| Free tier | 'Up to $200 in free credits' on the pay-as-you-go plan, with 'Tier 0 | Free | 10' concurrent sandboxes. The page does not say what 'up to' depends on, and no expiry is stated. unit mixed; metered on wall-clock; Credits are topped up to raise the tier; the free grant is bounded by a qualifier the page never explains. |
|---|---|
| Price | none stated |
| Per-object cap | No per-sandbox vCPU or memory cap is published on the pricing page; the Custom plan advertises 'Up to 256 GB RAM per sandbox or job' as an upgrade over pay-as-you-go. |
| Retention | Sandboxes sit 'on automatic standby' with memory and filesystem snapshotted; Tier 0 and Tier 1 'enforce expiration dates (Tier 0 and 1, with respectively up to 7 and 30 days)'. In higher tiers unlimited persistence is permitted. (7 days) |
| Egress | No egress charge is listed; outbound traffic can be constrained by a per-domain firewall and a proxy, which is a policy control rather than a meter. |
| Identity | email Signup is 'Start for free' with no card shown on the pricing page; no hold is mentioned. Raising the tier requires a top-up, which introduces a card at that point. |
| Limits |
Every sandbox scales to zero after inactivity whether or not an expiry policy is set, so 'running' is not a state Blaxel holds by default. |
| Binding | retention-clamped A 7-day maximum existence beats the credit: USD 200 cannot buy a month because no single sandbox is allowed to live that long at Tier 0. |
| Interface | unknown |
| Tooling | not stated |
| Composes with | not stated |
| Reliability | 'Automatic scale-to-zero after 5s inactivity' means a process with no client connection is suspended unless keep-alive is arranged; the docs offer process keep-alive as the workaround. |
| Notes | Blaxel prices CPU inside the RAM rate: USD 0.0000115 per GB of RAM per second is USD 0.0414 per GB-hour, so a 1 GB sandbox is USD 0.0414 an hour and USD 200 would be 4,831 hours, or a 4 GB sandbox USD 0.1656 an hour and 1,208 hours. Neither number is reachable as a month of uptime because of the 7-day Tier 0 expiry and the 5-second standby. The borrow against it: it is the cheapest per GB-hour of the sandbox providers here, and the right tool for bursty agent work. |
| Evidence rung | documented The credit, the rates and the tier-0 expiry are first-party. What is not established: whether a keep-alive process suspends the 5-second standby timer in practice, and whether Tier 0 counts the 7-day limit from creation or from last wake. |
