Worth it if you actually build things
Been using it daily for 4 months across 6 shipped projects. The main win is speed — I stop debating and start building. When it breaks I usually find the answer in Discord in under 15 min.
Pros
- Fast iteration loop — feedback in seconds
- Handles edge cases without hand-holding
Cons
- Occasional outages during peak hours
