Agent 37 Review (2026): Pricing, Features & Honest Verdict

Agent 37 Review: The Verdict

Agent 37 is managed hosting for AI agents like OpenClaw and Hermes. It hands you an isolated container with full terminal access and 850+ app integrations, so you skip the Docker and SSL setup. We found it cheap and fast to start. Best for: developers who want a hosted agent without DevOps. Price: from $3.99/mo (first instance free). Rating: 7/10.

What is Agent 37?

Running an open-source AI agent sounds simple until you actually do it. You need a server, Docker, SSL certificates, API keys wired up, and integrations configured. Then you have to keep it alive. Agent 37 removes all of that. It is a managed hosting service that gives you a pre-configured container running OpenClaw, Hermes, or your own image, with full terminal access from a web browser.

It was built by a small team, Amanda Silmon, Vishnu, and fmerian, and it launched with an aggressive price: $3.99 a month for a real agent instance. There is also Agent 37 Cloud, a separate product where one API call spins up a persistent agent for each of your customers, running under your brand. That second piece is aimed at SaaS builders who want to ship agents to their users without standing up infrastructure per customer.

What are Agent 37’s key features?

Managed containers with full terminal access

Each instance is an isolated container with 1 vCPU and 4GB of RAM on the base plan. You get a web terminal, a file browser, and live desktop access. This matters because agents do real work on a real machine. You can SSH in, inspect what the agent did, and fix things by hand. It is not a black box.

850+ app integrations out of the box

Agent 37 wires up connections to Gmail, Slack, Notion, and hundreds more so your agent can act across your stack on day one. Setting these up manually is the tedious part of self-hosting, and having them ready is a genuine time saver.

Bring your own keys, or use included tokens

You can plug in your existing ChatGPT or Claude subscription, or use roughly $1 of free tokens that come with the subscription each month. The bring-your-own-key model is the honest one. You are paying Agent 37 for the hosting, not a marked-up token reseller fee.

Agent 37 Cloud for per-customer agents

This is the developer play. One API call creates a working agent on a persistent computer, branded as yours, starting from $3.44/mo per customer billed hourly. If you sell software and want every user to have their own agent, this saves you from building a fleet of sandboxes yourself.

How much does Agent 37 cost?

The base plan is $3.99/mo and includes 1 vCPU, 4GB RAM, full terminal access, and about $1 in tokens. Higher tiers add more resources and API limits. Agent 37 Cloud starts at $3.44/mo per customer instance, billed hourly, and the first instance is free with no card required. That free-first-instance offer makes it trivial to test.

For context, self-hosting OpenClaw yourself runs roughly $5 to $10/mo for a VPS plus your API usage, and competing managed services like OpenClaw Launch charge $6 to $20/mo. Agent 37 lands at the bottom of that range, and the per-customer hourly billing on Cloud is the kind of pricing that actually fits a SaaS cost model.

Who is Agent 37 best for?

Use Agent 37 if you want to run an OpenClaw or Hermes agent and you do not want to babysit a server. The price is low enough that it beats the hassle of a VPS for most people. Also use Agent 37 Cloud if you are a founder shipping agents to customers and need isolated instances per user without building the plumbing.

Skip Agent 37 if you already run your own infrastructure comfortably and want full control over the host. And skip it if your agent needs serious compute, because 1 vCPU and 4GB on the base tier is fine for routine tasks but not for heavy workloads. Check the higher tiers first.

What are the best Agent 37 alternatives?

Self-hosting on a VPS. Run OpenClaw or Hermes on a $5 DigitalOcean or Hetzner box. Maximum control, more work. Pick it if you enjoy managing servers.

OpenClaw Launch. Another managed OpenClaw host, $6/mo on Lite or $20/mo on Pro, with AI credits included. Slightly pricier but bundles tokens.

E2B or generic sandboxes. Cloud sandboxes for running agent code. More of a building block than a finished product, better if you want to assemble your own stack.

Final verdict: Is Agent 37 worth it?

Agent 37 nails a real pain point. Self-hosting agents is annoying, and paying $3.99 a month to make the annoyance disappear is an easy call. The full terminal access keeps it from being a locked-down toy, and the 850+ integrations save hours of fiddling. For a hobbyist or a developer who just wants their agent running and reachable, this is a clean answer.

Agent 37 Cloud is the more interesting bet. Per-customer, hourly-billed, branded agents via one API call is exactly what a SaaS company needs, and the free first instance lowers the barrier to trying it. The team is small and the product is young, so expect some rough edges and keep an eye on whether base-tier resources fit your agent. With those caveats, we rate it 7 out of 10. Strong value, clear use case, early days.
