Agent 37
Host any agent harness in an isolated sandbox.
About
Agent 37 provides fully managed, isolated sandboxes for running AI agent harnesses such as OpenClaw, Claude Code, Hermes, and custom Docker images. It offers persistent storage, terminal access, and integrations with over 1,000 apps via Composio. The platform handles infrastructure concerns like isolation (enforced by gVisor), networking, and billing, allowing developers to deploy agents that run 24/7 or on schedules. Pricing is usage-based, charging per minute of uptime and per GB of disk, with costs significantly lower than traditional cloud providers or specialized sandbox competitors.
Key Features
- Isolated sandboxes using gVisor
- Support for multiple agent harnesses (Hermes, OpenClaw, Claude Code, etc.)
- Persistent disk storage
- Full terminal access
- Scheduled runs (cron jobs for agents)
What Makes It Different
Specialized infrastructure for AI agents with persistent state and background execution, priced on a pay-per-minute model that undercuts major cloud and sandbox providers.
Pricing
Pay-as-you-go. $5 free credit for new accounts. Compute billed per minute (e.g., $0.37 for 1 vCPU/4GB), disk billed per GB retained ($0.
