About Catenary
Catenary is an integrated development environment for coding agents. It lets users run Claude Code, Codex, and Antigravity side by side, then switch between a multi-split TerminalMap and an infinite spatial canvas. Both layouts support organizing parallel agent sessions in a shared workspace. The application provides shared local Language Server Protocol support and Git worktree integration. LSP can provide code-aware information to tools, while worktrees allow multiple branches of a project to be checked out separately. The product description states that it has zero telemetry, emphasizing a local workflow. Catenary is intended for developers who coordinate multiple coding agents and want a visual way to manage their sessions and project contexts. The evidence does not explain how agent permissions are handled or whether all listed agents expose the same functions. Its core capabilities are side-by-side agent sessions, flexible terminal layouts, local LSP, and Git worktrees.
