A few that need qualification
These providers publish a plan or usage price, but it doesn’t establish the same always-on machine.
| Provider | Published price | What remains unverified | Evidence |
|---|---|---|---|
| Unikraft Cloud | $0 Hobby plan 2 running instances, 2 total vCPU, 4 GiB total RAM | The current page advertises enough resources for the example, but does not clearly establish a 720-hour compute allowance or all storage/usage charges. Treat $0 as the advertised plan fee, not a verified free always-on invoice. | Official pricing |
| Kernel (hosted) | $172.80 usage / shared $5 credit 4-GB app invocation equivalent | 2,592,000 seconds × $0.0000666668/sec, with a $5 Developer credit applied once per account. This is a hosted invocation meter, not a quoted 2-GB always-on VM. Browser usage is billed separately. Hypeman below is a different, self-hosted product. | Official rates & allocation |
Self-hosted tools and infrastructure
These do not have a comparable hosted 2-GB sandbox price. You must buy the host first; dividing its RAM by 2 GB does not guarantee enough CPU, disk, or isolation overhead for that many fully busy guests.
- SlicerVM + Latitude.sh: orchestration software plus a separately billed host. Total = the chosen Latitude server + Slicer licence + storage/network costs.
- Hypeman: self-hosted VM manager, not Kernel hosted browser pricing. Total depends on your physical or nested-virtualization host.
- celld: local runtime software; host infrastructure is separate.
- AWS EC2, Azure VMSS, Google Compute Engine, Hetzner, Latitude, Scaleway and Vultr: these are underlying host infrastructure options. A 2-GB VM quote would price a different product from the larger KVM-capable hosts used in those studies. Host region, SKU, CPU class, disk and guest density must be specified to calculate cost per sandbox.
Checked against official pricing pages. Calculations use unrounded rates; totals are rounded to cents. Account allowances apply once, not once per VM. This estimates infrastructure usage; commercial quotas and continuous-runtime eligibility still apply.
