Solid, with rough edges
Good defaults, sensible primitives, opinionated in the right ways. Would recommend to any founder who wants to ship this quarter, not next.
Pros
- Fast iteration loop — feedback in seconds
- Handles edge cases without hand-holding
Cons
- Occasional outages during peak hours
Gotcha: Free tier throttles on weekends. Not documented.
