Coding / Agent37

Agent37

Cheap persistent sandboxes for Hermes, OpenClaw, Claude Code and similar agents. Compute sleeps with the box; model tokens are separate. Best if you already run agents and just need a host that does not dominate the bill.

My score

73 out of 100

Price

$5 starter credit after card; then ~$0.80/vCPU + $0.70/GB RAM + $0.09/GB disk per 730-hour month, metered by the minute (typical small sandbox ~$0.37–$4.76/mo depending on hours)

From Asia-Pacific

Cloud API from anywhere; YC F26; compares well on list price versus E2B, Modal and Railway sandboxes.

If Agent37 isn't right

• Cursor in coding

  The editor most builders end up in: codebase-aware edits that actually land.

  Free tier; Pro from $20/mo

• Claude in coding

  My pick for anything long: contracts, big codebases, a messy brief. It reads carefully and says when it isn't sure.

  Free tier; Pro from $20/mo

• GitHub Copilot in coding

  Safe default for teams already on GitHub; strong autocomplete, solid chat.

  Free tier; Pro $10/mo

• Replit in coding

  Idea to a running URL without installing anything. The code gets messy if you keep going, so treat it as a sketchpad.

  Free tier; paid plans available
