How this category is scored

Every platform here is scored against the same five components. The Expert Assessment component uses a rubric written specifically for app hosting & paas.

Developer Experience
How quickly a competent engineer gets to production.
Reliability
Uptime record, incident history and how failures are communicated.
Performance
Latency, throughput and behaviour under load.
Pricing & Predictability
Cost at real usage, and whether the bill can surprise you.
Ecosystem & Portability
Integrations, standards, and how hard it is to leave.
Security & Compliance
Access control, certifications and data handling.
Support
Response quality when production is broken.
