What It Does

mycrab.space is a zero-configuration self-hosting platform that enables AI agents to deploy and expose applications from any device with a public URL—no port forwarding, no VPS, and no traditional deployment required. By providing AI agents with a single skill file, mycrab transforms complex self-hosting workflows into simple prompts, allowing users to run 200+ open-source applications directly from their own hardware while Cloudflare tunnels handle routing and security.

Who It's For & Problem Solved

Built for developers, indie hackers, freelancers, and anyone tired of monthly SaaS subscriptions for services their own machine could run. mycrab eliminates the traditional barriers to self-hosting: weekend-long configuration sessions, security vulnerabilities from exposed ports, and the technical complexity that kept self-hosting out of reach for non-technical users. It specifically targets the gap between powerful local hardware and the inability to make it internet-accessible safely and easily.

Key Features & Capabilities

• Agent-First Architecture: Single markdown skill file (MIT licensed) teaches any AI agent (Claude, GPT-4o, Gemini, etc.) to read APIs, install apps, configure tunnels, and deliver live URLs • 200+ Tested Applications: One-click install prompts for Gitea, Nextcloud, Ghost, Immich, and other open-source alternatives to paid SaaS (Dropbox, AnyDesk, ngrok replacements) • Zero Inbound Ports: Cloudflare tunnel sits in front—no router configuration, no exposed home IP, minimal attack surface • Permanent Subdomains: Free temporary addresses (agent-xxx.mycrab.space) or permanent custom subdomains (yourname.mycrab.space) with automatic SSL • Full API Access: Build custom tools on top, includes x402 payment layer for agents that earn while serving • MCP Support: Exposes local tools and data to AI agents via Model Context Protocol • Automatic Persistence: Agents configure systemd services or startup tasks for post-reboot reconnection

Typical Workflows

Users give their AI agent a single prompt containing the mycrab skill URL and their setup token. The agent reads the skill file, installs the chosen application (asking 1-2 configuration questions), starts the service, wires the Cloudflare tunnel, and returns a live HTTPS URL—typically within 2 minutes. Apps run on the user's own hardware (laptop, desktop, Raspberry Pi) with zero cloud hosting costs. The same permanent "crab" address can be reused across different projects.

What Differentiates It

Unlike traditional tunneling services (ngrok) that only pass traffic, mycrab integrates deployment, DNS management, and agent orchestration into one platform. The agent skill is the product—no SDKs, no libraries, just a markdown file that any capable AI agent can parse. This positions mycrab as infrastructure specifically designed for the AI agent era, where bots handle DevOps and humans own the outcome.
