Catenary
Spatial IDE that visually wires AI coding agents with smart cables
Visit website →About
Catenary is an all-in-one IDE that reimagines coding with AI agents through a spatial interface. Instead of drowning in dozens of overlapping terminal tabs, Catenary gives you an infinite 2D canvas where you can see and connect coding agents visually.
The standout feature is Visual Cables: physically wire agent terminals together to pipe context, delegate tasks, and build multi-model squads — like chaining a heavy reasoning model to a fast test runner. Each new task spins up an isolated visual workspace in one click without losing your previous flow.
It includes a native Monaco editor, WebGL-powered PTY terminals, and browser previews side by side. 100% local-first: zero telemetry, fully offline, your code and API keys never leave your device. Free for macOS, Windows, and Linux.

Why we picked it
Catenary earns its spot for Visual Cables specifically — physically wiring agent terminals together to pipe context between them is worth naming as a genuinely different mental model than a wall of overlapping tabs, for someone juggling several agents at once.
