Teams can select from marketplace templates—such as SaaS starters, CRMs, portals, and ecommerce kits—to accelerate development and avoid boilerplate work. Pricing is intentionally simple: pay only for AI calls, VM uptime, and optional template licenses. Collaboration tools, audit history, and refundable “bad-AI” edits keep projects controlled and safe. With CI/CD, branch management, and VS Code support already wired in, AppWizzy works like a modern engineering workflow powered by AI. The result is a fast, efficient, and production-grade way to build apps that can scale for years.
