What is devx?

devx is a developer experience CLI that provisions a fully-configured local development environment in a single command. It eliminates the three most common sources of developer friction:

Problem	devx Solution
"It works on my machine"	Deterministic Fedora CoreOS VM with pre-tuned kernel parameters
Accessing internal services	Zero-trust Tailscale mesh VPN, built into the VM
Webhooks & sharing	Instant public HTTPS via Cloudflare Tunnels (*.ipv1337.dev)

How It Works

devx vm init    # One command. Done.

Behind the scenes, devx provisions a Podman Machine running Fedora CoreOS, then injects an Ignition config that:

1. Installs Tailscale and joins your corporate Tailnet automatically
2. Creates a Cloudflare Tunnel with persistent credentials
3. Tunes the kernel — sets inotify limits, fs.aio-max-nr, and other parameters
4. Exposes ports through Cloudflare so external services (Stripe, GitHub webhooks, teammates) can reach your local machine

Who Is It For?

• Application developers who need a consistent, pre-configured container runtime
• Platform engineers who want to standardize the dev environment across a team
• Open-source maintainers who want to reduce onboarding friction to near-zero

Design Principles

• One CLI, everything — VM, tunnels, databases, agent skills, and site hosting are all subcommands of devx
• Convention over configuration — Sensible defaults (devx vm init works with zero flags), but everything is overridable
• Transparency — Destructive operations show an impact summary and require confirmation
• AI-native — Agent skill files and --json output make devx controllable by AI coding assistants
