GretlNever wonder what's running on port 3001 again

Gretl — Control Panel for Your Localhost

Gretl is the missing control layer for local development. Replace cryptic port numbers with memorable names, manage services across CLI, desktop app, and browser, and boot entire stacks with one command.

Product Highlights

• Name-based addressing: Register services once and address them by readable names like jobs-server instead of :7401
• Universal interface: Control everything from CLI, native desktop app, browser extension, or SDKs — one daemon, four surfaces
• AI-powered control: Built-in MCP server lets Claude Code query ports, start services, and manage groups conversationally
• Smart grouping: Define service stacks in gr.toml with dependency ordering and health checks
• Auto-detection: Instantly adopt any running service — Vite, Postgres, Python scripts — without manual configuration

Use Cases

• Microservice development: Run multiple interconnected services locally with automatic dependency management
• Full-stack teams: Share gr.toml configs so every developer boots identical environments from the same repo
• AI-assisted workflows: Ask Claude which services are down and start them without leaving your editor
• Browser-centric development: One-click access to any localhost service directly from Chrome toolbar

Target Audience

Gretl is built for developers running complex local environments — backend engineers, full-stack teams, and platform engineers who need reliable, shareable service management across CLI, GUI, and AI tools.
