Frequently asked questions
Does SaaS Starter Kit work with Cursor and Claude Code?
Yes. This kit ships with a pre-written .cursorrules file tuned specifically for this codebase. Open it in Cursor and the AI already knows the architecture, naming conventions, and component patterns from message one. It also works with Claude Code, Windsurf, and any LLM-powered editor.
What's inside the .cursorrules file?
The .cursorrules file documents the full project architecture, file structure, naming conventions, auth flow, payment integration, and component contracts. It also includes AGENTS.md, DESIGN_SYSTEM.md, and COMPONENTS.md for complete AI context.
What is included in SaaS Starter Kit?
Full source code, documentation, and a production-ready nextjs, typescript, tailwindcss, supabase setup. One-time purchase of $149 with lifetime access to all future updates.
Can I use this for commercial projects?
Yes, every kit on VibecoderSupply comes with a commercial licence. You can use it for client projects, SaaS products, or any commercial application. No attribution required. One purchase covers unlimited projects.
How is this different from free boilerplates on GitHub?
Free boilerplates give you a starting point but leave you to figure out architecture, auth, payments, and AI integration yourself. This kit ships production-ready with nextjs, typescript, tailwindcss, supabase, plus .cursorrules and full documentation so your AI coding assistant understands the entire codebase immediately.
