Agent 37

Agent 37 is a hosting platform for AI agents. Through its Cloud API a single call provisions an always on sandbox running Hermes, OpenClaw, Claude Code, Codex or a custom harness, and each of your users can get their own sandbox whose files, memory, sessions and connected tools persist until you delete it. A browser based managed hosting service offers the same OpenClaw and Hermes agents to individuals without writing code. The Cloud API is aimed at developers building agent products for their own customers. Sandboxes support any model through the Agent 37 gateway or your own keys, connections to Gmail, Slack, Notion and more than 1,000 other apps, paid tools such as scrapes and lookups billed from the same balance, custom templates with preinstalled skills and plugins, file transfer, shell commands, embeddable terminal, desktop and file browser views, streaming events over Server Sent Events and scheduled runs. Hosting is white label by default, so you can resell agents under your own brand and set your own prices. The Cloud API has no subscription. Compute is metered per minute from a prepaid balance at $0.80 per vCPU, $0.70 per GB of RAM and $0.09 per GB of disk per month, which makes an always awake 2 vCPU, 4 GB instance $4.76 per month, 4 vCPU $9.34 and 8 vCPU $18.68. Sleeping sandboxes pay only for disk, performance instances cost four times the compute rate, and adding a card gives $5 of starter credit. Managed hosting plans are Free at $0 (one agent awake up to 10 hours a week), Basic at $3.99 per month, Plus at $9.99 with bundled model usage, Pro at $29.99 with a built in browser, and Max at $99.99 for teams with priority support and team roles. The company is backed by Y Combinator.
