Pros
Agent continues working asynchronously instead of requiring the tab to stay open
Full codebase export avoids vendor lock-in common to closed no-code builders
Bundled Supabase backend removes a separate setup step most app builders leave to the user
Free Forever tier includes unlimited projects, not only a capped trial
GitHub export means a team is not locked into JustCopy's hosting to keep what it built
Pre-wired auth, database, and payment templates skip work that eats time in most app-builder tools
Cons
Young company (founded 2025, 2 employees as of early 2026) with limited operating history
Mobile app-store deployment is locked behind paid tiers, not available on Free
Credit-based limits mean heavier projects can burn through a tier's allowance fast
Token-based pricing makes cost prediction harder than a flat per-seat plan
Founded in 2025, so long-term reliability and support quality are still unproven
Cloning an existing site's UI raises copyright and trademark questions the platform leaves to the user to navigate
