Harth vs. Autodesk Viewer — free universal browser viewing vs. AI-assisted collaborative architectural model review; formats, collaboration, and fit.
Harth vs. Autodesk Viewer: Browser Model Review (2026)
Direct answer
Autodesk Viewer is a free, no-install browser viewer that renders a wide range of CAD and BIM files for quick look-and-measure review. Harth positions itself as an AI-assisted browser workspace for architectural model review and client collaboration — aimed at review, comments, and AI-assisted checks rather than just viewing. If you need a free universal viewer, Autodesk Viewer is the baseline; if you want collaborative, AI-assisted review in the browser, evaluate Harth against your workflow. Verify Harth's current feature set against the product.

Frequently asked questions
Is Autodesk Viewer free?
Autodesk Viewer is offered as a free online viewer for a broad set of 2D and 3D formats, aimed at quick viewing, measuring, and markup in the browser. Confirm current terms and supported formats on Autodesk's site, as offerings change.
What does Harth add over a plain viewer?
Harth positions itself as more than a viewer — an AI-assisted browser workspace for reviewing architectural models, collaborating with clients, and running AI-assisted checks. Because product capabilities evolve, verify Harth's current review, collaboration, and AI features against the product before comparing feature-by-feature.
Which should I use for a quick client look?
If you just need someone to open and inspect a model with no setup, a free viewer like Autodesk Viewer is the low-friction baseline. If you want threaded review, collaboration, and AI-assisted checks in that same browser context, evaluate Harth.
