Run many coding agents in parallel, each in its own worktree
Each agent gets its own isolated Git worktree, so multiple agents can edit, test and build concurrently without conflicts.
Works with Claude Code, Codex, Gemini, Cursor CLI, OpenCode, Copilot, Cline and many other command-line agents using subscriptions you already have.
A built-in browser lets you click any element to copy its HTML, styles and selector, or screenshot a page and drop that context straight into an agent prompt.
Review AI output, run commands and arrange terminals, browsers, files and diffs in panes shaped to the task at hand.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.

SpecialistAn AI-native code editor optimized for multi-file generation rather than managing multiple parallel terminal agent worktrees.
Provides an extensive platform and desktop command center for parallel AI coding agents, but with a heavier proprietary footprint.
#3SpecialistCognition's autonomous software engineer that ships real pull requests
SpecialistAn AI IDE that handles full-project coding tasks, but lacks Orca's multi-agent parallel git worktree orchestration.
Free / Open-sourceCombines mind mapping and project workflows with AI agents, but less focused on pure visual diagramming and wireframes.
Robust collaborative whiteboard with strong AI diagramming tools, but less polished UI wireframing capabilities than Whimsical.

Dedicated diagramming platform with strong AI chart generation, but less focus on freeform collaborative brainstorming whiteboards.
SpecialistInstantly turns natural language prompts into mind maps and flowcharts, but offers less freeform canvas drawing flexibility.
Combines whiteboarding and documentation with AI generation, but lacks Whimsical's specialized wireframe shape library.
Exceptional UI wireframing and prototyping tools, but less versatile for general mind mapping and freeform brainstorming.

A desktop workspace for coordinating multiple AI agent CLI tools, though less focused specifically on git worktrees.
