Quickstart

Get a service live on Ratel in under a minute.

1. Create your account — register a free Sandbox workspace; no credit card required.
2. Connect a repository — push your code; Ratel's Nixpacks engine autodetects Python and Node.js with zero config.
3. Deploy — every service instantly receives a secure URL at https://[service]-[hash].up.getratel.com with automatic HTTPS.
4. Scale — upgrade to a paid plan from your dashboard whenever you ship.

MCP servers

Ratel hosts remote Model Context Protocol servers over HTTPS and speaks both MCP wire transports, so Cursor, Claude Code, Claude Desktop and the MCP Inspector all connect with no glue code:

• Streamable HTTP (recommended) — POST /mcp/{server}. One JSON-RPC request per call; the reply is application/json or an SSE stream, and an Mcp-Session-Id header keeps your session sticky.
• HTTP + SSE (legacy) — GET /mcp/{server}/sse opens the event stream (the first event tells your client where to POST messages).

HTTP-native MCP servers (FastMCP, the TypeScript SDK, …) run as ordinary containers and are reached over the transports above. Authenticate with a Bearer token from your workspace. Every workload runs under hardened cgroups with TLS everywhere and per-tenant isolation.

Connect your AI agent

Point any client at https://api.getratel.com/mcp/<your-server> and pass your token. Replace my-server and rtl_YOUR_TOKEN below.

Cursor — ~/.cursor/mcp.json

{
  "mcpServers": {
    "my-server": {
      "url": "https://api.getratel.com/mcp/my-server",
      "headers": { "Authorization": "Bearer rtl_YOUR_TOKEN" }
    }
  }
}

Claude Code — one command

claude mcp add --transport http my-server \
  https://api.getratel.com/mcp/my-server \
  --header "Authorization: Bearer rtl_YOUR_TOKEN"

Claude Desktop — claude_desktop_config.json

{
  "mcpServers": {
    "my-server": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote",
        "https://api.getratel.com/mcp/my-server",
        "--header", "Authorization: Bearer rtl_YOUR_TOKEN"
      ]
    }
  }
}

Backends

Deploy Python and Node.js backends with Git push-to-deploy. Every open pull request spins up a per-PR preview deployment, and containers run unprivileged with all Linux capabilities dropped, hard memory caps, and CPU quotas.

Databases

Provision managed PostgreSQL, MySQL, and MariaDB directly from your dashboard. Each database runs in its own hardened container bound to a host-mounted persistent volume scoped to your workspace, reachable only on your private tenant network — never exposed to the public internet — with freshly generated credentials. PostgreSQL databases are backed up daily as logical dumps to per-tenant object storage; the last backup time is shown on your dashboard and restores are operator-assisted.

Business email

Send from your own domain through a DKIM-signed smart-host relay that protects your sender reputation, with inbound mail routed to your inbox. Ratel configures your DNS holistically (MX / SPF / DKIM / DMARC) under one table and mints per-workspace DKIM keys.

API reference

Authenticate API requests with a Bearer token from your workspace.

• POST /proxy/{path} — authenticated reverse-proxy to your tenant compute. Streams text/event-stream for SSE. Consumption is metered automatically.
• GET /healthz — service health probe.
• POST /webhooks/github — Git-to-deploy webhook (signature-verified).
• POST /webhooks/stripe — billing events (signature-verified).

Billing & plans

Start on the free Sandbox tier and upgrade to Professional ($12/mo) or Enterprise ($45/mo) at any time. Manage your subscription — upgrade, downgrade, or cancel — from the dashboard via the secure Stripe Customer Portal. See Refund Policy and full pricing.
