Used Catenary for Mac?
Editors’ Review
Catenary, developed by Giorgio Nícolas and a team, is an infinite spatial canvas IDE and terminal orchestrator for AI-native developer workflows. It replaces stacked terminal tabs and narrow chat sidebars with a 2D workspace that hosts multiple AI agents and code artifacts in parallel, and combines a Monaco-based editor, native PTY terminals, and browser previews. The app targets software engineers who coordinate multi-agent coding tasks and need a private, local-first environment to manage complex workflows visually.
It reconceives multitasking by mapping terminals and editors onto a 2D plane
The app provides an infinite spatial canvas that replaces traditional tab sprawl with a persistent visual map, letting developers place code files, terminals, and agent windows where they make sense. Key surface integrations include a Monaco-based code editor, native PTY terminals, and in-canvas browser previews, and users can create isolated Task Islands to keep separate efforts visually distinct. This layout aims to convert scattered tabs into a single, spatially organized workspace.
It makes multi-model context passing explicit through visual wiring
Visual Cables let terminals and agent windows connect so context flows between AI agents without manual copy-paste, enabling the construction of multi-model "squads." The tool orchestrates parallel agents such as Claude Code and can route outputs between them, which helps when a task needs sequential or complementary model steps. This wiring model targets workflows that depend on passing prompts, intermediate results, or state between separate agents.
It expects integrations with cloud and local models and a canvas-oriented workflow
The app connects to providers including Anthropic, OpenAI, and Google, and it supports local models via Ollama or LM Studio, so input sources range from cloud endpoints to on-machine runtimes. That flexibility requires users to configure provider credentials or local runtimes. Developers who prefer linear, tab-based interfaces may need time to adapt because the core interaction model uses spatial placement rather than stacked tabs.
Its local-first design favors code privacy while offering multi-platform builds
The developer built the tool with a local-first philosophy and zero telemetry so source code, prompts, and terminal outputs remain on the machine, and the app can operate with local models offline. Native macOS experience is emphasized, with Universal builds for Apple Silicon and Intel, while additional packaged builds exist for Windows and Linux. Those deployment choices shape where and how teams can adopt the app in different environments.
Pros
- Persistent 2D workspace replaces terminal tab sprawl with a visual map
- Visual Cables enable direct context piping between agent terminals
- Local-first architecture enforces zero telemetry and supports local models
- Integrates Monaco editor, native PTY terminals, and browser previews
Cons
- Canvas layout requires adaptation from developers used to tabbed UIs
- Configuring cloud providers or local runtimes requires extra setup
- Visual wiring can add complexity for single-agent, simple tasks
Bottom Line
Practical, purpose-built choice for developers coordinating multiple agents
Catenary is a practical option for developers who coordinate multi-agent coding workflows and prioritize on-machine privacy; its visual, canvas-first approach favors spatial organization over linear tabbing. The learning curve rewards users who map processes visually but may slow adoption for engineers who rely on traditional tab stacks. In short, it suits teams that need to centralize agent interactions and protect local source material.
