What is Grass Lemon?
Grass Lemon is an AI brand kit generator aimed at vibe coders and indie makers. Starting from a project's name, one-liner, audience, tone and theme colors, it produces AI logo marks and then packages them into favicons, OG images, web app manifests, metadata and framework-ready snippets, so a new app gets a consistent set of launch assets in one pass.
The workflow reads app metadata and existing assets, generates several logo directions through KIE AI using GPT Image 2 with no-text and no-stock-icon constraints, scores candidates for brand fit and small-size clarity, then removes backgrounds and creates SVG variants. Unlike tools that only resize an existing image, it focuses on creating the mark first. It is available on the web and as an open-source CLI and skill that can run locally with your own KIE key.
Who it's for
- Vibe coders shipping side projects
- Indie hackers launching multiple apps
- Developers using AI coding agents
- Template makers and small studios
- Freelancers building client prototypes

Grass Lemon key features
AI logo maker for distinctive marks
Generates irregular, startup-style logo marks from project context rather than relying on initials or icon packs.
Favicon generator with size previews
Previews each candidate at 16, 32 and 48 pixels so weak marks are caught before a direction is chosen.
OG image generator
Builds share images from the selected mark, app name, one-liner and the project's exact colors.
Framework-ready snippets
Exports HTML head tags plus integration snippets for Next, Vite, TanStack, Astro and Nuxt, along with manifests and metadata.
AI quality review and vectorizing
Scores candidates for brand fit, silhouette, color accuracy and vector readiness, then removes backgrounds and produces SVG variants.
CLI for AI coding tools
Installs with an npx command and runs the same workflow inside tools such as Claude Code, Cursor, Codex, GitHub Copilot and Windsurf, with a local BYOK option.
Grass Lemon use cases
Brand assets for vibe coders
Give a weekend project a logo, favicon and share card before launch without opening a design suite.
Shipping many experiments
Indie makers who launch several apps can reuse one workflow instead of repeating asset setup each time.
Local client work
Freelancers can run the CLI locally with their own provider key to keep client projects on their machine.
Finishing framework integration
Drop generated head tags, manifests and framework snippets straight into a Next, Vite, TanStack, Astro or Nuxt app.
