Review
CADViewer suits organizations that need to embed CAD drawing workflows in a browser-based application, especially when developers want control over deployment and integration. Its broad format support and markup tools are compelling, but full-server licensing is a substantial purchase and the trial lasts only 10 days.
Overview
CADViewer is a JavaScript and SVG library for displaying and manipulating CAD drawings in a browser. It goes beyond viewing with redlining, drawing comparison and API-based measurement, making it a better fit for teams building CAD into operational software than for an individual homeowner seeking a standalone drawing viewer.
Tailor Made Software has operated since 1990, with offices in Seattle and Stockholm. CADViewer is offered for cloud or on-premises installation, so organizations can choose where it runs; that flexibility comes with integration and licensing decisions a simple desktop viewer avoids.
Key features
Formats, markup and measurement
Supported formats include DWG, DXF, DWF, DGN, SVG and SVGZ, as well as PDF, PNG, JPG, GIF and TIFF. That range can bring CAD drawings and common image or document formats into a shared browser workflow. Users can mark up drawings, compare two drawings and measure through the API, useful for review and coordination without limiting the product to passive display.
Integration and deployment
JSON interfaces and a rich API support integrations with React, Angular, Vue, PHP, NodeJS, .NET, .NET Core and Servlets. Listed integrations include Nextcloud, Leaflet, OpenStreetMap, SharePoint, IBM Maximo and IBM Tririga. This breadth gives developers room to connect CAD data to existing systems, but it also means CADViewer’s value depends on having an application or workflow to integrate it with.
The maker describes browser integration across platforms, including Android and iOS, and lists web, mobile, desktop, Linux and self-hosted availability. The product’s uses include space management, CAFM, inventory and document management, IoT, maintenance, real estate operations, and CAD visualization and collaboration.
Pricing
The 10-day full-server trial costs 0.00 USD and requires trial license keys obtained through the store after registering for the download and providing installation details. The download page also asks for an email address to receive links to CADViewer and its converters. That short evaluation window favors teams prepared to install and assess the software promptly.
The full-server subscription costs 2444.00 USD per year, billed $2,444 a year. It is the recurring option for organizations that want a full server license without the one-time outlay. The full-server license costs 4190.00 USD per once, a larger upfront cost that may suit a fixed deployment expected to remain in use. Perpetual licensing is a special exception for users with a fixed MAC/IP environment or alternative fixed domain, under contract; it is not a general substitute for the subscription.
There is no free plan. For contractors or homeowners who only need to inspect drawings occasionally, these full-server prices and the implementation-oriented product may be more than the job requires.
Platforms
CADViewer is listed for Android, iOS, Linux, macOS, Windows, web, API and self-hosted deployment. Browser integration across platforms can make drawings accessible without confining the workflow to one desktop operating system, while on-premises installation offers an alternative to cloud deployment.
Who it's for
CADViewer is strongest for software teams and organizations embedding drawing access, markup, comparison or measurement into facilities, maintenance, inventory or real-estate operations. Its API and framework coverage are meaningful advantages when those systems already exist or are being built. It is a weaker match for a small construction firm looking for an inexpensive, ready-to-use viewer rather than a full-server product to integrate.
Pros and cons
- Pros: Broad CAD and document format support, including DWG and DXF, lets teams handle varied drawing files in one browser-oriented tool.
- Pros: Markup, comparison and API measurement support review and coordination workflows rather than viewing alone.
- Pros: Cloud or on-premises deployment, plus extensive developer interfaces and integrations, suits organizations connecting drawings to business systems.
- Cons: Full-server licensing costs 2444.00 USD per year or 4190.00 USD per once, which is a significant commitment for occasional viewing.
- Cons: The trial is limited to 10 days and requires registration, installation details and trial keys, leaving little room for a casual evaluation.
- Cons: Perpetual licensing is restricted to specific fixed-network or fixed-domain arrangements under contract.
Alternatives
Browse CAD viewers for a broader comparison of drawing tools. Choose CAD Reader if a free plan and Android, iOS, macOS or Windows support matter more than CADViewer’s server-oriented integration approach. DWG FastView is a freemium option for teams seeking mobile, web or self-hosted access; its Premium plan is 3.99 USD per month and includes 5G cloud storage, premium annotations, dimensions and measurements, and removal of mobile ads. CAD Pockets offers a free plan with fundamental CAD features, third-party cloud storage and 100MB of cloud space, making it an option for users prioritizing a free entry point.
Glovius is another freemium choice, with daily and weekly usage packs for users who prefer time-limited purchases. ABViewer may suit users who want a paid Linux or Windows viewer with a trial and a three-month subscription option. DWGSee is a freemium alternative for Android, macOS, web or Windows. 3D-Tool is worth considering for Windows users who need its free viewer for DDD, STL and 3MF files and can accept that it cannot export CAD files. Guthrie CAD Viewer is a paid Windows alternative with a 21-day trial and a one-time Standard License.
Verdict
Choose CADViewer when your organization needs to build browser-based CAD review into a larger application and can make use of its deployment choices, APIs, markup and measurement tools. Its breadth is the reason to choose it; the full-server price and integration-focused model are the reasons to look elsewhere if you simply need an affordable viewer for project drawings.
