Pros & Cons
Nebius
Pros
- Newest NVIDIA hardware, including B300 and GB300 NVL72, is listed with published per-hour prices.
- Network egress, ingress and public IPs are free, which removes a common hidden cost on hyperscalers.
- The certification list is broad: SOC 2 Type II, SOC 3, several ISO standards including 27001 and 42001, and CSA STAR.
- EU data centers in Finland and Paris help with GDPR and data residency.
- Infrastructure as code is fully supported through a CLI, a Terraform provider, gRPC and REST APIs, and SDKs.
Cons
- The catalogue is narrow outside AI. The only managed database is PostgreSQL, and there is no CDN or web hosting.
- Some users report slower support responses than AWS or CoreWeave.
- Users note documentation gaps for advanced setups.
- Kubernetes and Slurm workflows assume DevOps expertise.
- Commitment pricing and the largest clusters require contacting sales.
Vast.ai
Pros
- Marketplace rates for H100 and RTX 4090 run well below RunPod, Lambda, and AWS in mid-2026 reviews
- Per-second billing with no contracts or minimum hours
- Wide hardware choice across 68+ GPU types and 40+ data centers
- Secure Cloud filter limits results to vetted ISO 27001 data center hosts
Cons
- Reliability varies by host, and reviewers report disconnections
- No platform uptime SLA on standard marketplace instances
- Reviewers describe support as limited and inconsistent
- Storage is billed while instances are stopped, and bandwidth costs extra, which raises the real cost
