| Minimum commitment | None on pay-as-you-go | $5 minimum to start |
| Payment model | Prepaid balance; no automatic top-up | Prepaid credits; optional auto top-up |
| Egress | not stated | Priced per byte by each host |
| Regions | not stated | 40+ data centres worldwide |
Neither site tells you whether your data trains their models, an uptime SLA, whether you get credits when it breaks or how long you have to dispute a bill. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.
