What it does

Libretto is a toolkit for building reliable browser automations using AI and TypeScript, allowing startup founders to automate repetitive browser tasks

When to use it
  • When you need to automate data extraction from websites
  • When you want to automate tasks on web applications
  • When you need to integrate browser automation with other AI-powered tools
Ready-to-paste prompt
const { Browser } = require('@libretto/core'); const browser = new Browser(); browser.navigateTo('https://example.com'); browser.click('button', { selector: 'text=Click me' });
Heads up: You need to have Node.js version 16 or higher installed to use libretto, as it relies on TypeScript and modern JavaScript features
