## Agent 37

Agent 37 is a cloud infrastructure product aimed at people who need somewhere real for AI agents to run. Instead of a chat window, every customer gets a sandbox: an isolated Linux container with CPU, memory, persistent disk, an optional public HTTPS URL, and outbound network access. The company positions itself primarily on price, claiming its sandboxes cost roughly 94% less than most competing providers and publishing a comparison table against AWS, Daytona, E2B, Modal, Vercel, and others. Billing is prepaid and metered by the minute — vCPU, memory, and disk each have their own unit rate — with no subscription fee.

Beyond raw compute, Agent 37 ships a layer of agent-specific conveniences. You can start from a ready-made harness such as Claude Code, Codex, OpenClaw, OpenCode, or Hermes, or bring your own Docker image. Agents keep their files across sleep, stop and restart cycles, and can be given cron schedules so they run unattended and simply report results. Model access can come from the platform gateway (Claude, OpenAI, Gemini, Grok) or from your own API keys, and integrations cover services such as Gmail, Slack, Notion, and GitHub through a Composio-based connector catalog, plus metered access to paid tools like web scraping and people/company data.

Security is a major part of the pitch: sandboxes are isolated with gVisor, hosts have no public hostname, ingress goes through Cloudflare with API-key authentication, and outbound traffic is restricted to the public internet. The company states it does not collect prompts, files, or terminal sessions, holds SOC 2 Type I, and is working toward Type II. It also offers startup credits and a free personal agent tier for individuals who just want an agent of their own.

**Pricing & Plans:** Prepaid, pay-as-you-go compute metered per minute with no subscription or minimum. New accounts get a $5 starter credit once a card is on file, and the company advertises up to $10,000 in credits for startups. Exact unit rates are published on the pricing page and change over time, so confirm current figures there.

- **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.
- **Integrations and metered tools:** Connect 1,000+ apps such as Gmail, Slack, Notion and GitHub, and buy one-off capabilities like scraping or enrichment from the same balance.

**Strengths:** 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

**Limitations:** Prepaid balance model means you must top up in advance and monitor spend across many sandboxes; Persona pricing and plan details are only available after contacting the team for the white-label and enterprise tracks; Documentation and benchmark claims are largely self-published, so independent verification is limited

## Defang

Defang targets the gap between fast local prototyping and real production hosting. You describe your app with a familiar Docker Compose file, and Defang provisions the underlying cloud infrastructure in your own AWS, GCP, or Azure account. That keeps the cloud account, data, and model choices in your control instead of locking them into a vendor's hosting. The platform provides preview environments so changes — including agent-generated ones — can be reviewed before they reach production, and it offers a single deployment path shared by both people and AI agents.

The current product line has three parts. Defang Station is a hosted runtime where coding agents such as Claude Code or Codex run against your own Anthropic and OpenAI accounts, accessible from a browser. Defang Deploy is the Compose-to-cloud path described above. Defang Forge is a services engagement in which engineers work inside your codebase and cloud accounts to redesign how your team ships software, then hand the workflow back to you.

Defang frames its value around "engineering sovereignty": your advantage stays portable, observable, and yours. The site also publishes an AI-Native Maturity Model and a related assessment to help organizations see where their delivery workflow bottlenecks. It is a developer-focused tool, so expect a command-line and Git-oriented workflow rather than a no-code interface.

**Pricing & Plans:** Freemium-style offering with a free tier to start; paid plans and a contact-for-pricing option are available. Check the pricing page for current tiers.

- **Compose to your cloud:** Deploy a Docker Compose file into your own AWS, GCP, or Azure account without managing Kubernetes by hand.
- **Preview environments:** Spin up review environments for changes, including those produced by AI agents, before promoting to production.
- **Defang Station agent runtime:** Run coding agents such as Claude Code or Codex against your own Anthropic and OpenAI accounts, reachable from any browser.
- **Defang Forge engineering program:** Work with Defang engineers inside your codebase and cloud accounts to rebuild your delivery workflow.
- **AI-Native maturity guidance:** Use the published maturity model and assessment to find the bottlenecks limiting your AI return on investment.

**Strengths:** Deploys to your own cloud account, keeping data and infrastructure under your control; Uses Docker Compose, so existing container projects need little rework; Preview environments make it safer to ship agent-generated changes; Combines tooling with services (Forge) for teams that want workflow redesign, not just features

**Limitations:** Aimed at developers; there is no drag-and-drop or no-code path; You still need some cloud and container familiarity to get the most from it; Pricing for higher tiers requires checking the pricing page or contacting sales
