## 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

## Archal

Archal targets the messy reality of integration testing for AI agents. Agent workflows call many third-party APIs in sequence, and real test accounts bring rate limits, shared mutable state, and flaky results. Archal replaces those accounts with sandboxes: time-bounded runtimes containing one or more stateful environments. Each environment mimics the paths, methods, payloads, and response shapes developers already know, retains mutations for the life of the sandbox, and can be reset to a declared baseline so every test run starts from the same known state.

A sandbox can hold multiple environments at once, and a single Archal API key manages all of them through one gateway. That makes it practical to give each CI job or feature branch its own sandbox, to keep test runs isolated from one another, and to run reinforcement-learning or agent-training rollouts where each episode must begin from an identical starting point while changes persist through the episode. Archal also ships a guided skill that connects Claude Code, Codex, Cursor, or Devin to the environment catalog via a single npx command, so coding agents can provision their own sandboxes.

Environments are Archal-managed simulations, not the providers' live services, and the company documents each environment's capability profile and exceptions rather than claiming blanket upstream parity. Pricing is usage-based: $0.10 per environment-minute, billed by the second, with failed provisioning and cold-start time free, and $20 in starter credits ($5 after verified signup plus $15 when the first sandbox is ready).

**Pricing & Plans:** Usage-based with a free starting allowance: $5 in credits after verified signup and $15 more when your first sandbox becomes ready, then $0.10 per environment per minute, prorated by the second. No card required to start; failed provisioning and cold-start time are not billed. Paid continuation tiers are being rolled out gradually.

- **Stateful simulated environments:** Spin up environments for GitHub, Slack, Stripe, Linear, Supabase, Datadog, HubSpot, Jira and more that persist mutations during a run and reset to a declared baseline on demand.
- **REST and MCP interfaces:** Call environments through familiar REST paths and payloads or through MCP tools, so existing agent code and tool definitions work with minimal changes.
- **One key, many sandboxes:** A single API key creates and manages every sandbox and environment, with shared gateway routing while each environment keeps its own endpoint and readiness state.
- **Multi-environment sandboxes:** Combine every environment a workflow needs into one sandbox, giving each its own readiness state and endpoint so end-to-end agent flows can be tested together.
- **CI, branch and RL isolation:** Give each CI job, branch, or RL rollout its own sandbox with an identical starting state — ideal for harness testing, integration testing, and agent training.
- **Setup skill for coding agents:** Install with one npx command and let Claude Code, Codex, Cursor, or Devin verify access to the full environment catalog before you write any application code.

**Strengths:** Eliminates test-account headaches such as rate limits, shared state, and flaky third-party dependencies.; Familiar REST and MCP surfaces mean existing agent code often works with little or no change.; Second-level billing with free credits and no card required keeps experimentation cheap.; Sandbox reset gives reproducible test runs, which is hard to achieve against live APIs.

**Limitations:** Environments are Archal-built simulations, so behavior may not match every edge case of the real provider.; Paid continuation options are still rolling out, which limits options for long-running production use.
