## Summary

Rohan Paul highlights Agent37, a sandbox for AI agents priced at $4.76 for a month of running 2 vCPUs and 4 GB RAM. The quoted launch post compares that with Vercel at $249, Cloudflare at $145 and Daytona at $121, and says each harness runs in a gVisor sandbox with its own filesystem and hard disk quota.

## Why it matters

The source compares monthly sandbox prices across providers and names the isolation setup, helping developers weigh cost against what each agent environment actually provides.

## Post

This is a really useful launch. 

When you ask an AI agent to build an app or analyze files, it needs a computer to actually run that work, and that computer has been surprisingly expensive. 

Agent37 now offers one for $4.76 for a month-long sandbox, which makes it cheap enough for apps to give every user their own permanent agent.

It runs each harness (Claude Code, Codex, OpenCode, Hermes or your own Docker image) in a gVisor sandbox with its own filesystem and a hard disk quota

> Sandboxes have no moat. Just fat margins. We're launching http://agent37.com to kill those margins.

> Vercel: $249
> Cloudflare: $145
> Daytona: $121
> Agent37: $4.76

> If you can find a cheaper sandbox and we'll refund the difference.
