Catenary

Freemium

Local-first spatial IDE that orchestrates Claude Code, Codex, Cursor, and other coding agents on an infinite canvas with visual context wires.

Infinite Canvas: Terminals, Monaco editors, browsers, and git worktrees float on one pannable, zoomable surface so every agent stays visible at once.
Context Wires: Drag a directed wire between panels to pass context to another agent, set to relay automatically or act as a standing permission.
One-Click Worktrees: The New Task button creates an isolated branch, working directory, and agent, colour-coded across sidebar, dock, and canvas.
Monaco Diffs: VS Code's editor inside the canvas with git-aware file tree and side-by-side diffs of everything an agent touched.
Maestro Mode: One agent recruits, briefs, and wires a team of up to ten helpers, with an editable approval card before every action.
Multi-Project Parallelism: Run several projects at once, each with its own canvas and multiple isolated branches, with state preserved on switch.
Local-First Privacy: No account, no telemetry, and zero bytes of source code, prompts, or keys sent anywhere; only two outbound hosts total.
Bring Your Own Keys: Agent CLIs talk directly to Anthropic, OpenAI, or Google with your own keys, or to Ollama and LM Studio on localhost.

A developer runs three coding agents on separate branches simultaneously and watches all of them without losing track of any.
An engineer delegates a specific subtask from one agent to another by dragging a wire instead of copy-pasting context between windows.
A team working under strict data policies needs an agent IDE that provably never uploads source code.
A solo builder ships several experiments in parallel isolated worktrees without polluting the main working tree.
A reviewer wants side-by-side diffs of agent-authored changes before deciding what to keep.
A user orchestrates a self-organizing squad of agents while keeping human approval on every structural change.
