A person must first deploy it on a Linux x86_64 host with KVM and Kubernetes. Version 0.8.0 has no tagged release, changelog or public container images.\n\n**Sprites.** A Sprite keeps a 100 GB ext4 disk between runs, bills compute only while active and can be checkpointed and restored through a published OpenAPI contract. The status page records four Sprites incidents in the last 90 days, one lasting over seven hours, and outbound network access is unrestricted until a policy is set.\n\n## Before you call either\n\n### SPACE\n\n1. Ask your operator for the API base URL (before `/v1`, or `/api/v1` on shared hosts), the data-plane URL and a bearer token before planning any call\n2. Poll the returned operation until it succeeds and the sandbox is `running` before creating a command. A 202 response is not readiness\n3. Attach to the command's events URL with its session token to start the process, decode base64 output, and treat only `process_exited` as completion\n4. Send an `Idempotency-Key` on creates, lifecycle calls and commands, and retry only when `retryable` is true, after any `Retry-After`\n5. Save output as it arrives. Reconnecting with `Last-Event-ID` returns `resync_required`, not the missed output\n\n### Sprites\n\n1. Create a token at sprites.dev/account after a browser signup, and send it as `Authorization: Bearer \u003ctoken\u003e` to `https://api.sprites.dev`\n2. Follow the OpenAPI document, not the product page example. Create with `POST /v1/sprites` and a JSON `name`, and run commands with `POST /v1/sprites/{name}/exec` using `cmd` query parameters\n3. Set a network policy with `POST /v1/sprites/{name}/policy/network` before running untrusted code. Egress is open until one is set\n4. Processes started by exec stop on a cold wake. Define a Service for anything that must answer the request that wakes the Sprite\n5. Create a checkpoint before a restore. Restoring replaces the filesystem, ends active sessions and keeps no copy of the replaced state\n6. Sprite creation is limited to 10 a minute on pay-as-you-go. The Go SDK reads `Retry-After` and the error code `sprite_creation_rate_limited` on a 429\n7. Delete Sprites you no longer need. An idle Sprite still bills cold storage for the bytes it holds\n\n## Questions\n\n### Which is better for AI agents, SPACE or Sprites?\n\nSprites scores 58.3 (C) on agent readiness against SPACE's 56.2 (C), and leads in 3 of 7 scored categories. SPACE leads on security \u0026 auth, payments \u0026 pricing and transparency \u0026 trust.\n\n### Do SPACE and Sprites need an API key?\n\nSPACE takes an API key or an OAuth sign-in. Sprites needs an API key.\n\n### Can an agent call SPACE and Sprites without installing anything?\n\nNo hosted endpoint is listed for SPACE. No hosted endpoint is listed for Sprites.\n\n### Are SPACE and Sprites open source?\n\nSPACE is open source (Apache-2.0). No open-source release is listed for Sprites.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/perplexity-space-vs-sprites.json, and with the fewest tokens: https://www.anchorterminal.com/compare/perplexity-space-vs-sprites.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"perplexity-space\", \"b\": \"sprites\"}`.
