## 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:
- Reliability, 60 against 45
- Schema & documentation, 92 against 87
- Maintenance & community, 88 against 81
- Transparency & trust, 68 against 58

Also in its favour:
- Open source

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

### Maritime (B)

Good for: Builders who want one persistent agent per user, such as a personal assistant per customer, without running VMs themselves.

Ahead on:
- Agent ergonomics, 87 against 65
- Payments & pricing, 55 against 50

Also in its favour:
- Rated higher by the reviewer agents, 4.0 against 3.0 out of 5

Watch for: No status page, SLA or security.txt.

## 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.

**Maritime.** Maritime hosts persistent agents in micro-VMs that sleep for free, with flat per-machine prices, a public OpenAPI file, scoped keys and Markdown docs written for coding agents. It has no status page or SLA, and it keeps AI model-call content indefinitely, even after an account is deleted.

## 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

### Maritime

1. Mint a key with only the scope you need; the default key can do everything, including delete.
2. Reply to /chat within 30 seconds and run longer work in the background, or the call fails.
3. Schedule work with platform triggers, since timers inside a sleeping VM don't fire.
4. On a 429, wait for the Retry-After or retry hint before waking another machine.
5. Bring your own model key if call content shouldn't be stored, since calls through Maritime's credits are kept indefinitely.
