What is OwlCAD?

OwlCAD gives makers, prototyping teams and schools a parametric CAD workspace that lives in the browser and is built around one goal: parts that are ready to print. Models are parameter-driven, so any dimension can be changed later and the geometry regenerates. Output is print-ready: Boolean results stay manifold, tolerance presets handle press, slip and loose fits, and a printability review catches overhangs, thin walls and non-watertight shapes ahead of export. Hollowing, lay-flat and material weight and cost estimates round it out. Modeling tools include sketching with constraints, edge-level fillets and chamfers, loft, sweep, patterns and datum planes, along with assemblies that support mates, an exploded view and a bill of materials. Over 30 generators produce gears, threaded parts, enclosures, bearings, hinges and Gridfinity bins. Files can be opened from STEP, OpenSCAD, STL, 3MF and OBJ, and saved to STEP, DXF, SVG, GLB, STL, 3MF and OBJ. Work is protected by local-first autosave plus cloud projects with version history and sharing. Designers can publish customizable models with adjustable parameters for others to tailor and download, and every plan, Free included, carries full commercial rights. The Free plan covers the entire editor, import, export and the customizer, with no time limit. Pro adds AI generation of editable parametric parts or sculpted meshes across several models, AI-assisted modifications, a monthly credit allowance, bring-your-own-key support, and MCP access for AI agents such as Claude Code, Claude Desktop and Cursor. For education, classroom mode is free for K-12, with pseudonymous student accounts and AI limited to teachers. The interface is available in English, Spanish, German and French, and a desktop edition is offered alongside the web app. No installation, and no account required to get started.

What is FreeCAD?

FreeCAD is a powerful, open-source parametric 3D modeling application designed for the creation of real-world objects in different sizes. The parametric modeling capability allows users to easily track the history of their designs and make adjustments to various parameters, thus streamlining the modification process. Users can create constrained 2D sketches that form the basis for building additional objects, enhancing the design workflow. The software includes a variety of tools for modifying dimensions and extracting detailed specifications from 3D models, which contributes to the generation of precise, production-ready drawings. As a cross-platform solution that works on Windows, Mac, and Linux, FreeCAD provides robust customization and extensibility features. It supports numerous open file formats such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, and DAE, facilitating seamless integration into diverse projects. Tailored for different applications, including product design, mechanical engineering, and architecture, FreeCAD appeals to a wide range of users. Whether you are a casual hobbyist, a seasoned CAD expert, a student, or a teacher, FreeCAD's intuitive interface ensures that everyone can utilize its capabilities effectively. The software thrives on community-driven development, continuously improving through user feedback and contributions, which helps it meet the evolving needs of its extensive user base. This commitment to ongoing enhancement makes FreeCAD not only a tool but also a collaborative platform for innovation in design.

Pricing Information

$12.00/month
OwlCAD is free to use. The Free plan has no time limit and includes the full parametric editor, import and export in every supported format, the customizer, cloud projects with version history and sharing, and the printability tools. You keep full commercial rights to anything you design, on every plan.

Pro is $12 per month, or $120 per year (two months free). It adds AI generation across several models, Modify-with-AI, AI-assisted customizing, and MCP access for AI agents. Pro includes 20 AI credits a month, which reset monthly. Light parametric generations cost one credit, and detailed mesh models cost a few. One-time credit top-up packs never expire. Pro users can also bring their own AI provider key and generate without spending credits. Payments are handled by Stripe, and you can cancel anytime with no contract.

Classroom features for K-12 schools are free. Districts can add a pooled AI credit budget for teachers; contact OwlCAD for details.
