Excalidraw alternative to Miro: an open-source whiteboard that opens instantly

Why buyers actually switch from Miro to Excalidraw

People reach for Excalidraw over Miro when the overhead of Miro exceeds the size of the task. For a quick diagram, logging into an enterprise canvas is friction, not help.

1. You just want to draw something

Miro requires an account and workspace before you draw a box. Excalidraw opens at a URL with nothing to set up, which is exactly right for a fast architecture sketch or a diagram in a PR.

2. Data control and encryption

Miro is proprietary SaaS. Excalidraw is open source with end-to-end encrypted shared rooms and a self-host option, which many engineering teams need for internal diagrams.

3. Light and fast

Miro can get heavy on large boards. Excalidraw stays fast and light, and its hand-drawn style invites rough thinking rather than pixel-perfect output.

Deep dive: Zero-friction whiteboarding

Excalidraw's whole appeal is the absence of setup between you and a diagram.

No account needed

Open the site and draw; share a link to collaborate. There is no signup wall before you are productive.

Encrypted collaboration

Shared rooms are end-to-end encrypted, so a quick collaborative sketch does not send your architecture to a third party in the clear.

Deep dive: When Miro is the right call

Facilitated workshops

For structured sessions with voting, timers, templates and many participants, Miro's tooling is genuinely ahead — this is its purpose.

Enterprise governance

Miro offers SSO, admin controls and integrations that large organizations require for a sanctioned collaboration tool.

Who Excalidraw is actually for

1. The engineer sketching architecture

Anyone who wants a quick diagram without logging in gets exactly that, and can drop it in a PR.

2. The security-conscious team

Teams that cannot send internal diagrams to a SaaS can self-host or use encrypted rooms.

3. The small team on a budget

Groups that do not need workshop tooling avoid paying for a heavy enterprise canvas.

Migration walkthrough: how to switch from Miro to Excalidraw

Step 1: Open Excalidraw

Go to the site — there is nothing to install or sign up for to start drawing.

Step 2: Export diagrams from Miro

Export the Miro boards you want to keep as images or, where possible, recreate the key diagrams.

Step 3: Rebuild important diagrams

Redraw the diagrams that matter in Excalidraw; the simpler shape set makes this fast for technical content.

Step 4: Set up shared rooms

For collaboration, create end-to-end encrypted shared rooms and share the link with your team.

Step 5: Decide on self-hosting

If internal-data rules require it, deploy the open-source container so diagrams stay entirely in your infrastructure.

Step 6: Keep Miro for workshops if needed

Many teams keep Miro only for facilitated workshops and use Excalidraw for everyday diagrams.

Objection handling: “Is Excalidraw secure enough for internal architecture diagrams?”

For most engineering teams, yes. Shared rooms use end-to-end encryption, so a collaborative sketch is not transmitted in the clear, and the core app is open source, so you can audit exactly what it does. That combination satisfies the majority of internal-diagram security requirements. If your rules are stricter — data must never touch a third-party service at all — the answer is to self-host the open-source container rather than relying on the hosted app, which keeps every diagram inside your own infrastructure. The flexibility to choose hosted-encrypted or fully self-hosted is precisely why security-conscious teams prefer it to a closed SaaS canvas.
