Generate brand kits from your terminal

The three things it does

No command zoo. The CLI exists to get launch-ready brand assets into a codebase.

Generate mark candidates

Create distinctive logo marks from your project brief and theme colors.

Review favicon clarity

Check the mark where it matters: tiny browser tab sizes.

Apply to your repo

Write the favicon, OG image, logo files, and framework snippets into place.

Install with npx, then let your agent run it

Use a Grass Lemon API key for hosted credits. The CLI configures your agent to call the same brand-kit API as the web app.

Install
npx grass-lemon@latest init
pnpm / yarn / bun
pnpm dlx grass-lemon@latest init
yarn dlx grass-lemon@latest init
bunx grass-lemon@latest init

From brief to applied assets

The workflow stays short on purpose.

1

Brief and detect

The agent reads the project name, product context, existing assets, and theme colors.

Output: a focused brand brief the image model can actually follow.
2

Generate and review

It generates a small set of candidates and rejects marks that fail at favicon size.

Output: a chosen mark with a clear silhouette at 16px.
3

Export and apply

It exports the web assets and applies the files and snippets to your app.

Output: favicon files, logo files, OG image, manifest, and framework snippets.

Bring your own key and ship a brand kit locally

Start with an API key, then run the same workflow from your coding agent.
