Agent 37 Cloud

About Agent 37 Cloud

Agent 37 is a managed hosting service for persistent AI agents like Hermes, OpenClaw, and ClaudeCode. Instead of running these agents on self-managed servers or VPS instances, users spin up always-on, dedicated agents for each of their customers through a single API call. The platform also includes templates with pre-wired LLM access and integrations to over 1,000 tools via Composio.

Review

Agent 37 tackles the operational burden of hosting stateful agents for multiple clients. Founders and vertical-agent teams can avoid server babysitting and deliver a branded agent to each customer quickly. The service wraps agent deployment, isolation, and basic monitoring into a per-agent monthly fee.

Key Features

• Per-customer agent provisioning via API. One call creates a dedicated, always-on agent instance. A second call sends messages to it, using a pattern similar to the OpenAI Responses API.
• Pre-wired agent templates. Default configurations ship with LLMs and Composio tool integrations (Gmail, Calendar, Notion, and others), so agents can act on common SaaS tools immediately.
• Custom Docker image support. Teams that need their own API layer or tooling can replace the default template with a custom image, integrating proprietary systems.
• gVisor-based tenant isolation. Each customer agent runs in a sandboxed container, with security isolation comparable to the Modal platform. Container-level logs and resource monitoring track CPU, RAM, and abnormal behavior.
• Branding controls. Agents can carry the founder's branding, hiding the underlying Agent 37 infrastructure from end customers.

Pricing and Value

Pricing starts at $3.44 per month per persistent agent. The first agent instance is free and does not require a credit card. No volume-based tiers or additional pricing models are listed, so costs scale linearly with the number of customer agents deployed.

Pros

• Removes the need to run and maintain Mac minis or VPS for agent workloads.
• Dedicated agents are created with a single API call and stay on, so founders don't handle per-customer deployment scripts.
• Templates give agents immediate access to a large set of tools, reducing initial integration effort.
• Container-level isolation and monitoring help catch rogue loops or resource spikes without extra configuration.

Cons

• GDPR compliance and EU data residency are not yet in place. The team is working with early EU users and plans to add EU servers, but no concrete timeline is provided.
• Activity logs that an end customer could review (e.g., "what did the agent do this week?") are not built in. Founders must construct that reporting layer themselves on top of container-level logs.
• Teams needing fine-grained per-agent resource caps or automated kill-switches won't find those controls in the platform. Resource monitoring exists, but enforcement of limits depends on what the founder implements inside the agent sandbox.

Agent 37 fits founders who want to ship vertical agents like a CEO assistant or a clinic agent to their own clients without managing server fleets. It works best for teams already comfortable with Hermes, OpenClaw, or ClaudeCode and who need a straightforward per-agent pricing model. Organizations that prioritize turnkey end-customer audit trails or immediate EU compliance will need to plan for additional development alongside the service.
