## 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

## WatchTower

WatchTower is a DynamoDB capacity visualization tool created by the OS Labs team and published as an open-source project on GitHub. It addresses a common annoyance for developers: DynamoDB provisioning metrics are buried in AWS tooling, which makes it hard to tell whether a table is over-provisioned, under-provisioned, or changing shape over time. WatchTower centralizes that data and plots it in a purpose-built dashboard.

Setup is developer-oriented. You fork and clone the repository, add your AWS access key, secret key, and region to a local environment file, install dependencies, and start the app at localhost. From there you create an account (or sign in with GitHub), select a DynamoDB table, and choose a date range to generate metric graphs. An optional AI Integration panel calls Amazon Bedrock — the repository names Mistral 7B Instruct as the default — to produce written insights and recommendations about your provisioning levels. You can also save analyses for later and revisit them on a reports page to spot trends.

Privacy is a deliberate design point: because the app runs on your machine, AWS credentials stay in your local environment and are never transmitted elsewhere, with multi-user authentication layered on for shared computers. WatchTower is free and MIT-licensed, though the DynamoDB and Bedrock services it reads from are billed by AWS. The roadmap lists customizable alerts, analysis of auto-scaling and on-demand capacity, and customizable dashboards as in-progress additions.

**Pricing & Plans:** WatchTower is free and open source under the MIT license — you self-host it from GitHub. There are no subscription tiers, but Amazon Bedrock (used for AI insights) and DynamoDB itself are paid AWS services billed directly by Amazon Web Services.

- **AWS DynamoDB Integration:** Connect with an AWS access key and secret key, then browse and monitor the DynamoDB tables in your account.
- **Centralized Capacity Dashboard:** Pick a table and date range to generate clear graphs of provisioned versus consumed capacity, so you can judge whether provisioning is right-sized.
- **Amazon Bedrock AI Insights:** A one-click AI panel uses Amazon Bedrock (Mistral 7B Instruct by default) to turn raw capacity data into written insights and provisioning recommendations.
- **Saved Metrics & Historical Analysis:** Optionally save generated analyses and metrics to a DynamoDB table in your own account, then regenerate graphs later to compare trends over time.
- **Local, Multiuser and Private:** The app runs locally with signed-in multi-user support, light and dark themes, and AWS credentials that never leave your machine.

**Strengths:** Free and open source under the MIT license with the full source on GitHub; Purpose-built dashboard that makes DynamoDB provisioning metrics far easier to read than raw AWS consoles; Built-in Amazon Bedrock integration that turns metrics into plain-language recommendations; AWS credentials stay in a local environment file rather than on a vendor server

**Limitations:** Currently supports only AWS DynamoDB, with no other cloud or database backends yet; Because it runs locally, you must fork and clone the repo and manage your own Node environment and AWS credentials; Amazon Bedrock usage is billed separately by AWS and requires requesting model access in the Bedrock console; Several advertised features (custom alerts, auto-scaling and on-demand analysis, customizable dashboards) are still marked in progress
