What to watch for on the bill
- Frequent reliability incidents reported by third-party monitors and no clearly advertised uptime SLA on developer tiers
- Widely reported decline in support quality (offshored, multi-day response times, no phone support at standard tiers)
- Per-seat full-product pricing becomes expensive as teams grow (e.g. ~$245/mo for 5 seats on Business)
