Agent 37

The low-cost cloud sandbox where AI agents actually live

Per-minute sandbox billing

Pay for vCPU, memory and disk separately while the sandbox runs; when it sleeps or is deleted the compute meter stops and you are left with disk cost only.

Ready-made agent harnesses

Launch Claude Code, Codex, OpenClaw, OpenCode, Hermes, Grok or your own Docker image, each in its own tenant-isolated sandbox.

Persistent workspace and scheduling

Files survive sleep, restarts and weeks of inactivity, and agents can be attached to cron-style schedules so work runs unattended.

Networking and custom domains

Expose individual ports publicly, attach your own domain, or keep everything behind an API key on an authenticated URL.

Strengths & Pros

+Aggressively low per-minute pricing with an explicit public comparison against major sandbox providers
+Persistent disk and scheduling make it suitable for real agent workloads rather than one-shot tasks
+Strong isolation story (gVisor, firewalled egress, no public hostnames) plus SOC 2 Type I
+Flexible model and tool sourcing: platform gateway, bring-your-own keys, or pay-per-use tools
