From Idea to Shipped in 20 Hours: How a Solo Founder Builds Production-Ready SaaS, Marketplaces & Online Shops with Claude (Paperback) (ISBN-13: 9798196618710)

70 hours, solo, no team. That's what it took me to ship a production-ready SaaS to live users. With the workflow and stack in this book, you can ship in 35-40 hours - and the 20-hour path is real with the optional templates and boilerplate (sold separately).

This book covers the part most guides never reach: what keeps the product alive after you ship.

This is the unvarnished documentation of a real build. Every lesson comes from a live project. Every hour count is real.

• A No-Hardcoding standards discipline - single-source patterns, pre-edit hooks, a verify-gate, and a "ratchet" for legacy debt, with a real audit of the boilerplate as the worked example.
• API and MCP infrastructure - a tier-based public API and an AI-agent-ready MCP server, taught as architecture so AI agents can discover and use your product.
• The four-tier gating model - free / registered / pro / elite, server guard plus UI hook reading one source of truth.
• More production patterns - append-only audit logs, geo-block region-pinning, upstream-license audits, content embeds.
• Building EU-sovereign - a full migration roadmap to European providers with honest trade-offs per building block.

Classic SaaS, marketplaces, content platforms, community products, digital shops, booking systems, business tools. The architecture is the same: users register, pay for access, get different features by plan. EU-compliant. Automated emails. Admin dashboard. Multiple auth methods. Cron jobs.

Three AI tools, three roles: Claude Chat for strategy, Claude Code for implementation, v0.dev for design. This book shows how they work together - the separation that makes solo development viable at production quality.

Stack decisions, authentication (with the WebView-OAuth trap), Stripe payments and EU right-of-withdrawal, email with Resend, the GDPR checklist, deployment, analytics without cookie-banner drama - plus chapters on standards, API/MCP, gating, production patterns, and EU sovereignty.

You have a product idea and want to ship it - and keep it maintainable, discoverable, and defensible as it grows. You're comfortable with AI tools but want to understand what's happening. You don't need to be a senior engineer; you should be willing to use the command line and Git.

The complete path - from idea to launch, and from launch to a SaaS that sustains itself.

Today is the best time to start. The second best is right after you finish this book.
