Host Excalidraw without installing anything
An endless whiteboard with a pencil-sketch look: architecture doodles, meeting diagrams and workshops, on a link you share without making anyone sign up.
Starting at €2.99/month
Introduction
Excalidraw installed, updated and backed up by us, on a machine in France. A hand-drawn whiteboard, made for sketches, diagrams and workshops. You install nothing and configure no server: the application is online a few minutes after you order, under your own name.
The plan that suits it is App Découverte at €2.99/month incl. VAT — 1 GB of memory. Excalidraw is one of the lightest applications in the catalogue: your browser does the drawing, the server only serves the application and relays shared sessions. That gigabyte covers the relay and the system underneath, with enough room for several boards running at once.
An Excalidraw drawing lives in a .excalidraw file, which is nothing more than readable JSON. PNG and SVG exports can carry the scene inside them: the image you send a client reopens months later as an editable drawing — something proprietary exports do not do. Coming from Miro or FigJam, however, there is no direct importer: you keep the exported images and redraw what still matters.
What Excalidraw can do
A deliberately imperfect line
The sketchy rendering is not just a style choice: a diagram that looks like a draft invites comments on the idea rather than on the alignment of the boxes. That is why it earned its place in workshops and architecture reviews.
Collaboration by link
You open a shared session and send the link: everyone's cursor shows up on the board and edits appear live. Nobody has to create an account to take part.
PNG and SVG that stay editable
On export, the scene can be tucked inside the image file. A PNG pasted into documentation can be dragged back into Excalidraw months later, with every layer intact.
Shape libraries
Public libraries bring ready-made icon sets — cloud infrastructure, UML notation, interface wireframe kits — and you can build your own for the components you keep redrawing.
What people actually use it for
Sketching an architecture before writing it
A developer draws how a request travels between services, exports the SVG and drops it into the repository README. The diagram stays editable instead of becoming a dead image.
Running a remote workshop
A trainer opens a board, sends the link to twelve participants and has them annotate it together during the call. None of them has to register or buy a licence.
Showing a layout without it being judged on colour
An agency presents a page structure as a wireframe. The pencil line makes it obvious that the subject is the layout, so the client comments on where the blocks sit rather than on the shade of a button.
Illustrating the minutes of a meeting
A committee scribbles a room plan while the meeting is going on, exports it as a PNG and attaches it to the minutes sent to the members.
Walking a client through a process
A consultant traces the path of an order, from quote to invoice, live with the person opposite. The drawing becomes the starting point of the next session instead of being copied into another tool.
Hosted in France
In our own datacentre in Nouvelle-Aquitaine, which we operate ourselves. Your boards, infrastructure sketches included, do not leave the country.
Frequently asked questions
Nothing. You choose the application, fill in the fields it asks for — often an email address and a name — and it goes online. Access arrives by email with the address and the credentials.
Not automatically: Excalidraw reads neither the Miro nor the FigJam format. It opens .excalidraw files, plus PNG and SVG files exported from Excalidraw with the scene embedded. In practice you export the old boards as images for reference and redraw the ones still in use — which is quick, since most were never meant to outlive the workshop that produced them.
Yes. The installation includes the collaboration relay: you start a session, share the link, and everyone draws together. The board lives in that shared session, so make a habit of saving it when the workshop ends.
Excalidraw+ adds shared folders, comments, team management and versioned board history. The free application we host is the canvas and the shared editing: it covers sketching and workshops, not managing a library of diagrams over the years.
Yes, they are part of the service. A self-hosted application left un-updated is a security risk, not a saving.
