Our take
Pick GitHub Copilot if developers already in GitHub who want completions and chat without switching to a separate AI IDE. Pick StackBlitz if front-end engineers who will stay on Personal at $0 (unlimited public projects, 1MB uploads) while they open a first Vitejs IDE, then Pro at $18/month billed annually ($25 monthly) when they need unlimited uploads and localhost / CORS backends — not Teams $55 / $60 per member
