[01] Architecture

Every customer gets their own agent instance

One call provisions an instance per customer. Message it across as many sessions as you like. Its files, memory, and connected tools stay put until you delete it.

[02] Pricing

Pay for compute, not seats

One instance is one customer, metered per minute from a prepaid balance. The number below is your cost per customer, always on. Less than a basic VPS, with the agent, API, and routing included.

Delete anytime

Billing is metered per minute and stops the moment you delete.

Your model keys or ours

Bring your own keys, or meter models from the same balance with per-instance spend caps.

Expandable disk

Add disk to any instance for $0.09 per GB per month.

[03] Why

Don't stitch together VPSs for every agent

To give every customer a persistent agent, you end up renting boxes, running containers, tracking state, streaming responses, and controlling costs. On Agent 37, that is one POST.

No VPS to babysit

No stateful servers to provision, patch, or keep alive. Instances are always-on and managed for you.

No adapter to build

We wrap each agent's CLI or SDK in a clean REST API with streaming, so you never write or host the glue.

No proxy to wire

Every port of every instance is already routable at https://{id}.agent37.app, behind your key or a signed URL. No reverse proxy, no DNS, no certificates.

[04] White-label

White-label OpenClaw and Hermes under your own brand

Resell hosted OpenClaw and Hermes agents as your own product. You buy compute at cost, set your own pricing, and keep the margin. You hold the API key, so customers see only your brand.

Resell with strong margins

Start from low-cost managed hosting metered per minute from a prepaid balance, then price your own support, onboarding, and vertical workflows on top.

Ship branded deployments

Launch an OpenClaw or Hermes instance per customer under your own offer while we run the isolated runtime underneath.

One API, preloaded templates

Provision each customer with a single POST, package templates with your own skills and prompts, and cap per-instance spend so no account runs away with your costs.

[05] Templates

Pick your template

Pick a template from our catalog, or build your own custom Docker image and configure the ports to expose. Each routes authenticated traffic to your sandbox.

Hermes

The default. Chat, browsing, code, and files. Message it the moment it exists.

OpenClaw

Your channels-and-models agent, hosted behind the same API.

Claude CodeComing soon

Anthropic's coding agent on a computer of its own.

Custom

Any public Docker image, registered under a name. Build on the Hermes base or start from scratch.

[06] Capabilities

Everything an agent product needs

Every one acts on the instance you already created. Nothing extra to deploy.

Any model

Use any model through our gateway, or bring your own keys.

Integrations

Connect Gmail, Slack, Notion, and 1000+ apps. Routed and metered for you.

Custom skills & plugins

Preinstall your own skills, prompts, and tools with a custom template.

Files

Upload files to an instance and download what the agent creates, straight from your backend.

Run commands

Run any shell command inside the instance from your backend.

Streaming events

Text, reasoning, and tool activity live over Server-Sent Events.

Scheduled runs

Give an agent a cron schedule; it runs unattended and you read the results.

Terminal, desktop & files

Embed a live terminal, desktop, or file browser with signed URLs.

[07] Built for production

Ship agents under your own brand

Your brand on top, kernel isolation underneath, and a spend cap on every instance.

White-label by default

You hold the key. Your customers see only your product, never Agent 37.

One instance per customer

Each customer gets a persistent computer: files, memory, and connected accounts that stay put.

Kernel-level isolation

Every instance runs under the gVisor runtime with a hard per-instance disk quota.

Prepaid, usage-based

Top up a balance and set a per-instance spend cap. No seats to negotiate.
