Not ideal for
Projects requiring non-Next.js technology stacks, users needing native mobile app development, or teams looking for Windows-native desktop applications.
Massvai is a highly capable choice for shipping full-stack SaaS MVPs because it prioritizes standard industry tech stacks and codebase ownership, effectively avoiding the platform lock-in common with other AI builders.
