Light Mode, Polished

Frontend

A proper paper-white light theme that reads beautifully in bright rooms, plus a small personal touch: rename yourself in the user menu without touching your GitHub or Google account.

  • Paper-white canvas with soft grid lines and theme-aware text across every panel
  • Config forms, validators, inspectors, and the component palette all respect your theme
  • Editable display name — click the pencil in the user menu to set a browser-local nickname
  • Your custom name is scoped per account and never leaves your browser
  • Colored buttons, status pills, and AWS service badges keep their contrast in both modes

MCP for AI Editors

  • Remote MCP server with OAuth 2.1, PKCE, and dynamic client registration
  • Five tools: list, get, import, export, and delete diagrams
  • Terraform ↔ CloudFormation round-trip preserves nodes and edges
  • One-click install for Cursor and VS Code; CLI for Claude Code and OpenCode
  • Per-user token scoping and audience-bound access tokens
