Agent 37

What is Agent 37?

Agent 37 provides cloud sandboxes for hosting AI agents, running ready-made harnesses like Hermes or custom Docker images. It targets startups and developers building agent products by isolating each customer's tools, files, and credentials in a separate environment. Billing is prepaid and metered per minute of compute uptime, with no subscription required.

What are the features of Agent 37?

• Sandbox isolation

  Each sandbox runs on gVisor with its own filesystem and hard disk quota, preventing tenants from seeing each other's workloads.
• Auto-sleep lifecycle

  Sandboxes pause when idle to stop compute charges and wake automatically upon new requests.
• Persistent storage

  Files written to disk survive restarts, sleep cycles, and sessions, with automatic backups available for restoration.
• Authenticated networking

  Exposes public ports or custom domains through Cloudflare's edge over TLS, requiring an API key unless a port is explicitly made public.
• Scheduled execution

  Assigns cron schedules to agents so they run unattended while users read the results later.
• Observability dashboard

  Tracks CPU, memory, and disk usage alongside logs to monitor what ran inside each sandbox.

What are the use cases of Agent 37?

• Live coding platforms

  Vision assigns a dedicated, sized machine to every live coding session to prevent CPU problems across multiple instances.
• Nonprofit fundraising tools

  Boon provisions individual Hermes agents for nonprofits to assist with grant fundraising workflows.
• Always-on customer agents

  Perflo ships a continuously running agent per customer without managing backend infrastructure or hiring DevOps staff.
