Free

Open-source library of agent skills for CAD, robotics, fabrication, and simulation — generate STEP/STL, URDF/SRDF/SDF, DXF, and slicer G-code from prompts.

Key features

  • Prompt-to-CAD Generation: The CAD skill creates and edits parametric CAD models from natural language or image requests, exporting to STEP, STL, 3MF, and GLB.
  • URDF Robot Description: Writes robot structure files with links, joints, limits, inertials, and meshes ready for ROS-based stacks.
  • SRDF for MoveIt2: Adds planning groups, end effectors, named poses, and collision rules on top of a URDF for MoveIt2 planning.
  • SDF Simulation Worlds: Creates simulator models and worlds with frames, physics, sensors, and lights.
  • 2D DXF Drawings: Produces cut-ready DXF profiles, templates, gaskets, and layouts from Python or CAD geometry.
  • G-code Slicing: Slices supported mesh files into validated, printer-profiled FDM G-code using real slicer CLIs.
  • Bambu Lab Print Jobs: Dry runs, uploads, and cautiously starts local Bambu Lab prints from validated G-code.
  • CAD Viewer Previews: Local browser previews for CAD, G-code, URDF, and other robot files for fast agent iteration.

Best for

  • Agentic Mechanical Design: Let a coding agent iterate on brackets, flanges, and enclosures directly from natural-language specs.
  • Robot Description Authoring: Generate URDF/SRDF/SDF files for new robot arms or mobile bases without hand-writing XML.
  • Rapid Prototyping: Take a CAD model to sliced, printer-ready G-code and kick off a Bambu Lab print from within an agent workflow.
  • Custom Part Fabrication: Produce DXF/STEP files pre-checked for SendCutSend, then order laser-cut or CNC parts.
  • Simulation Setup: Author SDF worlds for physics simulators with the right frames, sensors, and lighting for robotics research.
  • Off-the-Shelf Sourcing: Use step.parts to pull ready-made STEP models for common hardware like screws, bearings, and connectors.

Superapp

Paid

Create native iOS apps from ideas using AI, without writing code.

Key features

  • AI App Generation: Transforms natural-language descriptions and specifications into functioning native iOS app projects to accelerate ideation and prototyping without manual coding.
  • Native iOS Output: Produces native iOS artifacts (projects/packages suitable for Xcode or Swift/SwiftUI) enabling users to obtain platform-native binaries and App Store‑ready builds.
  • No-Code Editor: Provides a visual or guided interface for customizing UI layouts, navigation, screens, and basic app logic so non-technical users can refine generated apps.
  • Templates and Components: Offers pre-built templates and common UI components to quickly scaffold common app types and reduce time to a working prototype.
  • Preview and Testing: Enables live previews and device testing workflows so users can iterate on UI and behavior before finalizing the app.
  • Export & Publishing Support: Includes export options and guidance to prepare the generated app for distribution and submission to the Apple App Store.
  • AI-generated native iOS app creation without manual coding
  • Support for embedding web-based mini-apps into native superapps via Ionic Portals/Portals SDK
  • Mini-app build workflow using Node/npm (npm install; npm run build)
  • Requires Ionic Portals Key for iOS runtime embedding
  • Integration examples with Supabase backend and local development via Docker (npx supabase start)
  • Native project scaffolds for iOS (Swift) and Android (Kotlin) that auto-pull built mini-apps
  • Modular app architecture enabling multiple standalone apps (mini-apps) within one superapp

Best for

  • Rapid MVPs for Entrepreneurs: Quickly produce a native iOS minimum‑viable product from a concept to validate market demand without hiring an iOS developer.
  • Designer-to-App Handoff: Convert visual designs or product specs into working native iOS apps so designers can see interactive versions of concepts.
  • Small Business Tools: Build simple internal iOS apps (directories, expense trackers, order forms) without an in-house engineering team.
  • Educational Projects: Enable students and educators to create real native iOS apps for learning and coursework without deep programming knowledge.
  • Product Iteration: Allow product teams to iterate on app flows and user experiences rapidly by regenerating and customizing app builds.
  • Agency Rapid Delivery: Agencies can prototype and deliver client iOS apps faster by using AI generation and no-code customization as a baseline.
  • Rapidly prototype and deliver native iOS apps from ideas without hiring developers
  • Compose multi-service superapps by bundling multiple web mini-apps into a single native container
  • Run local/full-stack demos using Supabase and Docker for backend/data services
  • Provide a marketplace or hub of mini-apps (employee directory, expenses, CRM, HR, perks, time tracking) inside a single native app
