## 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

## Composio

Composio sits between your AI application and the outside world. Instead of hand-coding an integration for every SaaS product your agent needs, you pick from a large catalog of pre-built toolkits, and Composio handles the tedious parts: OAuth authorization, credential storage and refresh, per-action permission scopes, and execution. The same catalog powers both agent frameworks (via SDKs and function calling) and MCP-compatible clients such as Claude, ChatGPT, Codex, and Cursor, which can connect through a single managed MCP endpoint.

The platform has expanded well beyond simple tool calling. Triggers let agents start background work in response to events in connected apps. Firewall inspects tool results and blocks hidden prompt-injection instructions before the model reads them. Instant tools provide audio, video, search, browser, and data capabilities without managing your own API keys, and optimization features aim to lower the cost per completed task. Enterprise controls add SSO, governance, and audit trail support.

The product is aimed primarily at engineering teams building agents or agentic backends, and secondarily at knowledge workers who want Claude or ChatGPT to operate their everyday apps. It follows a freemium model with a free developer tier and paid tiers plus custom enterprise agreements, and the company states SOC 2 Type II compliance.

**Pricing & Plans:** Freemium. A free developer tier is available for getting started, with paid plans and custom enterprise pricing for higher usage, team controls, and security requirements. Exact tier limits are published on Composio's pricing page; contact sales for enterprise terms.

- **1,700+ app toolkits:** A large catalog of pre-built integrations spanning productivity, CRM, support, engineering, finance, HR, and e-commerce apps, each exposing callable actions to your agent.
- **Managed authentication:** Composio runs OAuth flows, stores and refreshes credentials, and enforces per-action permission scopes so agents act only where you allow them.
- **MCP gateway:** One managed MCP endpoint that connects Claude, ChatGPT, Codex, Cursor, and other MCP clients to your entire tool catalog in a few clicks.
- **Triggers:** Start background agents from events occurring across connected apps, so work can begin without a user prompt.
- **Firewall and enterprise governance:** Inspect tool outputs to block injected instructions, and add SSO, audit trails, and org-wide policy controls for regulated deployments.

**Strengths:** Very large integration catalog, which removes most custom API glue work; Handles the hard parts of auth: OAuth, token refresh, and scoping; Works with both code-first SDK flows and no-code MCP clients; Safety features such as Firewall and enterprise governance are uncommon in this category

**Limitations:** Deeper capability comes with a learning curve around toolkits, actions, and auth configs; Free tier limits are modest, so production use generally requires a paid plan; Behaviors and available toolkits change frequently, so docs must be checked often
