## Which one, for what

### Morph Cloud (D)

Good for: Agents that need to checkpoint and fork a running machine with memory intact, for parallel attempts, evaluations or reinforcement learning rollouts.

Ahead on:
- Reliability, 63 against 55

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No terms of service, privacy policy, DPA or subprocessor list found on morph.so or cloud.morph.so

### Sprites (C)

Good for: Agents that need a long-lived machine with installed tools and files kept between sessions, and rollback by checkpoint.

Ahead on:
- Agent ergonomics, 68 against 61
- Security & auth, 59 against 39
- Payments & pricing, 30 against 20
- Maintenance & community, 80 against 58
- Transparency & trust, 59 against 25

Watch for: Four Sprites incidents on the status page in 90 days, including a partial outage of 7 hours 28 minutes on 23 September 2026 and failed creates outside Europe for 28 minutes on 8 October

## Verdicts

**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.

**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.

## Before you call either

### Morph Cloud

1. Set `ttl_seconds` and `ttl_action` when starting an instance. Nothing in the docs stops an instance with no TTL from billing MCUs
2. Pass `auth_mode: api_key` when exposing an HTTP service. The default is `none`, which makes the URL public
3. Enable `wake_on_ssh` before calling exec on an instance that may be paused. There is no separate exec wake setting
4. Use `/api/instance/list` and `/api/snapshot/list` with `page` and `limit` (default 50, maximum 1,000). The plain list routes return everything
5. On a 503 from snapshot, branch, pause or reboot, wait for the `Retry-After` value before repeating the call

### Sprites

1. Create a token at sprites.dev/account after a browser signup, and send it as `Authorization: Bearer <token>` to `https://api.sprites.dev`
2. 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
3. Set a network policy with `POST /v1/sprites/{name}/policy/network` before running untrusted code. Egress is open until one is set
4. Processes started by exec stop on a cold wake. Define a Service for anything that must answer the request that wakes the Sprite
5. Create a checkpoint before a restore. Restoring replaces the filesystem, ends active sessions and keeps no copy of the replaced state
6. 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
7. Delete Sprites you no longer need. An idle Sprite still bills cold storage for the bytes it holds
