A single extension that works in both Antigravity IDE and Visual Studio Code. Connect your IDE to the FastBuilder.AI architecture engine and give every AI agent full context of your codebase.
What It Does
The UpperSpace IDE Plugin bridges your code editor to the FastBuilder.AI backend, giving you and your AI coding agents a live, continuously-updated map of your entire software architecture — the Golden Mesh.
Instead of AI agents guessing at your codebase structure, they get precise knowledge of every component, connection, data flow, and event in your project.
Who It's For
Developers using AI agents (Copilot, Cursor, Antigravity) who want those agents to truly understand their codebase — not just the file they're editing.
Tech Leads & Architects who want real-time visibility into how their codebase is structured and evolving.
Teams adopting AI-assisted development who need a shared, accurate architecture context across all IDE environments.

What You Get
Architecture-Aware AI
Your AI agents see the full picture — components, blocks, functions, data flows, and events — not just local context.
One-Click Dev Cycles
Start, stop, and manage development sessions directly from the sidebar. No context-switching.
Live Project Sync
The plugin stays connected to FastBuilder.AI via WebSocket, so your architecture context is always current.
Works Everywhere
Runs in VS Code, Cursor, and Antigravity IDE. Auto-detects your environment and adapts.
Sidebar Control Panel
Dedicated activity bar with project status, connection health, and stream controls — all at a glance.
Features
🔌 Connect — Link your project with one command. The plugin reads your upperspace.json config and connects to FastBuilder.AI.
▶️ Start Development — Kick off an AI-assisted development session. The backend dispatches architecture-aware prompts to your IDE's AI agent.
⏹️ Stop Development — Cleanly end the current session and preserve state.
🧹 Clear Memory — Reset the agent's conversation memory for a fresh start.
🔄 Reset Architecture State — Re-sync the architecture engine if you've made major structural changes.
📂 Open Artifacts — Jump directly to generated files and outputs from recent sessions.
📊 Status Bar — Always-visible indicator showing connection state, IDE type, and project readiness.
Getting Started
