Perplexity SPACE
https://github.com/perplexityai/SPACE
SPACE is Perplexity's open-source platform for running agent and user code in isolated Firecracker microVMs. Applications use its HTTP API to create Linux environments, execute commands, collect output, and manage sandbox lifecycles.
| Pricing model | No public SPACE billing model documented. |
|---|---|
| Pricing The headline compute price as the provider states it. Sorting ranks prices stated per vCPU over time, converted to hourly. Other pricing models sort after, unranked. | No public SPACE compute rate listed. |
| Free while idle Whether a stopped, paused, or sleeping sandbox costs nothing. | – |
| Elastic Resources flex with what the sandbox actually uses, and the bill follows: yes when the provider bills on active or observed use, no when capacity is reserved or allocated and billed while it runs. | – |
| Memory snapshots Whether RAM state survives a pause and resume, not just disk. | ✓ |
| Wake on request Whether a stopped sandbox wakes automatically on inbound traffic. | ✓ |
| Start / resume Typical time from create or resume to running. Sorting ranks stated times, converted to seconds; claims with no figure sort after, unranked. | 60 ms median create; 89 ms p90 in reported production measurements—not a cold-boot guarantee. |
| Max runtime The longest a sandbox may run. | – |
| Isolation The isolation technology between sandboxes. | Firecracker microVM |
| GPUs Whether GPU instances are available for sandboxes. | – |
| Docker Whether Docker containers can run inside the sandbox. | – |
| SDKs | – |
✓ yes · ✕ no · – no cited public fact.
Automatic waking on ingress is subject to authorization and the sandbox's access-wake policy.
