Sharing diagrams with other people
Diagrammo needs no account. A space is the part you only reach for when somebody else is involved.
If somebody has invited you to a space and you are trying to work out what you have been invited to, this page is the short version. The binding version is in the terms.
The app on its own has no account
This is worth saying first, because the rest of this site says it too. The desktop app and the editor in your browser are complete on their own: your diagrams are plain text files on your own machine, nothing is uploaded, and there is nothing to sign in to. Everything below is optional, and you can ignore all of it for as long as you are working alone.
What a space is
A space holds diagrams and the people you share them with. You all edit the same diagrams, so nobody emails a file around.Diagrammo Cloud is what the service holding it is called.
There is still no sign-up. Your email address is your identity, and signing in means asking for a link and opening it — no password to choose, and nothing to fill in. If somebody has invited you, there is nothing to accept either: sign in with the address the invitation was sent to and the space is simply there.
A space has one owner and any number of members, and each member holds one of three roles.
| Role | What they can do | What it costs |
|---|---|---|
| Viewer | Reads the diagrams in the space. | Always free, however many of them there are. |
| Editor | Creates and changes diagrams in the space. | One per space is free. More is what a paid plan is for. |
| Admin | The person who made the space. Invites people, changes roles, removes members, deletes it. | One per space, and it cannot be handed to somebody else. |
Your copy stays on your machine
Joining a space does not move your work into a browser tab. The app and the web editor keep a local copy of the space's diagrams on your device, so you can keep working with no connection. That copy is yours, it is plain text, and exporting it never depends on paying us. If you are removed from a space, the app deletes that space's local copy the next time it runs — the diagrams belonged to the space, not to your disk.
Showing a diagram on the web is a separate decision
A space is private to its members. Putting a diagram in one does not publish it.Showing a diagram on the web is a deliberate, separate action that turns one diagram into a genuinely public page: anyone with the link can read it, there is no sign-in in front of it, and search engines may index it. You can stop showing it at any time, though a copy somebody else has already saved is beyond anyone's reach.
That is also what makes a diagram embeddable in a documentation site that always shows the current version — seelive links.
What it costs
Paid plans are not on sale yet. An account without one holds up to 25 diagrams, shows up to 5 of them on the web, and owns up to 25 spaces, with one editor per space. People who only read are free and unlimited on every plan — a space that many people read and one person writes never costs anything.
When plans do go on sale they are priced per editor per month, and theterms already set out what happens if you stop paying: nothing is deleted, hidden or made read-only, and your export keeps working.
Been invited to a space?
Open the link in your invitation, or go toonline.diagrammo.appand sign in with the address it was sent to — the space is waiting there, and there is nothing to accept. It all works in a browser; the Mac app is optional, and keeps the same space in step on your own machine.
