What is unpkg.ai?
unpkg.ai is an AI-powered ESM module generation service. You describe a function in a URL, such as formatCurrency(amount:number,currency?:string):string, and the service uses an LLM to produce a JavaScript module that you import directly with a standard import statement from an https://unpkg.ai/esm/ address.
The workflow is intentionally minimal: there is no signup, no API key and no authentication. The homepage shows examples for a currency formatter, a tip calculator with bill splitting, a password generator, a color palette generator, a minesweeper game, a rich text editor and a dashboard with a line chart. Optional parameters let you choose the underlying model (for example gpt-4 or claude-3) and a random seed for more deterministic output.
Key features
- On-demand ESM module generation from a URL-encoded function signature
- No signup, API keys or authentication required
- Optional model selection (e.g. gpt-4, claude-3)
- Optional seed parameter for deterministic output
- Ready-to-import modules for utilities, UI components and small games
Who is it for
- Frontend and JavaScript developers

- Developers experimenting with top-down, prompt-driven coding
Pros and cons
- Zero setup: a single import statement is enough
- Works with standard ES module imports in the browser
