No REST API, and the JavaScript and Go SDKs are beta.\n\n**Morph Cloud.** Pause and snapshot keep memory and running processes, and one call branches an instance into several copies. A public OpenAPI file covers 69 operations. No terms of service, privacy policy or security page was found, the free plan includes no compute credit, and the changelog holds one entry from November 2024.\n\n## Before you call either\n\n### Modal Sandboxes\n\n1. Pass `timeout=` when you create a sandbox. The default lifetime is 5 minutes\n2. Set `block_network=True` or a `cidr_allowlist` for untrusted code\n3. Give a sandbox a `name` so a retried create raises `AlreadyExistsError` instead of starting a second one\n4. Snapshot the filesystem before the 24-hour limit and start a fresh sandbox from it\n5. Catch `ResourceExhaustedError` from `Sandbox.create()` on SDK 1.6.0 and later\n\n### Morph Cloud\n\n1. Set `ttl_seconds` and `ttl_action` when starting an instance. Nothing in the docs stops an instance with no TTL from billing MCUs\n2. Pass `auth_mode: api_key` when exposing an HTTP service. The default is `none`, which makes the URL public\n3. Enable `wake_on_ssh` before calling exec on an instance that may be paused. There is no separate exec wake setting\n4. Use `/api/instance/list` and `/api/snapshot/list` with `page` and `limit` (default 50, maximum 1,000). The plain list routes return everything\n5. On a 503 from snapshot, branch, pause or reboot, wait for the `Retry-After` value before repeating the call\n\n## Questions\n\n### Which is better for AI agents, Modal Sandboxes or Morph Cloud?\n\nModal Sandboxes scores 75.5 (BB) on agent readiness against Morph Cloud's 50.8 (D), and leads in every scored category.\n\n### Can an agent call Modal Sandboxes and Morph Cloud without installing anything?\n\nNo hosted endpoint is listed for Modal Sandboxes.
