Excalidraw CLI

Manage your Excalidraw+ workspace from the terminal, and render any .excalidraw file to PNG. Rendering runs locally and needs no account.

$ excalidraw scenes list --limit 3 -o table
ID                    NAME                 COLLECTION            PINNED  UPDATED

Output is JSON by default, so it works with jq, shell scripts and AI agents.

Install

npm install -g @excalidraw/cli

Or try it without installing: npx @excalidraw/cli --help. Requires Node.js 22 or newer.

To update, run excalidraw update. It installs the latest version with the package manager you installed the CLI with: npm, pnpm, yarn, bun or Volta. excalidraw update --check only reports whether a newer version is out.

Commands you run in a terminal check for a newer version at most once a day, while the command runs, and mention it after the output. Set EXCALIDRAW_NO_UPDATE_NOTIFIER=1 to turn this off.

Quick start

Workspace commands need an Excalidraw+ API key. The authentication docs explain how to create one.

# Paste your API key once; later commands use it
excalidraw login

# Check which workspace the key belongs to
excalidraw whoami

# Create a collection, then a scene in it from a local file
excalidraw collections create --name "Product diagrams"
excalidraw scenes create --name "Architecture" --collection-id <collectionId> --file drawing.excalidraw

# Save a scene's content, or render it straight to PNG
excalidraw scenes content get <sceneId> --out scene.json
excalidraw scenes render <sceneId> --out scene.png

Every command has --help with examples, for instance excalidraw scenes content patch --help.

Render to PNG

render turns a local file into a PNG, no API key needed. scenes render does the same for a scene in your workspace.

excalidraw render drawing.excalidraw --out drawing.png
cat drawing.excalidraw | excalidraw render - --out drawing.png
excalidraw scenes render <sceneId> --frame-id <frameId> --out frame.png

With a file path, the command prints the PNG's path and dimensions as JSON. Pass --out - to write the PNG to stdout instead, for example to pipe it into another program:

node generate-scene.js | excalidraw render - --out - > drawing.png
excalidraw scenes render <sceneId> --out - | magick png:- -resize 50% preview.png

Rendering uses a browser that's already installed: Chrome, Edge or Chromium, or Firefox (slower) if none of those is. The CLI doesn't download one. If it can't find yours, pass --browser-path or set EXCALIDRAW_BROWSER_PATH.

Option	Default	Notes
--out <file>	required	File path, or - for stdout.
--frame-id <id>		Render just this frame.
--scale <n>	1	Resolution multiplier, up to 16.
--max-width, --max-height	2048	Size limits in pixels, up to 16384. Raise them along with --scale.
--padding <px>	20	Ignored for frames.
--theme <light|dark>	scene setting
--transparent	off	Transparent background.
--timeout <ms>	30000	How long a render may take.

• Images must be embedded in the file. Image URLs and website embeds aren't loaded.
• The output keeps the scene's aspect ratio and stays under 64 megapixels.
• Chinese, Japanese and Korean text in the hand-drawn font needs a font that's downloaded the first time a scene uses it, then cached. Without network access, that text uses a system font. --fonts-url sets other download locations, or none to turn downloads off.
• Emoji come from your system's fonts.

Commands

Command	What it does
login	Check an API key and save it for later commands
logout	Remove the saved API key
whoami	Show the workspace, key type, credential source and API origin in use
scenes	List, create, rename, move, pin and trash scenes
scenes content	Read, replace or patch a scene's drawing
scenes render	Render a workspace scene to PNG
render	Render a local file to PNG
collections	Manage collections and the scenes in them
workspace	Read or update the workspace name and picture
workspace users	List, update or remove members
workspace invites	Manage email invites and invite links
logs	Query the workspace audit log
update	Update the CLI to the latest version

Updating the workspace, and the users, invites and logs commands, need admin rights. A personal key that belongs to a member gets HTTP 403.

Editing scene content

scenes content put replaces the whole scene with your file, so elements missing from the file are removed. Use it when the file is the source of truth. The file only needs elements; missing fields such as version and appState are filled in.

scenes content patch merges a partial payload into the stored scene:

• Elements merge by ID, and the higher version wins. Send an element with isDeleted: true to remove it.
• Files are added or replaced by ID.
• From appState, only viewBackgroundColor and lockedMultiSelections are stored.

echo '{"appState":{"viewBackgroundColor":"#f8f9fa"}}' | excalidraw scenes content patch <sceneId> --file -

scenes create --file creates a scene and fills it in one step, from a full export or a partial payload like the one above. An invalid file is rejected before the scene is created. If writing the content fails afterwards, the error names the new scene so you can retry.

Scripting and agents

• Commands print JSON, except login and logout, which print a confirmation. -o table prints list commands, whoami and update as a table.
• Set EXCALIDRAW_API_KEY rather than running login, which asks for the key in a terminal. excalidraw login --api-key <key> saves a key without asking.
• Lists return 5 items by default (50 for logs), up to 100 with --limit. --all fetches every page.
• --raw prints the API's response text as received, and shows API errors in full.
• - as a file path reads from stdin for inputs (render -, --file -) and writes to stdout for --out.
• Rate-limited and failed read requests are retried, see --retries and --request-timeout. Retry notices go to stderr, so stdout stays parseable.
• Any error exits with status 1.
• The update check only runs when stdout and stderr are both a terminal, and never in CI (CI set), so it doesn't touch piped output or slow down scripts.

Configuration

These flags can also be set with environment variables.

Flag	Environment variable	Default
--api-key	EXCALIDRAW_API_KEY	key saved by login
--api-url	EXCALIDRAW_API_URL	https://api.excalidraw.com
-o, --output	EXCALIDRAW_OUTPUT	json
--retries	EXCALIDRAW_RETRIES	3
--request-timeout	EXCALIDRAW_REQUEST_TIMEOUT	60000 ms
--browser-path	EXCALIDRAW_BROWSER_PATH	detected
--fonts-url	EXCALIDRAW_FONTS_URL	Excalidraw's CDN

For a self-hosted or staging instance, set --api-url to the origin, without /api/v1.

API keys

There are two kinds of API key. Workspace keys act for the whole workspace. They can't see private scenes, so scenes create needs a real collection ID. Personal keys start with uk- and act as one user, with that user's role. They can pass private as the collection ID to use the owner's private collection. Run excalidraw whoami to see which kind you're using.

excalidraw login asks how to sign in (an API key for now; OAuth is coming), checks the key against the API and saves it. A key the API rejects isn't saved. Commands use the saved key when neither --api-key nor EXCALIDRAW_API_KEY is set; whoami reports which one is in use as credentialSource (flag, env or login).

Keys are saved per API origin, so a staging key is only sent to staging: excalidraw login --api-url https://staging.example.com saves one next to your production key. They live in ~/.config/excalidraw-cli/credentials.json ($XDG_CONFIG_HOME if set, %APPDATA% on Windows), readable only by you. excalidraw logout removes the key for the origin; to revoke the key itself, delete it in Excalidraw+.

The full API reference lives at plus.excalidraw.com/docs/api.
