Pros & Cons
CloudSigma
Pros
- CPU, RAM and storage are sized independently rather than in fixed instance types.
- Per-second metering in five-minute billing segments avoids paying for idle hourly blocks.
- A wide certification list covers ISO 27001, 27017 and 27018, SOC 2 and PCI-DSS.
- The white-label model lets telcos and MSPs launch branded cloud services on revenue share, with no licence fees.
- Terraform, Ansible and a REST API with pricing and billing endpoints support automation.
Cons
- No public list prices, so costs require a pricing call.
- Burst usage is charged at higher rates than subscription capacity, which makes bills harder to predict.
- The public review footprint is small, and many reviews are years old.
- The network uptime guarantee does not cover applications, per RFP.wiki.
- Some users report friction during setup and support in edge cases.
Modal
Pros
- GPUs from the T4 up to the B300 are available without quota requests or reservations, and workloads can burst to thousands of containers.
- Per-second billing and scale-to-zero mean idle bursty inference workloads cost nothing.
- Python developers define infrastructure in code and deploy with a single CLI command, with no Kubernetes or Dockerfiles needed.
- The free Starter plan includes $30 a month of compute, and startup and academic credit programs are available.
- Sandboxes support large numbers of concurrent isolated environments for AI agents and untrusted code.
Cons
- Always-on or steady workloads can cost more than reserved GPU rentals from providers such as RunPod or Lambda.
- Containers stay billable for 60 seconds after the last request by default, and keep-warm settings are a common source of bill surprises.
- Region pinning raises prices by 1.15 to 1.75 times, and non-preemptible execution by 3 times.
- SSO, audit logs, and HIPAA support are limited to the custom-priced Enterprise plan.
- Credits from AWS, GCP, or Azure cannot be applied to Modal usage.
