## Which one, for what

### E2B (B)

Good for: Code interpreters and agent workspaces that pause and resume with memory, and teams that may want to self-host later.

Ahead on:
- Schema & documentation, 92 against 72
- Security & auth, 62 against 39
- Payments & pricing, 50 against 20
- Maintenance & community, 88 against 58
- Transparency & trust, 68 against 25

Also in its favour:
- Free to start without a card
- Open source

Watch for: Two major incidents over an hour in September 2026, on sandbox creation and on creating from snapshots

### 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.

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

## Verdicts

**E2B.** Firecracker microVM with its own kernel per sandbox. Two major incidents over an hour in September 2026, on sandbox creation and on creating from snapshots.

**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.

## Before you call either

### E2B

1. Set a timeout when you create a sandbox. The default is 5 minutes
2. Pause rather than kill when you'll come back. Resume takes about a second and nothing is billed while paused
3. Use `Secret.fill` in network transforms instead of passing API keys into the sandbox environment
4. Pace sandbox creation. Hobby allows 1 a second and 20 running at once
5. Move to the v2 sandbox endpoints. SDK 2.51.0 and later use them by default

### 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
