Verdicts

Blaxel Sandboxes

No compute charge in standby, only $0.20 a GB-month of snapshot storage. 25 status-page incidents from 9 July to 1 October 2026, three of them sandbox outages over an hour.

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

Blaxel Sandboxes

  1. Close WebSocket and terminal connections when done. An open connection keeps the sandbox active and billed
  2. Set a TTL or idle expiry on throwaway sandboxes. The default is to keep them
  3. Set forbiddenDomains or an allow list at creation, with network.firewall for tools that ignore proxy settings. Both can only be set when the sandbox is created
  4. Retry only on WORKLOAD_UNAVAILABLE. The error reference says other codes won't succeed on retry
  5. Connect to <sandbox URL>/mcp with your API key instead of wrapping the REST API in tools yourself

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

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
