Cloudflare

Pros

• The free plan includes unmetered DDoS protection, a CDN, a WAF and universal SSL.
• R2 object storage charges no egress fees.
• Workers has very low entry pricing: a $5 monthly minimum and $0.30 per additional million requests.
• The Business plan adds a 100 percent uptime SLA and PCI DSS compliance for $200 a month billed annually.

Cons

• Reviewers report slow support on Free and Pro, which have no chat or phone support.
• Global outages in November and December 2025 disrupted many sites at the same time.
• Reviewers report billing problems, such as charges after cancelling add-ons.
• It offers no traditional shared hosting, VPS or dedicated servers, so you still need an origin host for conventional workloads.

Fluidstack

Pros

• Can build and deliver capacity at gigawatt scale, which is why Anthropic chose it for its Texas and New York data centers.
• Runs managed Slurm and Kubernetes on bare metal, so training teams do not have to operate the cluster themselves.
• SemiAnalysis gave its GPU clusters a ClusterMAX Gold rating.
• Heavily funded, including an $830M Series A in January 2026, which lowers the risk that the supplier fails.

Cons

• There is no public rate card or self-serve signup, so pricing requires a sales quote.
• Public documentation on APIs, storage and compliance certifications is scarce.
• Third-party sources say its GPU catalog is narrower than marketplace providers and that on-demand billing is per hour.
• It offers no general web hosting, managed databases or app platform services.
