# Which browser-based CAD viewer has the best performance and markup tools for teams doing design reviews without emailing files back and forth?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">The email-the-file-around loop is exactly what design review tools are supposed to kill, so I looked at which browser-based options reviewers actually trust for performance and markup.</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/autodesk-viewer/reviews"><strong>Autodesk Viewer</strong></a>: Reviewers describe it as an easy web platform for sharing 3D models and coordinating markup, no install required. The honest limit that came up more than once: people wish the markup toolset had more options and depth.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/onshape/reviews"><strong>Onshape</strong></a>: Browser-based and built for real-time collaboration inside a single document, with revision history reviewers love for reverting or branching. It's full CAD rather than a pure markup tool, so it shines most when the reviewers are also the design team.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/design-review/reviews"><strong>Design Review</strong></a>: Worth a mention even though it's a desktop app, not browser, because reviewers specifically praise its change-tracking across a project lifecycle and smooth performance on low-end hardware. A good fallback if browser markup feels thin.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">For teams running weekly reviews, has browser markup been enough, or did you need a dedicated tool with proper approval tracking? And has anyone found Autodesk Viewer's markup limitations to be a real blocker, or just a minor annoyance?</p>

&lt;p&gt;&lt;span style=&quot;background-color: transparent; color: rgb(0, 0, 0);&quot;&gt;Yeah, removing the email-the-file loop is the whole point, so the real test is whether browser markup is deep enough to keep people from falling back to it. Thin markup tools are a common gripe, and they matter most when reviews need proper approval tracking rather than just comments. Worth separating &quot;enough to annotate&quot; from &quot;enough to run a formal sign-off,&quot; since those need different tools.&lt;/span&gt;&lt;/p&gt;
