Why Another Tutorial?
In our work and as university teachers, we wanted real code — not notebooks — without the setup friction. We wanted to go beyond “Hello World” examples and understand the production implications: cost, reliability, security, and scale. We needed something our students could open and start experimenting with immediately — no install, no API key drama. And yes, we wanted all of this free and open source. So we built this: every example runs in your browser, every pattern is production-tested, and every concept is explained with code you can modify and break.What Makes This Different
Interactive Sandbox — Code in Your Browser
Every example runs in an embedded sandbox right in your browser via StackBlitz.- No installation required — start coding in seconds
- Multi-provider — OpenAI, Gemini, and Claude — switch with one env variable
- Instant feedback — modify code, run it, see results
- Fork and experiment — break things safely, learn by doing
Beyond the Basics
This isn’t another “Hello World” tutorial. We cover the advanced techniques that make AI systems production-ready:- Prompt caching strategies that significantly reduce costs
- Hybrid search and reranking for RAG systems that return relevant results
- MCP-based agent architecture with multi-server tool discovery
- Evaluation frameworks that catch issues before production
- Security guardrails for PII detection, jailbreak prevention, and output filtering
- Tool design patterns that improve agent accuracy from 58% to 92%
Built for Experimentation
