What it offers
Agent37 hosts separate sandboxes for customers’ AI agents, with persistent files, sleep and wake behavior, browser and terminal access, and metered compute and disk. Its English product site lists harnesses including Hermes, OpenClaw, Claude Code and Codex. The founder announced a free plan in an October 12 Launch HN post; the public site advertises a starting credit and usage-based pricing.
Claims and limits
The founder attributes low operating costs to burst-aware resource allocation, lower-cost server vendors and gVisor isolation. Those cost and security comparisons are company claims. The post says its gVisor sandboxes do not support Docker-in-Docker or Android emulators, while fuller virtual-machine sandboxes are available at a higher price.
