Overview

Onshape is a browser-based 3D CAD platform for designing parts and assemblies, with parametric modeling and product data management built into the same service. It is best suited to product-design teams that need shared editing and controlled design changes; the central trade-off is that commercial work starts at $1,500 per user per year.

Its combination of browser and mobile access, collaboration, and built-in data controls makes it a compelling fit for teams that want design work and revision management together. The free plan is useful for non-commercial projects, but public documents make it unsuitable for confidential work.

Onshape also sits within 3D CAD Software, CAD software, and 3D modeling software.

Key features

Parametric design and production workflows

Parametric modeling covers solids, surfaces, and sheet metal, with dedicated sheet-metal tools and assembly design. That range supports work on both individual components and assembled products. A built-in render engine and STL and OBJ mesh support add visualization and file-exchange options, while 3D-print export supports a path from design to fabrication.

Simulation supports linear static and modal analysis for examining stress, deformation, and natural frequencies. CAM covers machining from 2.5-axis through 5-axis machines. Together, these capabilities extend Onshape beyond modeling, though teams should weigh the plan cost against the specific production workflows they need.

Collaboration and product data management

Multi-user editing, instant sharing, real-time communication, and access controls are designed for teams working on the same product. Built-in PDM adds edit history, version control, release management, search, and design-data sharing. Branching and merging and infinite undo give teams additional ways to manage changes; this makes Onshape especially attractive when coordination and traceability matter as much as geometry.

Updates arrive every three weeks without installations or downtime, reducing the maintenance burden of keeping design software current. Integrations include Slack, Arena PLM, Altium Designer, FeatureScript, a REST API, and the App Store, giving teams several routes to connect Onshape to adjacent tools.

Administration and security

Enterprise adds advanced administration, single sign-on, role-based access, guest users, and IP audit trails. Onshape Government runs on AWS GovCloud and helps meet ITAR and EAR requirements. Professional and Enterprise customers retain company ownership of design data when users are removed, a useful safeguard for organizations managing team changes.

Pricing

Free Plan

The $0.00 USD per free plan permits non-commercial use and provides unlimited public storage. All documents are publicly accessible, so it suits learning, personal projects, or work that can be shared openly—not commercial design or confidential development.

Standard Plan

Standard costs $1,500.00 USD per year, billed annually. It provides professional CAD for commercial use, built-in data management, and unlimited private storage. This is the lower-cost paid option for commercial users who need private documents, though Professional is the step up for company-managed data, release management, advanced PDM, and simulation.

Professional Plan

Professional costs $2,500.00 USD per year, billed annually. It adds company-managed data, release management, advanced PDM, and simulation, making it the stronger fit for teams with formal release workflows or analysis needs. Qualified professionals can try Professional free for up to six months through the Discovery Program, with no credit card required.

Enterprise

Enterprise uses custom pricing for large companies needing enterprise CAD and PDM. It includes custom release management, analytics and dashboards, an Arena PLM connection, advanced administration and security, and priority support. Its price is a matter for a company-specific quote rather than a published per-seat rate.

Platforms

Onshape runs in a browser and offers apps for iOS and Android. That reach is useful for teams who need access across devices, while browser-based delivery and updates every three weeks avoid software installations and planned update downtime.

Who it's for

Onshape is a strong choice for product-design teams that collaborate on parts and assemblies, need version and release controls, and want CAD, PDM, and selected simulation and CAM capabilities in one environment. Standard suits commercial users who need private storage; Professional is more appropriate when advanced PDM, managed data, release workflows, or simulation justify the higher annual price. The free tier makes sense for non-commercial work only when public documents are acceptable.

Look elsewhere if commercial work must start below $1,500 per user per year, if designs cannot be public but a paid plan is not feasible, or if the required platform or workflow does not match browser and mobile access.

Pros and cons

Pros: Parametric modeling spans solids, surfaces, and sheet metal, with assembly design, rendering, and 3D-print export in the same platform.
Pros: Multi-user editing and built-in PDM bring collaboration, version control, and release management into the design workflow.
Pros: Browser access, mobile apps, and updates without installations or downtime reduce deployment friction.
Cons: The free plan is non-commercial and makes every document public, ruling it out for private commercial projects.
Cons: Commercial use starts at $1,500.00 USD per year, and Professional costs $2,500.00 USD per year.
Cons: Enterprise pricing is custom, so large organizations must seek a quote to assess the cost.

Alternatives

SOLIDWORKS is worth comparing for teams considering a freemium CAD option with a listed Design Standard with Cloud Services plan at $2,820.00 USD per year, billed yearly.
Rhino 3D is an alternative for buyers weighing a paid tool with a permanent-license option; its listed commercial Rhino 8 license is for one concurrent user.
Shapr3D is another freemium option, with a free Basic plan limited to two projects and a Pro plan at $299.00 USD per year, billed annually excluding VAT.
CATIA is another paid CAD platform to consider.
Creo is a paid alternative with web, desktop, and mobile platform support.
Autodesk Inventor is a paid, Windows-based alternative with a free trial.
Siemens NX is another paid option for web and Windows.
AVEVA E3D Design is a paid alternative with web, Windows, API, and self-hosted access.

Verdict

Choose Onshape if your team wants parametric CAD, collaboration, and design-data management in a browser-based service, with simulation and CAM available for broader workflows. Its strongest reason to buy is the integrated approach to shared design and controlled revisions; its clearest reason to look elsewhere is the annual commercial entry price, especially if the free plan’s public, non-commercial terms do not fit your work.
