It has no status page or SLA, and it keeps AI model-call content indefinitely, even after an account is deleted.\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### Maritime\n\n1. Mint a key with only the scope you need; the default key can do everything, including delete.\n2. Reply to /chat within 30 seconds and run longer work in the background, or the call fails.\n3. Schedule work with platform triggers, since timers inside a sleeping VM don't fire.\n4. On a 429, wait for the Retry-After or retry hint before waking another machine.\n5. Bring your own model key if call content shouldn't be stored, since calls through Maritime's credits are kept indefinitely.\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, Maritime or Sprites?\n\nMaritime scores 66.5 (B) on agent readiness against Sprites's 58.3 (C), and leads in 4 of 7 scored categories. Sprites leads on reliability.\n\n### Do Maritime and Sprites need an API key?\n\nBoth need an API key.\n\n### Can an agent call Maritime and Sprites without installing anything?\n\nMaritime has a hosted endpoint at https://mcp.maritime.sh/mcp. No hosted endpoint is listed for Sprites.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/maritime-vs-sprites.json, and with the fewest tokens: https://www.anchorterminal.com/compare/maritime-vs-sprites.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"maritime\", \"b\": \"sprites\"}`.
