Build Terraform infrastructure visually. Browse a module registry, wire inputs and outputs on a canvas, and generate production-ready .tf files — all inside VS Code.
Features
Visual canvas — Drag-and-drop module composition with a node-based editor
Module registry sidebar — Browse, search, and inspect modules without leaving VS Code
Wire inputs and outputs — Connect module outputs to other module inputs visually
Configure everything — Variables, outputs, providers, locals, and environments through dedicated config panels
Generate Terraform — Produce production-ready .tf files with one click
Terraform tooling — Validate, format, security scan, and generate docs via integrated terminal commands
Auto-save — Optionally auto-save canvas changes as you work
Run Lace: Open Canvas from the command palette (Cmd+Shift+P / Ctrl+Shift+P)
Browse the Registry sidebar (Lace icon in the activity bar) to find modules
Click a module to view its details, then Add to Canvas
Wire module outputs to other module inputs by dragging connections on the canvas
Configure variables, providers, and other settings through the config panels

How It Works
Lace connects to a module registry through its CLI backend. When you add modules to the canvas and wire them together, Lace maintains a project file (lace.json) that captures your composition. When you generate, Lace produces standard Terraform files (.tf) from your visual design.
All project files live in a .lace/ directory at your workspace root. This directory is meant to be version-controlled alongside the rest of your code.
