All commands on this page require a real secret API key (21st_sk_…) from Settings → API keys. A 21st login session token is not enough. Pass it with --api-key, or set API_KEY_21ST.

​
Publish a component

21st publish ./Component.tsx --description "A responsive pricing table"
The CLI auto-detects the component name, slug, and tags from the source, and finds or synthesizes a demo file. Common flags:

--tags a,b,cSet tags explicitly

--public / --unlisted / --privateVisibility (default unlisted; --public goes through moderation)

See Publishing → Quick Start for the full flow and requirements.

​
Publish a theme

21st publish-theme ./theme.css --name "Midnight" --tags dark,minimal
The CSS file must contain both :root and .dark blocks.

​
Publish a template

21st publish-template "My SaaS starter" \
  --site https://demo.example.com \
  --preview ./preview.png \
  --price 49 \
  --buy-url https://gumroad.com/l/my-starter \
  --description "A full Next.js SaaS starter" \
  --video https://youtu.be/xyz \
  --tags 12,45
Submits a template listing for moderation (it lands as a draft). For paid templates, set --price and a --buy-url checkout link. See Selling & promotion.

​
Edit your content

21st edit <id|slug> --type component --visibility unlisted
21st edit <id|slug> --type theme --name "New name" --tags a,b
--type is component, theme, or template. Editable fields differ per type (templates use numeric tag ids and have no visibility field).

​
Unpublish or delete

21st delete <id|slug> --type component --yes
--yes is required to confirm. For components and themes this unpublishes (sets visibility to private / clears the published date). For templates it is a permanent delete.
