Free

A desktop workspace for running Codex, Claude Code, Grok, OpenCode, Kimi Code and Antigravity in parallel Git worktrees.

Parallel Tasks in Git Worktrees: Every task runs in its own worktree so multiple agents work simultaneously without colliding, with dependencies set when one change needs another.
Six Supported Agents: Assign Codex, Claude Code, Grok, OpenCode, Kimi Code or Antigravity per task, using each agent's own installed CLI and permission rules.
Interactive Codebase Map: Browse resolved file dependencies to trace the reach of a change and choose what to inspect next during review.
Carried-Forward Project Context: Save project guidance once; new tasks match relevant guidelines to the prompt, inherit defaults, and let you inspect what the agent actually received.
Unified Code Review: Read each result beside its original brief, combine related patches into one review, request another pass, and decide what enters the project.
Named Account Profiles: Keep work and personal agent accounts separate with per-project defaults and per-account usage tracking.
Agent Browser and Computer Use: A separate browser session per task lets agents navigate pages, fill forms, capture screenshots and run accessibility checks; Windows desktop control adds approved window clicks, typing and scrolling.
Cross-Agent Messaging: Tasks share a project inventory with ownership, scopes and dependencies, and agents can send direct task messages or project broadcasts through a durable inbox.

Running Experiments Side by Side: Try two different approaches to the same problem with different agents and compare the resulting patches before choosing one.
Reviewing Agent Output Safely: Keep every generated change behind a human review step, with checks attached to the code they tested.
Comparing Coding Agents: Assign the same brief to Codex, Claude Code and Grok to see which handles your codebase best.
Separating Work and Personal Accounts: Use the right provider account per project without re-authenticating or risking cross-billing.
Understanding a Change's Blast Radius: Use the codebase map to see which files a proposed change touches before merging it.
Automating Verification: Let agents drive a sandboxed browser to fill forms, screenshot results and run accessibility audits as part of a task.

Browser-native CFD: upload a 3D model and run a validated virtual wind tunnel — streamlines, pressure fields, lift and drag — all in your browser.

In-browser 3D Viewer: WebGL viewer that renders STL, OBJ, STEP, IGES, GLB, and FBX with orbit, wireframe, transparency, bounding box, and measurement tools.
Virtual Wind Tunnel: Animated streamlines, velocity vectors, pressure and velocity contours, vorticity, wake, and flow separation rendered live during the solve.
Full Flow Setup: Configure speed, direction, density, temperature, pressure, humidity, altitude, fluid, and turbulence model per run.
Engineering Results: Reports Cl, Cd, Cm, Reynolds, Mach, forces, centre of pressure, and surface maps — exportable to CSV and PDF.
Interactive Charts: Lift-vs-angle, drag-vs-speed, pressure and velocity histograms, plus residual convergence and mesh statistics.
Comparison Tool: Overlay two runs side by side and read a performance difference table across pressure and airflow.
AI Aero Assistant: Explains flow separation, high drag causes, and suggests design changes; can run on the user's own Claude key.
Validated OpenFOAM Backend: Parallel snappyHexMesh + simpleFoam in Docker, benchmarked to within about 10% of published wind-tunnel data.

Airfoil analysis: Study Cl, Cd, and stall behaviour on airfoils like NACA 0012 without booking a physical wind tunnel.
Drone frame optimisation: Simulate flow around quadcopter and drone frames to reduce drag and improve efficiency.
Automotive aerodynamics: Rapidly iterate on car body geometries and read off aero coefficients before CAD sign-off.
Rapid design iteration: Compare two design variants side-by-side and quantify aerodynamic improvements.
Teaching and demos: Run browser-based aerodynamics demonstrations without installing OpenFOAM locally.
BYO compute: Point Ventorah at a user's own OpenFOAM worker and Claude API key for private, unlimited runs.
