## 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

## ChartDB

ChartDB attacks a familiar annoyance: understanding an unfamiliar or sprawling database schema. Rather than installing a heavy modeling suite with database access, it asks you to run one read-only query per DBMS — the project publishes a ready-made query for PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, ClickHouse, CockroachDB, Oracle, Snowflake, and BigQuery. Paste the output JSON and you get a full, interactive ER diagram that you can rearrange, annotate, and export.

Beyond visualization, ChartDB works as an editor. You can add tables, subject areas, and sticky notes, edit relationships, use a DBML editor for text-driven modeling, and produce clean DDL scripts in your preferred SQL dialect. The AI ER diagram generator goes the other direction: describe what you want and get an editable, optimized schema draft. Diagrams are also exportable as images or embeddable previews for docs and wikis.

The project is open source under AGPL and has accumulated tens of thousands of GitHub stars, which is why a self-hosted deployment is available alongside the Cloud product. Cloud plans add real-time collaborative editing, database auto-sync that keeps diagrams current as the schema changes, change logs and versioning, and an AI assistant. Teams get multi-user workspaces, 2FA, and priority support; larger organizations can request custom SSO and RBAC terms.

**Pricing & Plans:** ChartDB offers a genuinely free open-source tier (self-hosted, AGPL) that includes all core features and up to two diagrams. Cloud plans run about US$25/month for a single user (Pro) and US$59/month for teams, with annual billing discounts of up to 40%. Custom enterprise pricing covers SAML SSO and granular permissions.

- **One-query schema import:** Paste a single read-only query result and ChartDB renders the whole schema as an ER diagram, with no direct database access or local agent required.
- **AI ER diagram generator:** Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL.
- **DDL and diagram export:** Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation.
- **Auto-sync and versioning:** On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift.
- **Real-time collaboration:** Invite teammates to view and edit diagrams simultaneously, with multi-user workspaces and 2FA on team plans.

**Strengths:** Truly open source with a generous free self-hosted option and no database access needed; Fast setup — a single query gets you a complete interactive diagram in seconds; Broad DBMS coverage including PostgreSQL, MySQL, SQL Server, SQLite, ClickHouse, Snowflake, BigQuery, and Oracle; AI generation works both ways: prompt-to-diagram and diagram-to-DDL

**Limitations:** Cloud collaboration, auto-sync, and the AI assistant are paid; the free self-hosted tier limits you to two diagrams and ten tables each; Snowflake and BigQuery support sits on higher-tier plans; As a specialized ERD tool it does not replace a full data-governance or lineage platform
