Courses & bootcamps

Structured training on agentic development and Claude Code on platforms like Udemy or courses by specialized creators. Useful if you prefer a guided path over exploring docs.

If you prefer a guided path over exploring documentation, here's what the market offers:

  • Udemy / Coursera: €10-60 courses on Claude Code, agents and prompt engineering. Look for ones updated within the last 3 months — the ecosystem moves fast.
  • Specialized creator courses: top developers in the niche sell €50-300 trainings with real projects, private community and lifetime updates.
  • Anthropic Academy (free): before paying for anything, check Anthropic's official free courses — they cover the essentials with excellent quality.

Tip: only pay for what you can't learn for free: mentorship, community and guided projects. The theory is already in the docs.

Premium templates & boilerplates

Paid starters (full SaaS, AI-integrated apps) optimized for working with Claude Code: agent-friendly structure, CLAUDE.md included and CI configured.

A premium boilerplate saves you weeks of setup. The good ones include:

  • A pre-written CLAUDE.md: the context file that makes Claude Code understand the project from the very first prompt.
  • Full stack: authentication, payments (Stripe), database and deployment configured and tested.
  • Agent-friendly structure: code organized so agents can navigate and modify it without breaking anything.

Where to find them: Gumroad and Lemon Squeezy host most of them (€30-200). Always check recent reviews and that they offer updates.

Ecosystem SaaS tools

Usage dashboards, visual agent orchestrators and marketplaces with free and paid tiers. The management layer when you go from hobby to production.

Once you go from experimenting to relying on AI daily, these tool categories become essential:

  • Usage & cost dashboards: monitor how many tokens you consume, on which projects and what each task costs.
  • Visual orchestrators: interfaces to launch and supervise several agents in parallel without living in the terminal.
  • Skill & plugin marketplaces: rated catalogs to discover and install verified resources.

Tip: almost all have a free tier that's enough for personal use — start there and pay only when the limit truly bothers you. The most complete directory to discover them is the applications section of awesome-claude-code.

How to evaluate a repo before installing it

  • Activity: recent commits? answered issues? The ecosystem moves fast and a repo abandoned 8 months ago may be obsolete.
  • Security: read what the code does before granting permissions, especially hooks and MCP servers that execute commands.
  • License: MIT and Apache 2.0 allow commercial use; other licenses may not.
  • Stars ≠ quality: use them as a signal, but test for yourself. Many gems still have few stars.
