identical components. |
| Published link per diagram | 1 | Publishing again keeps the same link. |
| Published link watermark | On the free plan | A small “Made with Diagravo” mark on the shared view. |
| Collaborator roles | Editor or Viewer | Invited by email; the person needs a Diagravo account. |
Frequently asked questions#
Do I need an account to use Diagravo?#
No. Building, connecting, editing, playing and exporting all work without an account, and your diagrams are saved on your device. You only need an account to sync diagrams to the cloud, publish a share link, or invite collaborators.
Does Diagravo deploy or provision anything?#
No. Diagravo is for sketching, testing an idea and communicating a design. Nothing you build creates real infrastructure. The Export Code feature generates a starter project you can use as a starting point for your own code.
Is playback a real load test?#
No. Rule-based playback is an illustration driven by the numbers you set: it shows how a request would travel through your components and which ones the traffic you described would overload. It does not model real latency, failures, retries or concurrency, so it is not evidence that a real system will perform.
Where are my diagrams stored, and can I lose them?#
Every diagram is saved in your browser on your device. Clearing site data, using a private window, or switching browser or device means they will not be there. To keep them safe, sign in and sync a diagram to the cloud (up to 20), or use Export JSON to keep a file.
Can anyone else see my diagrams?#
Only you, unless you publish a diagram (which creates a public, read-only link that anyone with the link can open) or invite someone as an editor or viewer. Guests are not tracked: there is no account, cookie or identifier, and your diagrams stay in your browser until you choose to sign in and sync. The only thing counted is anonymous daily totals (for example, how many visits pressed Create Diagram), and nothing is sent if your browser asks not to be tracked.
How do I move a diagram to another device?#
Sign in on both devices and sync the diagram to the cloud, then open it from My Diagrams on the other device. Without an account, use Export JSON on one device and File, Import on the other.
Why does a component show a red or amber dot before I press Play?#
The dots compare the traffic your clients describe with each component’s capacity settings and update as you edit, so you can see an overload without playing anything. Hover the dot for the figure. Raise the component’s capacity, add more components behind a load balancer, or lower the client’s active users.
Why does nothing happen when I press Play in Rule-based mode?#
Rule-based playback starts at Client components. If there is no Client connected to anything, the Console says so and nothing moves. Add a Client and connect it to the rest of the diagram.
Can I use Diagravo on a phone or tablet?#
Yes. The documentation, the pricing page and shared diagram links work on any screen. On a tablet the Components list becomes a slim rail and the script panel opens over the canvas, and everything works by touch. On a phone the header is just the logo, the name and your account. File, Export, View and Share are buttons along the bottom that open their options as lists, and a small Play, Pause and Stop tab (with a menu for the playback mode) floats over the diagram. A diagram opens to look at: pan and zoom, and tap a component to see its details. Tap Edit to build: Add opens a searchable list of components, and once you select a component the bar offers Settings, Copy, Connect, Group and Delete. Building a large diagram is still easiest on a tablet or computer.
Is Diagravo free?#
Yes. The Free plan is free forever and needs no account to start. Pro is a paid plan and Team is planned; the pricing page shows what each includes. The limits on this page are the Free plan’s.
