Blaxel
Blaxel provides isolated microVM sandboxes that boot in milliseconds, persist memory and filesystem state, auto-suspend to zero compute cost when idle, resume in ~25ms, offer persistent storage and networking controls, and a Batch API to spawn many sandboxes for parallel tasks.
Blaxel documents a Pay-as-you-go usage model with per-second compute and per-GB storage rates, up to $200 in free credits, and tier-based quotas that scale with top-ups.Is Blaxel right for you?
Good for
- Teams building many stateful autonomous agents that need fast-resume microVMs, per-second usage billing, and fine-grained outbound networking and model routing controls.
- MicroVM sandboxes resume from standby in ~25 milliseconds, preserving memory and filesystem state for instant continuation.
- Idle sandboxes scale to zero compute cost; you only pay snapshot storage while suspended.
Keep in mind
- Agent Runtime is documented as 'Soon' and 'coming soon', so availability and rates for session-first long-running agents are not yet established.
- Long background work beyond sandbox durations relies on Batch API which runs up to 24 hours; longer runtimes require alternative arrangements.
- Buyers who expect session-first long-running Agent Runtime availability without confirming Agent Runtime launch timing and capabilities—verify Agent Runtime availability for long-lived session needs.

Documented strengths
MicroVM sandboxes resume from standby in ~25 milliseconds, preserving memory and filesystem state for instant continuation.
Idle sandboxes scale to zero compute cost; you only pay snapshot storage while suspended.
Networking features include outbound allow-lists, static IPs, proxy routing with secret injection, and a model gateway for routing calls.
Limitations to consider
Agent Runtime is documented as 'Soon' and 'coming soon', so availability and rates for session-first long-running agents are not yet established.
Long background work beyond sandbox durations relies on Batch API which runs up to 24 hours; longer runtimes require alternative arrangements.
Choosing a plan
Confirm Agent Runtime availability and the maximum continuous runtime per workload (versus Batch API limits) with Blaxel before relying on long-lived agent sessions.
