Most people think building with AI starts with learning to code. It doesn't. It starts with knowing the ecosystem. If you want to build websites, SaaS products, AI tools, automations, agents, or apps using AI, get familiar with these tools first: • GitHub Your project's home. Store code, track changes, collaborate, and connect with hundreds of AI development tools. • GitLab An alternative to GitHub with powerful development and deployment workflows. • Hugging Face The AI model marketplace. Discover, test, compare, and deploy thousands of open source models. • OpenAI Access advanced language, vision, and reasoning models through APIs. • Anthropic Useful for building AI assistants and agent-based workflows. • Google AI Studio Experiment with Gemini models and build AI-powered applications. • Vercel The easiest way to deploy modern websites and AI applications. • Netlify Simple hosting and deployment for web projects. • Supabase Open source backend solution with database, authentication, storage, and APIs. • Firebase Google's backend platform for authentication, databases, analytics, and hosting. • Docker Package your application so it runs the same everywhere. • Postman Test APIs before connecting them to your applications. • Figma Design interfaces before building them. • n8n Create AI automations and workflows without heavy coding • LangChain Build AI agents that can reason, use tools, and work with external data. • Cursor An AI-first code editor that dramatically speeds up development. • VS Code The most popular development environment with a massive ecosystem. • Cloud Platforms AWS, Google Cloud, and Azure help you scale from a prototype to millions of users. The future belongs to builders who can connect tools, models, data, and workflows together. You do not need to master everything. Learn what each tool does. Learn how they connect. Then start building. The best way to learn AI is not another course. It's shipping projects.
