Hosted Linux computers for agents, sold two ways: a prepaid Cloud API and a one-click personal-agent subscription.
Short answer: One always-on personal agent (2 vCPU / 4 GiB / 20 GiB) costs about $10.60 a month here, the cheapest of the 11 providers that run it as described. The AI model adds about $14.70 a month on top (GLM 5.3, 30 requests a day at 40k tokens each, median zero-retention price; from $6.84 at the cheapest host). Fits well: An always-on agent that must not sleep: auto-sleep is off by default and there is no lifetime cap.
Agent 37 is an early-stage company (Y Combinator, Fall 2026) running two products under one brand. Agent37 Cloud is a prepaid API for persistent sandboxes: a gVisor container by default, or a full VM as an option, whose whole disk survives between runs and which can sleep when idle.
Managed hosting is the consumer side: a flat monthly plan for a pre-installed OpenClaw, Hermes, Claude Code, Codex, OpenCode or Grok agent, with a browser dashboard, task board and chat channels. It has no public API of its own.
The split matters for this site. A non-technical buyer usually wants the second product, while almost every feature described here belongs to the first.
| Who it is for | Developers building one sandbox per end user, and non-technical buyers who want a personal agent without touching an API. |
|---|---|
| Isolation | gVisor container by default: a user-space kernel, stronger than a plain container but weaker than a VM, and Docker does not work inside it. The vm type gives a full VM with its own kernel at 2.5× compute; performance gives dedicated cores at 4×. |
| Sizes | Four shapes, with 4 vCPU as the ceiling on the default type: 2/4, 4/8, 4/16 and 4/32 vCPU/GB. Disk is any whole number of GB inside each shape's range, defaulting to 4, 6, 12 or 24 GB. |
| A personal agent here | About $10.60 a month for one always-on 2 vCPU / 4 GiB machine (4/8: 4 vCPU / 8 GiB / 20 GiB), before the AI model. Change the numbers |

Our reading of the sourced material on this page, not a provider claim.
| Model | Prepaid wallet, no subscription and no plan fee. |
|---|---|
| Meter | Per minute, priced from the shape you reserved: $0.80 per vCPU-month, $0.70 per GB-month, $0.09 per GB-month of disk. |
| While stopped | Disk only. A sleep checkpoint keeps memory at no extra charge; a stopped instance loses memory and still pays for disk. |
| Plan fee | None on the Cloud API. The personal plans ($3.99 to $99.99 a month) are a separate product. |
| Minimum | No minimum charge, but creating an instance requires one day of its running cost in the wallet. |
How Agent 37 lets you try before paying is on Trials and free tiers.
| Dashboard | Yes, two of them: agent37.com/dashboard/cloud for keys, billing, team and metrics, and a separate dashboard for the personal-agent product. The docs never describe creating a Cloud sandbox by clicking, so the documented path is an API call or the CLI. |
|---|---|
| Without code | On managed hosting, yes, that is the whole product: one click, a task board, a web terminal, a file browser and a live desktop. On the Cloud API, no: every create path in the docs is POST /v1/instances, npx agent37, or a code snippet. |
| Signup | Cloud needs a card to unlock the $5 starter credit, or you can sign up through the API with no credit and fund it first. The personal free plan needs no card. |
| Docs and support | Mintlify docs, over 60 pages, runnable examples for every endpoint, and llms.txt bundles so an agent can read the whole manual. Support is a founder's email, a dashboard chat bubble and a booking link. There is a public status page. |

Shown as the research found them. A contradiction means the provider's own pages disagree; an open question means the answer is not published.
The sizing page says 4 vCPU is the ceiling on every instance type and that a request for 16 vCPU comes back as 4. The VM page prices 8 vCPU / 16 GB and 16 vCPU / 32 GB. Both pages are current.
Its snapshot: mem and $0.03 figure describe the sleep checkpoint and cold storage, not a snapshot product you can name, list or clone. There is no snapshot product.
No per-GB rate, free allowance or overage policy appears on the pricing page or in the billing docs.
Every documented create path is an API call or CLI command. The absence may be a documentation gap rather than a product gap.
EU and India regions keep the instance and its disk local, but backups and the control-plane record are stored in the US.
battleships.dev recorded a conflict between a $5 website claim and $1 in the billing docs. The billing docs said $5 on 2026-10-28, so it appears resolved, but the number has changed at least once.
