The Reality Check
Here's what the marketing materials won't tell you:
xpander.ai is promising but new—expect some rough edges and limited community resources.
Clarifai works well but gets expensive quickly. Budget accordingly for production use.
Replit is fantastic for collaboration but you'll eventually need local development for serious projects.
Supabase has great developer experience but requires PostgreSQL knowledge for advanced features.
TensorFlow remains powerful but PyTorch is often easier for research and experimentation.
GitHub Copilot boosts productivity but can create over-dependence on AI suggestions.
