anthropics/claude-quickstarts

Claude Quickstarts is an official collection of ready-to-run example projects from Anthropic, the company behind the Claude AI. Each project is designed to give developers a working starting point for building real applications using the Claude API, so they can skip the blank-page problem and get something running quickly. To use any of the projects, you need a Claude API key, which you can get for free at Anthropic's developer console. The collection includes several distinct demos: a customer support agent that uses Claude to answer questions from a knowledge base; a financial data analyst that lets you explore financial data through a chat interface with interactive visualizations; a computer use demo that shows Claude controlling a desktop computer directly; a computer use best-practices reference that demonstrates patterns like prompt caching, batched tool calls, and image pruning for building more reliable and cost-effective computer-control agents; a browser automation demo where Claude navigates websites, reads page content, and fills forms using a custom browser tool; and an autonomous coding agent that can build complete applications across multiple sessions, tracking progress through git. Each project lives in its own folder with its own setup instructions. The general pattern is: clone the repository, go into the relevant folder, install dependencies, set your API key as an environment variable, and run. The project is written primarily in Python, licensed under MIT, and welcomes community contributions. For developers who want to dig deeper, Anthropic links to their API documentation, a cookbooks collection, and a fundamentals course from the same readme.
